Box for 15 DD subs

[2002tahoe 10+ year member]

Would a box with the dimensions of 2(ft)X2(ft)X3(ft) be enough room for 2 15 inch DD subs?

this is what you should go by http://www.ddaudio.com/dd/caraudio/enclosureInfo/boxSize_hiEff.asp

be sure to tune the box to 40hz and build it after DD specs. they know what they say. i tried other tunings but 40hz is the way to go, even the lower end output will be better than with a 35hz tuning!

3.5 - 4 cubes each 9515 is OK.

ok so it says "15"(3.0-4.5)" so if I am correct 2 by 2 by 3.5=14 sq ft. Now I could be wrong becuz i **** at math but that would be ample amount of room then since 1 15 inch requires three to four and half sq feet so naturally 2 15 inch woofers would need six to nine sq ft. Correct?

seems a bit large to me they recommend 3.0-5.0 cubes for one which is 6.0-10.0 cubes for two and that box is 4 cubes too large

Ok so if my audio dealer is saying that i need 2.5 by 2.5 by 3 then he is insane

im not saying he is insane im sure its been done before i was just pointing out that it is 4cubes larger then DD's listed optimum....it would help if you could get more specs on the box tho

allright time for my input ont he 9515f's.

depends on what you're going for,

if you want SPL....give each one about 3-4 cubes after displacement each.

if you want some big boom, 5-6 cubes after displacement...

and if you want just insanely low crap, 6-7 cubes.

buuuuut....if you go for 6-7 cubes dont throw more than 2kw to each one because they wont last long in a box that size with that power...

personally i enjoy 5 cubes after displacement per sub, which is what mine are in now, peaking @ 35hz...its loud, and plays as low as i want it to with no problems. how much power do you plan on givin?

you also have to figure displacement of the wood, port, subs, etc... you can't just figure your external dimentions as your volume.

I was planning on giving each sub at least 2000 watts a piece iff not more. Becuz the Rms is 1500 and peak around 6000 so I was actually thinking about giving more around the range of 3000 to 5000 per sub iff I end up having the money for it. What amps would you guys recommend for this type of output?
