I decided to do some comparisons to help me decide what my favorite type of sub/box is - my existing Hutchinson 10" in a small-ish ported box (about 1.3 cu.ft), vs two 12" Brahmas in a small-ish sealed box (about 2.3 cu.ft), vs one 15" Brahma in a large sealed box (about 3.4 cu.ft).
They will get 2,000 rms @ 2ohm from an Mmats 2000.2, and will be tuned individually with Dirac.
Below is the box being built for the two 12"s, and next I'll build the box for the 15". As always, 3/4" BB plywood and NO drywall screws!
The Jeep's tailgate has an angled protrusion on the driver's side, so I chose to put 45s in both side to give it symmetry:
I know, I know, I didn't miter the joints properly! Lol
This box doesn't need bracing as the individual panel runs aren't very long, but I decided to have some fun with scrap plywood.
That's where I'm at for now...
