I had two different designs done by two totally different designers. Well, the trouble that the box depth (Box A) is a bit much for me to give up on one, and the other (Box B) seems to be too small. Not to mention that it has no bracing internally.

Box A (Was designed to have a plexiglass front)
Specs on this box are 36"(W) - 17"(D) - 16.5"(H)

Box B (Basic dual box)
Specs on this box are 36"(W) - 12.5"(D) - 15.5"(H)

Neither box has a double baffle for the subs, but I normally go with internal bracing. Any help would be appreciated, as I really don't know which design I should use.

Is this box ported?

I don't see a port opening but it looks like there is a port wall inside?

Also no one can tell which one is the right one if we don't know what your looking for.

Post up what subs you are using along with desired box vol and tuning if going ported.

Yes, that box is ported.

Subs are 2 Polk SR 10D4's.
Max dimensions are:
W - 36"
D - 17" (Less = Better)
H - 16.5" (Less = Better)
Desired tuning 30-33hz......

the second one is 2.32 cubes after port displacment

the first one is 4.48 befor any displacment being i cant tell what the port is

with those subs i would shoot for 1.3-1.5 cubes per sub at 32hz

If you are not going to use the plexi, i will re-design it to accomodate the change, the only reason i had to do the vent that way was due to the Plexi.
