I built a fiberglass enclosure for a 15 and it only has 1 cubic foot of air space....Does anyone know of a 15 in subwoofer that would sound good in a small sealed box?

Each of my IDQ's see 1.35 cu ft, but I would imagine they would still work in a smaller enclosure, its just a matter of losing some of the lower frequencies.

Isnt building the box something you do after knowing what your going to use? get some pictures of them, I love seeing nice FG boxes. also as XS said, those w6s are good in small boxes.

i have researched some of those idq's but man...are they expensive. Do you think a 550 watt amp would push them and still make them pound in that box if i stuff it full of polyfill and reverse mount it so that the sub doesnt displace any more space?

My cousin swears by JL so I was also looking into one of the w6's. Do you know where i could find a used one for cheap ? Thanks for the help so far fellas

I doubt you are going to get a good response from a 15" sub in a 1 cubic foot enclosure.

The enclosure is about 1.2 cubic feet I rounded down just to get an estimate of what options are out there...

If you can find a 15W6 (now discontinued) you could put it into a 1.2 cuft sealed enclosure. You'll have a really boomy, peaked response around 70Hz and an Fb around 50Hz, with not much deep extension (at 30Hz you'll be down as much as 12db.) But sure, the woofer won't care. They have 400 watts continuous power handling. ------------- Support the12volt.com

I went the cheaper route and got an Octane-R 15, Any comments about this sub?

It's a big box woofer. Your Qtc. in that enclosure will be 1.2 which is really high. Your response is going to be very similar to what Dyohn said. The sub looks to have a pretty high impedance. The Q is also pretty high. It does have a pretty good Xmax at 14mm one way, as well as a decent sensitivity at 89 dB.

You may be a good candidate for a Critical mass sub. www.criticalmassaudio.com aparently they make good subs designed for ultra small enclosures. ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

I'll look into that alpine guy...Thanks for all the help so far everything...I have one question though for Steven Kephart...Im not to familiar with all the technical terms, in your opinion, is the octaneR15 worthwhile or not?

You have two threads going with the same question now, so I'll close this one. I doubt you will find any 15" speaker that will sound good in that small an enclosure. Physics gets in the way. :) ------------- Support the12volt.com
