New SR subs

[hrdhtdvr]

Has anyone tried out the new SR subs? Not that I am going to buy one, but just wondering how they sound compared to the Momos and how you like them.:D Also, what are you using them in? (truck, car, etc...)

[MacLeod]

They just now started shipping them if I remember right so, probably, nobody has one yet. My local Tweeter doesnt.

[Greg Peters]

The Polk dealer I went to in WA had some 10s and 12s on display as well as some stock. The place was being renovated when I was there, and the salesman had to hunt before finding they were all sold, displays included.

They are supposed to be pretty great sounding, though. These guys have done some installs with twin SR subs already (and say they get pretty loud, too).

If I can hear one first, I'd consider tossing my 10" for an SR 12. Ideally, they'll have a 12DVC in a sealed box I can try out in the car next time I'm in there.

The sad thing is I've had 2 for a while and haven't been able to do anything with them because I haven't done the amp install blah blah blah.......

Some day.......

What are you waiting for?!? Its not like you have a job anymore!

[DSkip]

the dealer down here got a few in i saw about a month ago. theyre massive and look amazing. if i had an income right now i would definitely have those and the sr6500s. the guy basically sells them wholesale.

[heXtant]

they are for sale on cardomain for 350 a piece. the 10s are 300.

i found 2 sr12's for 555 that i might just buy.. still trying to decide.

[brettw22]

What are you waiting for?!? Its not like you have a job anymore!I was originally going to build the box as a dual sub box with a partition, but decided i wanted to cut it in half.....

My friend has a mitre saw, but it doesn't extend so i'm not getting clean cuts for the angles, so either I"m going to buy a table saw or rent one to get the pieces cut so i can be more consistent than just trying to freehand with a jig or circular.

Youre not a real car audio dork until youve built your box with using only a jigsaw on the tiny 6' x 6' deck of your apartment! ;)

what??????

[xtorted]

I have one of the DVC 10s sitting in my living room waiting for my enclosure to be finished. If I’m real lucky I’ll be able to test it out this weekend. At 25 pounds I had to add a few extra layers of fiberglass to the front just to make sure it'll be ok, that set me back a few days. I didn't realize it was so heavy compared to the 12" momos I had (the cast aluminum basket ones).

[brettw22]

I have 2 of the 12's

What is the face of your box made of that you need to reinforce with extra layers of fiberglass? I'm using 3/4 MDF for the box, and don't anticipate any problems in keeping it supported.

[audiobliss]

I imagine it was fiberglass the start with, but just wasn't thick enough to support such a substantial sub.

[Greg Peters]

Well when you get the time...be sure to say how you like them on the forum (so the rest of us can start saving up the $$$).

Maybe someone can email you every hour until they're installed, as motivation for an update sooner rather than later ;) .

[1996blackmax]

Would be interesting to read about how they sound.....

It's all fiberglass, with an MDF ring. I just didn't expect such a heavy sub so I figured I got it all out why not add 2 more layers of fiberglass just to be sure.

The enclosure isn't all that big, it just makes the .66 cubic feet of air space polk recomends, but after all the time i'm putting into this i don't need to hit a bump or just be driving down the street and then all of the sudden...crack. I went over kill on my last box, the same here wont hurt :)

I must go now, gotta rewire the back of my car now so I can hook my amps up.

So I guess that since they weigh in at 25 pounds, they would not be too well recieved by a MTX thunder form that is made out of plastic. :D

[MacLeod]

The MTX Thunderforms are a little tougher than your run of the mill plastic enclosures.

But that doesnt mean Id want to run an SR in one.

[Thom]

The SR's are quite an improvent over the Momo's, or the old db's, for those that were so fond of them. The Momo's are nice subs, for the SR's to poop on.

They'll work in enclosures as small as the current subs (.65 and .85), but you'll get better low end in a larger box (like 1 and 1.25). And they kick ass in ported boxes, but be prepared to give up even more space.

It wouldn't be a bad idea to use a 1" (or thicker) baffle to mount them to, they're quite a bit heavier than any woofer we've ever had.

They're a couple inches deeper than our other subs, so they wouldn't likely fit to test the theory...

Since you seem like you've had some time listening to the SR subs, how would you describe them? SQ? SQL? SPL?

Are there any similar products from competitors (that we might be more familiar with) that the SRs compare to in sound, yet also "poop on"?

I see that these have a fairly high rms power rating (700 watts continuous), so do you think they'll need all of that rated wattage to sound their best? I just upgraded my sub amplifier (but it's only 600 rms) and would hate to have to upgrade again right away should I get an SR124 DVC.

[MacLeod]

Polk Audio is all about SQ so I would assume their top of the line subs will be as well.

Id also be willing to bet that 600 watts would be ok.

As far as competitors, they designed them to match up to the W6, which is one of the best SQ subs ever so that could give you some idea on what theyre like.

[1996blackmax]

There are subs out there that I would take over the W6 any day of the week....

[MacLeod]

Good for you.

I kind of figured they had the W6v2 in their sights when I saw the promo shots of the SR subs. There are some design similarities in the styling of the cone and basket- not in a knock off kind of way, but in a heavy duty built excursion capable kind of way.

I am very familiar with the W6s, and am sort of using them as a benchmark. I just didn't want to say the JL word. Oops.

[1996blackmax]

I know it is.


I am also not the only one.....

Dont worry about it. There are only a couple bandwagon JL haters around here.

[Meeks32]

Sorry, but for $400+ this driver doesnt look anything special just from a quick look at the t/s spec's. 16mm of xmax is a joke now & the Fs of 30hz isnt that good. For the price I would much rather have one of the new drivers from TC sounds www.tcsounds.com/tcproducts.htm

[MacLeod]

You may be the only guy Ive ever met that can tell how a sub sounds from the specs.

How bout ya wait til you hear one before you start trashing it.

[Meeks32]

Sorry, I come from the DIY Ht sub area & looking at t/s spec's is just habbit. Im sure they wont sell for the $400 retail price but I do stand by my comment of buying better for the money from TC sounds. For less money you get a sub with a LMS motor & double the excursion, & tc subs are some of the lowest distortion subs you can buy.

[exalted512]

and everyone knows that x-max is a great deciding factor when buying subs:rolleyes: :rolleyes:
-Cody

[MacLeod]

Ill stick with my Polk.

Im holding my own and beating guys with Focal, JL and Quart's. Not too bad from a measly single 10 with half the power the other guys are using.....not to mention half the price.

[Meeks32]

If the sub is in a sealed enclosure, yes its important since excursion increases 4x everytime you drop 1 octave and without the aid from a port in lower frequencies, the driver is left to do all the work. I know its not as big of a deal in a car when you get tons of cabin gain, so Im just nitpicking. Im not trying to start arguements since im a huge polk fan myself, but I was just hoping polks entrance into the "supersub" market would be a little bigger & badder. While im sure this is a great sounding sub, you could always just buy a new Dayton High fidelity or ID idq for much cheaper if thats what you want.

[exalted512]

With a power handling of 750 watts, I dont think this sub will have any problems getting loud for what a sq system needs to do.
-Cody

[MacLeod]

And, as mentioned, this is an SQ sub. Its not supposed to be cranking out 160 db's. Its about sounding very good.

As for getting low, my 2104 has only 18mm of Xmax but yet can hit the 25 Hz note in one of MECA's test songs. Thats pretty good considering its in a box .10 smaller than its spec'd for.

[1996blackmax]

I only know of one person here who truly does not like JL, who is the other Mac?

I think that Xmax you are claiming is mechanical, which is misleading I think. My TC Sound sub from Soundsplinter had 20mm of linear Xmax, but the mechanical limit is actually more than that. Take for example a test done on the DB's, the mechanical xmax was 25.4mm, but the linear was only 7.5. Your 2104 only has 9mm of linear excursion. I understand there is more to a sub than just that, but if you are going to compare, use the same measurements. Linear vs linear...

TC Sounds makes great subs, and like it was said, some of the lowest distortion producing subs around.

Image Dynamics also makes very nice subwoofers here in the ole USA.

Well I now have my SR104-DVC installed. It's been in for a few days now. Haven't had a chance to mess with my settings on the amp, or even my radio. Right now I’m stuck with an OEM radio with NO EQ settings :eek: . I'm also waiting on my new amp, which will give this bad boy the power it needs, but the amp I’m using for now is putting out 350w @ 2ohm. And boy does this thing sound amazing. I had one of my momo 12s installed temporarily (the one that came in the enclosure, they were on sale for about $100 cheaper then the ones without the enclosure, was a no brainer when getting them) while I started switching everything in the car over to aftermarket and compared to the SR the momo sounds like trash, which was shocking since for 2 years those momos put out so much better sound then most other systems I heard. I'm very pleased with this sub so far. The one thing I noticed was with the momo, even when moving it around to find the sweet spot, it never really seemed to fill the car. It just kind of sounded centralized in the back. The SR sounds like it’s filling the car, which is nice because you don’t seem to hear bass from the back like with the momo.

As for how much air space I have...I shot for the .6 cubic feet the manual said, but I was off by a little, I forget how much but I got as close as I could which wasn't bad for not measuring anything. I’ll be making a new enclosure at some point towards the end of the summer, I need to make the front a little different to blend into the car more as well as give me a little more air space.

Here's a link to part of my install so far, it's a HUGE work in progress... clicky (http://forums.fourtitude.com/zerothread?id=2706676)

[Toxis]

wow... so excursion tells you the sound quality of a driver? Someone should tell MB Quart, Focal, Dynaudio, Morel and all the other sound quality subs out there that don't need to move a lot of air to sound good. Guess output still wins in people's hearts... so sad.
