Box

[PokerBlakeB]

vent would be 3" wide and 15" height

[Ray]

would have to be wayyyyyyyy to long

go sealed or 1 vented

[PokerBlakeB]

what if i made it 36 Length x 17 1/2 depth x 16 1/2 height giving it 6.015625 and each sub has 3.0078125. Could i port 3 inches in the middle and like 14 inches deep? I really want to use both of these 15 l7s i bought and the bxi2608d. Want to get the fullest potential out of them and i thought venting would be best. Is there any way possible?

Output increases by HEAPS by porting.

Either go sealed, find more space or lose a sub. Those subs need like 4 cubes each, although since you're slightly overpowering them (I think? 2608 makes what, ~2200w?) a small box isn't a terrible thing.

All that said, 6 cubes is way too small unless it's a pure SPL setup.

6.01cuft is perfect for both sealed 15 l7s

6.01 is the biggest box they recommend for 1 15 l7

~4.5 is the best sounding cuft for 1 15 l7 ported

if you subtract the port volume ur volume goes from

3.75*15*14= .46cuft

6.01

-.46 (port disp.)

-.4 (subs disp.)

5.14cuft.... this would suit two 12's ported but not 15's

either both sealed or 1 ported

[PokerBlakeB]

when making a sealed box for two 15's do u leave the whole chamber empty. Or put a divider inbetween?

[Decaf]

if you dont use a divider use some 2x4 for bracing

doesnt really matter as long as the box is airtight and has no flex
