Infinity vs Polk

[PoP_N_FresH]

Hey, i was wondering which subs would be better to put in a Dodge Durango.(big an spacious)

Im am currently looking at the Infinity Kappa 12DVQ and the Polk Momo mm124. i want to put two in my durango and i would like some help to make my desicion.

Also i was wondering what box(s) would be the best for these subs. bandbass, dual bandbass, sealed?????? money isnt a thing on these because i got hook ups. please help.

box - sealed will give you the tightest most 'musical' response, but will require the most power and will the be quietest (relatively). you gain volume and lose precision as you go: ported, 4th order bandpass, 6th order bandpass. the bandpass boxes pound like mad, but every note sounds the same IMO. in ported and 6th order bandpass, you absolutely must use a subsonic filter below the tuning frequency, else u cook ur subs real quick. 4th order and sealed it's not so important, but not a bad idea.

you guys(gals) know where i can find a cool dual bandbass box for infinity kappa perfect 12's or momo mm124's?

[97FordExp.XLT]

If I remember correctly Polks are designed for sealed boxes.

You don't want to put the MOMO's in anything other than a sealed box. According to Polk, the suspension couldn't handle it. Sealed boxen sound much better anyway.

I have a pair of these, in a sealed box and they slam! I'm suprised at how much excursion they exhibit in a sealed enclosure. I'm using a relatively cheap Kenwood amp (7201) bridged at 460 watts RMS.

I haven't tried the MOMO's, so I can't comment on them.

BTW, I've had 12-15" subs in my car since the late eighties.

Hey think if i run two of polks c500x1 amps to two Infinity Perfect Kappa 12Dvq's it will do the job?

[PolkThug]

Doh! I don't have the DVQ's I have the DVC (dual voice coil).

[neomagus00]

yeah, it'll power them quite well. for these subs, any kind of box is acceptable. sealed will still sound quite good; in any case, make sure you follow the guidelines in the manual as to box volume and associated insert size.

you can put momos in a band pass and it wont hurt them
i wouldnt b/c of SQ issues, but theyll be louder than a sealed box

Yeah, the Momo's can work in a bandpass box, but we prefer one of our design. Since aftermarket bandpass boxes aren't set- up for any particular woofer (and the ports are usually too small), we haven't been happy with our woofers in any bandpass box that we didn't build.

[PoP_N_FresH]

For the mm124's how much of a difference is it between the sealed and bandbass? Cuz i want my subs to hit, but if they are going to sound bad in bandbass i dont want to waste my money.

[exalted512]

well unless you get the box built to polks specs, its going to sound like crap
either way, i wouldnt get a bandpass, id stay with sealed

k thank

[startzy]

well what id do if i was you is buy the polk momo put it in a sealed box break it in and enjoy your bass.ill tell you what man polk knows how to make subs that put out some serious bass iv got 1 polk gnx 10 inch in a sealed right now couse i scred my other 1 up but anyway i blew this dudes two rockfords 12 inch subs away and they were in a ported box.polks the way to go

[PoP_N_FresH]

how would i bridge my amps then too my two subs?

[neomagus00]

um... okay, to bridge an amp, you connect the negative terminal of one channel to the positive terminal of another channel. you can bridge a two-channel amp to one channel, a 4-ch to 2 ch, etc. if you have, say, two 4-ohm subs and two amps, you can bridge each amp to one sub. if you've got some other combination, cough it up and we'll figure it out. this includes what kind of amps you've got (links are cool) and what subs too (links are cool).
