ron petrucelli (December 17th, 2006) STRENGTHS: Serious power but refinement as well. WEAKNESSES: Long break in time - 72 hours recommended but more like a week for best results. REVIEW: I purchased this sub because I wanted something that was easily removable, and possessed good sound quality. I had no interest in waking up the neighbors late at night. I got everything I wanted and much, much more. It has awesome looks in my opinion and sound quality to back it up. Bass is very tight, with little overhang and sounds equally well on music ranging from acoustic to hip hop. And boy it hits hard, even when pushed. I ran the recommended 500 watts into it from a hifonics amp with outstanding results. However, I probably would have been equally happy with half that, provided that it was quality power. Those idots that have complained of blowing the VC obviously did not take the time to break in the unit or fed it cheap power. If you give this sub what it needs, you'll have no regrets.    coolhuy_gan (October 3rd, 2006) STRENGTHS: really good pounding base WEAKNESSES: not att all REVIEW: mann this subs base is so tight i like this sub sounds like two 12's my whole trunk shakes hitts really hard i like it    Tarik (June 28th, 2006) STRENGTHS: very tight bass, hard hitting, great sub if you're looking for single driver systems WEAKNESSES: not so sure about the 500W RMS... i ran a Polk Momo C300.2 with the level barely a 1/2 turn and burnt the coil REVIEW: great subs, nice looking..I had 1 in my trunk and had got plenty of rumble. 2 weeks in and without any real abuse (did turn it up a few times) it lost substantial SPL and got that funny smell.I took it to the audio shop and they said it's reading low Ohms and that it's gone. So i bought another one and 2 weeks later bang..same thing happened again.Now both of them are dead in my basement. I love the sound but can't afford to buy one every 2 weeks.Unfortunately i do not have their receipts for the warranty.    Andy (May 26th, 2006) STRENGTHS: Clean, solid bass, stlyeish, sounds awesome WEAKNESSES: I never kept em in their original box, but long break in period, 28hrs REVIEW: Probly the best thing I have ever bought. Hits hard, sounds clean, couldnt ask for better subs, I have 2 mm12s in a 3port box,somtimes it bangs so hard, you cant breathe =) if your looking for somthin that sounds great, definatly pick one of these bad boys up    Colbey Moak (February 25th, 2005) STRENGTHS: Glass inclosure and mm12 really compliment each other well. WEAKNESSES: None. Not for people that don't want massive bass. REVIEW: Very Stylish, Glass Amazes All, Hit Like 15's. I have a 99 s-10 extended cab and i have three of these babys in the back. These speakers are the hardest hitters i've ever heard. Mine are powered by nearly nothing at all at 300w, awful i know, but the speakers in these boxes make up lots of slack. Example: the other day i was haven a little bass match with one 15 and 2 tens powered by a true 1000w and i spanked the crap out of it. They are pricey i know but worth the money.    Brad (October 14th, 2004) STRENGTHS: Style, loud, clear sound and hit hard. WEAKNESSES: They are front heavy and i didint want to bolt them in my car so i attatched velcro to the bottom and rubbed it into carpet in the trunk, they havent tpped over at all since REVIEW: I have nuthing but love for my polk audio momos. They hit louder then any sub i have put them against. They look sweet also. I have 2 sitting in my trunk run by a sony 1000watt xplod amp.    Marco Obillo (August 30th, 2004) STRENGTHS: little space .. big sound. WEAKNESSES: long break in period.. REVIEW: Hey guys.. i've been building systems since i was a soph. in high school .. and now i'm a soph. in college.. i still do the same thing.. and through out the years.. i've learned to trust the name POLK for subwoofers or speakers.. I have a 2005 Altima with 2 pairs of 6.5's...a pair of 6x9...and a pair of the mm6 on my dash.. PLUS my 2.MM12.. in a custom fabricated enclosure.. pushed by a memphis 1000D amp.. this set up is frickin' awesome..not too low... not too bright like infinity..another car that i decked out w/polk is my g'f's...2004 Camry ... 2 sets of 6x9 db ... and a 12 dvc in the trunk .. still trying to save up for the components... all these are pushed by a 5 channel MTX AMP... they're not as loud as mine... but for her they're plenty loud.. i took my car to a drag and i got a pretty high decible reading count... alot more than those other clowns expected at the drags...i gotta admit.. it wasn't cheap but it sure took out them audiobahns.. infinity...L5's and type R.    V-DUBZ (August 9th, 2004) STRENGTHS: Style WEAKNESSES: single voice coil @ 4ohms (come on, would it have hurt to make a DVC version) Smacks the grill a lot! Can't handle rappid highs. Longest break'n period I have ever herd of. Box will eventually leak. Very weak voice coils (will burn at the drop of a hat) fi you buy this all your paying for is MOMO's style. might as well buy a Audiovox sub and put a MOMO sicker on it because that's what you get with the MM12 REVIEW: I bought this sub the same reason every one else did, I wanted some good sound quality and style out of my sub, all I ended up getting was a nice looking piece of junk. I got a mmomo C300.2 amp pushing it @ 445RMS @ 12.5volts. SAVE YOUR MONEY!    Mike (May 3rd, 2004) STRENGTHS: The good part about this sub is that I got it fairly cheap on the 1 day sale as stated above for 160$ with tax. It hits hard enough for me and has nice sound. It also saves space if you have a small vehicle. I drive a 03 camry and its a fairly nice size sedan and has alot of trunk space so this sub box sits nicely and still gives lots of space for cargo. WEAKNESSES: none that I have seen so far. REVIEW: First off I bought this sub at Frys on a 1 day sale for 147+ tax so it came out a bout 160$. Then it went back up to retail 400$. This is my first sub in my car. Knowing im not spending a couple of hundred of dollars for a sub and another few *high* hundreds on a amp I just wanted something more than just a new deck and new 6x9's. I went with this Sub because it came inclosed as a set package and therefore I didnt have to buy an additional enclosure. As I hooked up this sub with the polk/momo 500.1 sub and listened to music it sounds nice for 1 sub.    Ryan (May 1st, 2004) STRENGTHS: suprizingly loud for its size. lows are as good or better as ////|LPINE Type R's WEAKNESSES: ther is no weeknesses, if you have money, buy the dang thing, its well worth it REVIEW: Well, first of all, the rubber hitting the grill is just bogus. i am running a Profile CA1200 (1200 watts, about 500 RMS)to one of them and eazaly puts it to work. it maintaines its strenght at high volume levels, but wasnt coming close to the grill. unless you love to distort your subs or your pumping alot of watts into this sub, dont worry about the grill. Second, the lows, they hit fine. once agian if your pumping alot of watts to these subs, our your a sound freak, your just not gona hear the lows very well on any sub under $300 Heres a comparison, i have 2 12" type R's in a saturn sc2 runing off the Profile CA1200. suprizingly they MM12 hit atleast 2/3 of my Type R's and could still get louder! if you have the right amount of power and not a "760 Watt" Sony amp, then the sub will come back quick enough and sound good and your lows with be more responsive.    Joe (April 29th, 2004) STRENGTHS: The best looking speakers I have seen in years WEAKNESSES: The rest. REVIEW: Boy, was I duped. I thought I was getting the Best deal ever. I got $399.00 speakers for $99. I thought that was the best deal ever. Now, I know why. I can't believe all of the Nasty reviews for these 12 " Polk audio Momo MM12 subs. Many of the things said by the speakers enthusiasts are true. They sounds petty bad for being speakers valued at $399.00. My cousin (speaker expert) kept telling how bad the lows were. I kept telling him that it could not be the speakers because they were very expensive Polk Audio competition subs, but he kept insisting that it was the speakers. He was right. These speakers suck even at $99.00. I'm going to return them. I can't believe Fry's Electronics is still selling these recalled speakers even at that price.    devilchrist (April 1st, 2004) STRENGTHS: Pounds hard. nice and deep at low volume. Hit's harder then JLW612V2 WEAKNESSES: at higher volume does not hit deep but hard... Deffinitely underrated power rating... REVIEW: I had 2 of the MM10's running off sound stream amp @1200W @2 ohm setup.. and it sucked... I thought i would give it a try with 1 sub and the 800W at 4ohms that sound pretty damn nice.. so I decided to returnthe 2 subs and get a single MM12.. DAMN... I think I just found the sub. Running at +8db gain and at somewhere around 800-900W the sub sound great!.. as long as I don't push it too hard it will be find I suppose. AND i picked it up for 200$    ND40oz (February 21st, 2004) STRENGTHS: Can handle 500w, clean sound, small box WEAKNESSES: Only 4ohm, can't hit anything low REVIEW: I bought this sub for my daily driver back and forth into work each day. I wasn't expecting much just needed to add bass to the car, I have alpine type s's 6 1/2s all around. The nice small encloser fit in the back of the integra nicely and still gave me room to carry a few things. What I'm most disappointed in is the fact that they have no low frequency response. I have 2 JL10W0s in other car paired with a JL 500.1 amp and they go so much lower then this 12. I don't get how the 10 inch JLs can go lower then the "best" Polk 12". Oh well, needless to say, if I had to do it all over again, I probably wouldn't buy the polk. Just thought I'd try and throw some money back into the Maryland economy, but next time it will be going to Florida for some JLs.    stoner (February 11th, 2004) STRENGTHS: loud as hell pounds hard WEAKNESSES: none you ****heads REVIEW: damn nice subs if your not a cheap ***** and cant afford them.    Anthony Vargas (January 18th, 2004) STRENGTHS: great product, small footprint, amazing sound quaity, and it looks good! WEAKNESSES: rubber bounces off grill, long break in period REVIEW: ok first of all to you idiots who bew your sub within the first couple of months or even hours, do you have ne clue that a sub reqires a break in period, this means that you have to play it at resonable volume levels for about 72 hours, so that means you cant just plug it in and blast it, its common sense, im 17 years old and this is my second audio system that i purchased and it is great i broke my sub in properly and it sounds better, and plays louder than most of my friends two 12's, and i only own one of the polk mm12's. I am powering it by a rockford fosgate 501s (500w RMS and 1500 peak) and it seems to handle the power quite well. and the whold surround bouncing off the grill was an easy fix i took off the grill and the problem was solved, i thik that polk did an awsome job designing this sub even tho they did not relise the lack of intellegence some of the buyers had, i think that it is a great prodct it sounds great with my 4 mm6 coaxials, and looks great in the back of my 240sx next to my nitrous bottle.    Colin A. Eliot (December 14th, 2003) STRENGTHS: very attractive, good sound quality, small footprint WEAKNESSES: only available in 4 ohm model..doesnt even couple well with Polk's own mono block amp (unless you bought 2 of the MM12s). requires a lot of power to sound good. REVIEW: I purchased this sub because I got a great deal on it and I thought it was the best looking sub I had seen in a long time. The plexiglas enclosure is very classy. I coupled it with a Polk 500.1 and it sounded good, but not great. It is my own fault for pairing the 2, but I just was not satisfied. Since it is a single voicecoil 4ohm sub, I was only getting about 350w out of the amp. Since I consider an amp the cornerstone of a system, I hand to change out subs to get it at 2ohms and get all 500 (actually 550) watts out of it, so I went with an Alpine Type-R DVC 12". (space was a major concern for me, so I couldnt just buy another MM12, or else that is what I would have done). It is a very clean sounding sub, but in my opinion did not sound too terribly deep or loud    Kenny (December 6th, 2003) STRENGTHS: Cleanest bass you'll hear at levels that won't blow your eardrums. Looks damn cool too. WEAKNESSES: Long break in period? Rubber bounces off the grill. Requires lots of power. REVIEW: Maybe my problem is that I didn't break the subs in enough, but I've blown 2 in the past 6 months. Fortunately Polk is very nice about sending out a new unit when they receive your broken one, and they do it for 3 years. This time it's getting broken in right, so I'll see how it hits when I come home for Christmas. I use a Rockford Fosgate 800.2 amp, which is more than enough power, but it can't seem to handle all that much. Sub doesn't hit as hard as others (I used to use 2 Infinity's using the same amp, so half the power per sub and they were still louder) but the bass it does put out is amazing. The only thing that really bothers me was the rubber surround hitting the grill. It almost creates a reverse bottoming out and it sounds like hell every time it happens. I don't recommend cranking the volume with a lot of continuous bass, as this is how I blew mine up. First song that blew it up was Eminem's "Without Me", and the second was Lil John's "Bia Bia", just for examples. The box is small too, and all you need is one sub so you will still be able to use your trunk.    Aaron (November 13th, 2003) STRENGTHS: Bass the way it was recorded and meant to be heard. WEAKNESSES: Sometimes the sub bounces off the grill. REVIEW: Are there "louder" subs? Yes, but they don't sound as good. Are there "better sounding" subs? Yes, but they cost way more. Are there subs that play lower? Yes, but they're in a much bigger box. My point is that there isn't anything out there that sounds this good, looks this cool, plays this low and cost this little. This sub kicks ass!    Woody (October 29th, 2003) STRENGTHS: Clean hits, not overpowering, but responsive throughout the whole chord. WEAKNESSES: None. It is a great design and does not require any changing REVIEW: I believe sound has alot of influence on what people consider good or bad. I recently purchased this combination enclosure after trying many subs that was not only costly but ignorant. This sub does a great job of enhancing music. If you want something to out do the car next to you, then consider a another sub, however if you want reliable sound, clean bass hits, and just enough music for you and your passengers ears, this sub works very well. I do not think it is overated but just right. Modest, sleek and clean sounding. With the right amp, correct wiring, and accomapnied c player this sub is well worth th money. I prefer you spend less money and buy this sub, than second guess with other speakers an box combinations that just will not give you he same results. After all, they are the engineers, how much do we really know?    James Currier (October 18th, 2003) STRENGTHS: Nice clean low notes Decent spl out of a sealed box WEAKNESSES: long break-in period REVIEW: I have been a long time fan of polk car audio, and will continue to be. These subs hit pretty hard and also get plenty low. I just don't understand how some people say they do not hit low. I have heard plenty of systems to make the judgement, and say that they hit the nice low notes. They hit harder, lower, and much more crisp compared to the 15 inch MTX Thunder 8000 I had. To top it off I got an excellent deal on these subs from Circuit City. Thanks,POLK!!!!!!!!!!!!!    Jose Peralta (September 12th, 2003) STRENGTHS: sound reproduction, asthetics - they are beautiful subs WEAKNESSES: none REVIEW: I'm running 2 of these off of a MTX 801D and the sound reproduction is perfect, they hit hard and never flop, the sound quality is crisp and accurate, plus they are works of art and look as good as they sound. I love them and recommend them highly    Wawdy24 (August 11th, 2003) STRENGTHS: Accurate, Crisp, Clean, Hard, Body Shaking Bass. Turns Heads With One 12 (But I'm Getting Another). Easy Install. Box Saves Trunk Room (Getting A Custom Box Built Though). WEAKNESSES: Break in period is longer then I thought. Going to try 25-30 hours. Polk/MOMO needs to make the woofer protecting grill a little bigger (it gets annoying when the rubber on the cone is vibrating off the grill cover) REVIEW: I have had this sub for about 3 weeks. I owned an Alpine MRD-M500 which puts out 250 Watts RMS and a little over 900 Max. So I was a little disappointed when I first purchased the sub because, well of the low output of my amp, the bass just wasn't there. I just put in my brand new amp (Alpines MRD-M1000, which puts out the needed 500 Watt RMS 1800 Watt Max). The speaker hits very hard when you put a true 500 Watt RMS Amp to it. The speaker wasn't broke in possibly, because now I have to take it back and get a new one because the speaker became very hot, and decided to smoke. The only thing I could come up with was that the break in period of the speaker must be higher then I first anticipated. The time that I had this sub hooked up to that Amp, I was totally amazed at the output. Crisp, Clean, Hard, And Accurate Sound. What more could you want out of a speaker? Keep producing great products, and I'll keep buying them. Anyone willing to talk to me about Polk or any other car audio, feel free to IM me on AIM: Wawdy24    dca (July 31st, 2003) STRENGTHS: Hits very hard and i only have the amp half way up WEAKNESSES: NONE REVIEW: this sub whams and i love it. i always get a second look when i roll by with my 12. i only buy polk products because they are the best and they proved again that they are awesome with this slammin momo    Chase67 (June 23rd, 2003) STRENGTHS: Sound & Looks WEAKNESSES: Long break in period. To much power can blow sub REVIEW: I really like the way the bass hits and the crisp & clear sound. But it comes at a price. If you have to break this sub in for a long time before turning up with deep bass tunes. I had my First one for a total of 4 days. I got it hooked up to Fosgate 501s which does 500 RMS like the MOMO. The 501s peaks at 1500 the MOMO at 1000. I broke it in for about 10hours and turned it up about 1/3 volume with a low bass tune, with no bass boost from the amp and it blew. Hopefully this one does better I'm going to break it in for 20-30 and do the same test again.    Rashid (June 8th, 2003) STRENGTHS: You can roll with them like no other (sound amazing, extremely loud, hit hard) WEAKNESSES: nothing! REVIEW: Ive had these subs for about 2 months now, and i love them. They are simply the best i have seen for the price (although it is a bit expensive). I had a custom box made for it 2 weeks after i got them, and they sound even better with the new box! I reccomend this product to anyone who has the money.    tom (May 30th, 2003) STRENGTHS: hits hard... great styling.... easy install. WEAKNESSES: wiring flexibilty(but i only wanted one sub anyway)... looks too pretty.. im scared to damage it or scratch it REVIEW: all i have to say is WOW... i had a rockford 500s amp that i bridged into a kicker solobaric s10L7 the top of the line kicker square sub and it doesnt compare... i tested the mm12 out in my civic and it hit much harder... i ordered mines off of ebay for about $250 compared to spending about 200 for a 10" kicker solobaric and the box. with polk you get a 12" sub and a sweet box and a great grill. i can barely see out of my rear view mirror... everything blurs when this sub hits.... it sucks the power right up and begs for more.    Aaron (May 17th, 2003) STRENGTHS: best SQL of any sub ever made, also very loud WEAKNESSES: long break in period REVIEW: These are great subs. They hit very hard and very low. If you are one of those idiots that blew your subs in a month then you need to start breaking in your subs. It takes around 72 hours of use before these subs are broken in. You have to play them at a reasonable lever for 72 hours then you can crank them up. You can't just hook them up and turn it up all the way.    JM (February 17th, 2003) STRENGTHS: It sounded good for the average person, but not if your trying to go to car shows and show off. WEAKNESSES: didn't hit low and not even worth the money REVIEW: I bought one of these subs just to here what all the talk was about and and i wasn't to impressed with it. I have 3 Audiobahn alumx12 with a 2300w amp and i personally think that the MOMO 12 had no competition for even one of the audiobahn's 12. So I would suggest to anybody that is looking to get a system go audiobahn. In my opinion they are top of the line and have great sound qaulity.    Kenny (February 9th, 2003) STRENGTHS: Very clean bass, sharp looking, LOUD AS #@$% WEAKNESSES: When ever I play Song with low BASS, the rubber hits the grill causing a horrible sound even with the bass turned down it still does this, any song with higher bass vibrates everything in my truck loud ass hell, but I may have to try an Alpine Type-R I cant stand hearing it hit the grill, I'm running 1 MOMo on a Sony Xplod 760W bridged REVIEW: Loudest thing i've ever heard, other then a jet engine Kind of expensive, but worth it    Jeremy Gardner (January 26th, 2003) STRENGTHS: Such high quality! WEAKNESSES: No weaknesses that i can find! REVIEW: These are some of the best subs ever produced.    Jeff (January 6th, 2003) STRENGTHS: A little loud between 40-70hz. Looks nice. WEAKNESSES: Where to begin?? DOES NOT HIT LOW..........I REPEAT, DOES NOT HIT LoW!!!! Single voice coil design gives no wiring flexibility. Sounds muddy, cant handle more than what its rated at even though Polk's website says its better to give a speaker more power than less power(which is true with any other speaker than the Momo). REVIEW: I think this sub was specced out with just a bunch of garbage. Respone down to 20 hz, in its dreams. The true response which i discovered using my Bass Mekanik cd is around 30 hz, which the sub still doesnt play reasonably loud. I had 2 of them wired in parallel enclosed in the box it came with powered by an MTX 81000D. Both of them blew and the entire box filled with smoke, which mae my car smell like the worst stench in the world (burning voice coils are definitely not cool). I was extremely ballistic after this happened, i was truely stunned. I had a lot of faith in this "500 w" $350 dollar sub which i luckily got for its true value of $99 through employee discount at my work. After this i bought 2 Alpine Type R's and but em in a dual 12'' sealed box. After i heard them, i almost cried at how low it hit. The Type R's blew the Momo's out of the water. Type R's are rated 300w RMS and Momos at 500w RMS, and i sent more power to the Type R's than i did to the Momos and they just sucked it up like a dying man in a desert. Price of Type R by itself, now $159 at customer price for sub alone, Momo for 12'' by itself, $249.....I dont think so. I am really ticked off at Polk for evening manufacturing a sub like this, i wouldnt be as mad if the specs were actually true because then i wouldnt have bought em. This isnt the worst sub I've heard, but if u are looking for something that hits low, look elsewhere when u consider the Momo. It's not even the lows, the Type R's was sounded cleaner, tighter, and more likelike; the Momo is basically a sub that only knows how to play 40-70 hz and thats all. Now to the point of Polk's "technicians." I emailed polk saying that i played pink noise through the sub to break it in a little and then it blew and this is what they said: Hello Jeff, Thanks for contacting us. I believe you made one fairly serious mistake, you can't use steady pink noise at those high levels. The results are excessive heat which is going to damage both the speakers, enclosure and potentially your car. Speakers, anybody's speakers, produce heat as they generate sound, in fact a speaker is a more efficient heat generator than it is a sound producer. An engineer once described a speaker as, "a heater that happens to produce sound", meaning that mechanical friction produced by a moving coil inside a voice coil gap is a very efficient way of making heat. If you were, in fact, producing more than 400 Watts of energy, that is equal to over one half a horsepower, allot of power, correct? The difference is that the nature of the steady state pink noise is completely different than what happens when playing music. Music is completely random, constantly changing, never asking for peak levels for more than a 1/4 of a second. There isn't the chance for building up the tremendous potential for heat, like thesteady pink noise you were using. .......is that the biggest bunch of BS ever. Now the subwoofer producing a lot of heat is true, but that other crap he told me is just ridiculous, do they think I'm stupid? Simply i am very mad at Polk for making the Momo sound like it can take out any other sub(i serously heard a Sony 12'' Eplod hit lower than the Momo, no joke hahahahaha) and also mad for the completely absurd email they sent me. I dont know what they were shooting for when they made this sub because it doesnt stand above most subs in SPL AND SQ, especially at $350, you are only paying for what u pay for when u shop at Abercrombie...................the name(MOMO). P.S. This review is the truth and will tell people what they are truely getting, so please put this review in the bin. I believe i have the right to be heard because of what i went through and dont want someone else to go through the same stuff.    Ed S. (December 26th, 2002) STRENGTHS: Power handling with Deep,solid,clear bass!! WEAKNESSES: HAHAHA..there are none REVIEW: All I had to do was hear it once at the store..it was mine. I'm getting 1 or 2 more. After hearing this sub I had to change the rest of my car audio over to Polk....Best sound and performance out of any other sub and car audio I have seen    Brett G (November 30th, 2002) STRENGTHS: Needs a high powered amp which is costly, but worth every cent. WEAKNESSES: I would recommend this sub to anyone. REVIEW: The clearest bass i've heard from any sub yet,and cool looking too!    justin loos (October 25th, 2002) STRENGTHS: pounds WEAKNESSES: It will sometimes hurt your ears it hits so hard REVIEW: This is the best sub i have ever had. I cant wait until it breaks in so i can turn it up. That sub will pound. I am going to buy 1 more momo.    garrett shuck (October 6th, 2002) STRENGTHS: beautiful design and superb sound WEAKNESSES: none what so ever, perfect size, shape, sound, and style REVIEW: Just bought one the other day for 230.00, thanks of to where i work. It hit harder than my JL 12, even with the same 300 watt bridged at 2 ohms.    Mary Conway (September 30th, 2002) STRENGTHS: It was strong while it lasted, and turned many heads. WEAKNESSES: After only a month my Sub stopped working completely. Another problem that I encountered was the buzzing noise the speaker made when the rubber and plastic hit together when the volume was even just a little bit high. A noise that all audio enthusiast dread. REVIEW: I loved the Sub (MM12) the first month I had it. It was powerful, hit hard, and turned heads everywhere I drove. But after only a month of regular use my sub stopped working. I spent $350 on a sub that only lasted a month, which doesn't look good at all.    David (July 26th, 2002) STRENGTHS: it has the best strength i have ever seen in years. WEAKNESSES: there are no weaknesses that i can see or hear. REVIEW: I just love this sub, it put out the best bass i have ever heard in a long time. Iam going to get me another sub to compleate my polk system.    Joe Bob Riggs (July 26th, 2002) WEAKNESSES: WAS RECALLED! REVIEW: Well the other day, i would have been unwrapping my new polk/momo 12" sub, but when i had gone to the store to pick it up, they told me that they needed to be taken off the market, for a recall, and would be back in september. And still i see it on your website to be purchased. What exactly was the reason for this recall, and why is it not effective for the speakers on your website? Polk Response: Polk Audio's first concern is the long-term satisfaction of our customers. For that reason we have decided to temporarily halt shipments of the new Polk/MOMO subwoofers - both the enclosed models (MM10 & MM12) and component models (MM104 & MM124). An unacceptably high number of units experienced a failure of the glue bond that secures the spider to the voice coil former when played at a very high volume level. All Polk/MOMO subwoofers in the hands of retailers are being returned to Polk Audio. We were caught unaware by the problem as prototype units fully met all torture tests and the production units passed the industry-standard EIA-426b power handling tests. We understand the reasons for the failure and have devised a test that will prevent future manufacturing defects from getting out into the hands of customers. We have absolute confidence that future production units will meet or exceed all performance specifications and be able to play very loud with full Polk Audio sound quality. At this time our best estimate is that we will have perfect in-spec units back into dealer warehouses in September. If you have a new model Polk/MOMO subwoofer and it is working, you should keep using it. The odds are that the woofer will continue to work fine. If you want to replace it with a new unit in September or if you have a unit that is not working correctly, contact your Polk retailer or Polk customer service at 800-377-7655 or email polkcs@polkaudio.com). These models appear on our web site because people want to know about the products whether or not they are immediately available. These units are not being offered for sale on this website. We do not sell our car speakers direct to consumers. This notice applies ONLY to the new model MM10, MM12, MM104 and MM124 products. Older Polk/MOMO models MM100 and MM120 are not effected.
