I bought some 21x21x25" enclosures (thanks to member forin)

Theyre dual opposed 15" enclosures. They should have approx 2.5 cu ft of space for each woofer after bracing and displacement of the woofer itself

I need some woofer suggestions.
>i already bought two alpine sws-15D2

T/S: http://support.alpine-usa.com/products/documents/OM_SWS-101215_D4_2.pdf

Their cone is cheap and overall feel is pretty cheap too... but they were $300 for the pair from an authorized dealer so i figured might as well give them a try.
>I am also looking at Sundown SA-15 D2

T/S: http://sundownaudio.com/index.php/products/subwoofers/item/sa-series.html?category_id=2
>The alpine SWR-1522D look nice except theyre ugly

t/s: http://www.alpine.de/fileadmin/user_upload/manuals/car_audio_manuals/SWR-1542D/OM_SWR-1542D_EN.pdf
>I have a chance to pick up two of these audiopulse 15"... i assume theyll work fine in 2.5cu ft?

Please ignore price for now, i guess what im most interested in is if you think ill run into any problems using any of these subs in 2.5cu ft, just so i know which ones NOT to buy.

Dual Dayton DVC15's would work in that enclosure.

My Dual 18" LLT subs 120dB down to 10hz

How much power are you going to be running? The Obsidian 15"s will work. They're only $160ea, and you can get them with D4 VC's.

Ricci has an SA15 that he is testing currently, results are coming. He said after the T/S spec run that it looked quite promising. If you aren't in a hurry, the results may help your decision.

I will say I beat the crap out of 4 SA12s, and they are really great performing.

Do the obsidian work in 2.5 cuft of space? They're tempting. The sa15 looks super robust as well I trust them to be good drivers its just whatever driver does the best in a small enclosure. I just bought an ashly klr3200 and I have an nu3000. Guess I'm using that for power

The KLR3200 is a great amp.

I ran an Alpine Type S subwoofer for a couple years back in the days. It sounded good in a sealed enclosure and never had any problems with it.

I sent you a PM in regards to the audiopulse. Good luck with your build.

Dual LMS-R15 might work. In that size you'll get a sub .9Qtc system which isn't too bad. Most people won't go for it cuz it sounds high but it has perfect excursion control and you can put 4-5kw of power into the box with no issues. Now if they both could physically fit in there... probably. wink.gif

EDIT: G'damnit. Made a mistake and had selected four drivers in that space. Le sigh. I do make mistakes every once in a while. wink.gif

Sooo...two LMS-R15's model VERY well in that 5cuft size. A perfect .7Qtc so that's good, yes. 1,000w input per driver is a good optimal amount.

My Dual 18" LLT subs 120dB down to 10hz
