Would a single 12" cvx sound good in a 2.5^-3^ tuned at 32hz? Which would be better at smashing the lows but still be able to play some of the punchier frequencies 2.5^ or 3^ at 32hz. Any other recommendations are accepted.
I listen to rock rap and reggae if that helps

It will get plenty loud, but I don't know how well it will handle "punchy" notes. I am sure someone else has more information for you, but I know for a fact that that size and tuning will help get low.

The free plans are awesome. Moe made those. Any plan you see that is 2.5 @32 hz will do, just make sure the height of the box is big enough for a 15".

but the plan does not account for the sub displacement?

He has a 12.... :/

24"L x 17"W x 14"H ( W meaning Deep )

Port - 4"H x 4"L x 16"W ( W meaning Deep ) ( Port on the side, speaker in the front ).

Yes the plans do account for sub displacement.
Many years ago Moe used to design and build for people on this forum. He doesn't come around as often but he knew his stuff.

Oh yeah, reading>me I thought I saw a 15".

so is this is 2.5^ at 32hz accounting for 1 cvx?

you may be right but how could it account for the displacement when every sub is different?

if someone could figure out how to add/subtract the sub displacement for 1 12" cvx from say this box http://img29.imageshack.us/my.php?image=25cubes32hz3125sqin0zp.png and give me the new dimensions with the sub added that would be great. the sub takes up .63^ft i beleive. let me know if that doesnt sound right.

Not all subs are the same, but in general the amount one 12" displaces vs. another different 12" is TRIVIAL. It really won't matter it is like .01 or .02 difference.
Oh and the sub is not going to take up .63 cu. ft. it is more like .17 cu. ft.

alright i understand, but it doesnt say that that specific box is for a 12" sub.

alright so let me just clarify that this box http://img29.imageshack.us/my.php?image=25cubes32hz3125sqin0zp.png WILL work and will not damage my sub provided i have the amp and sub set up correctly?
