41.5" x 17" 20"
external and internal mdf bracing
1/2" threaded rod brace
fiberglass resin on inside
no corners on the inside, resin fixed that
all external edges rounded off
3 interchangable ports each tune the box to a different freq.
-~46.5hz (spl port)
Ports bolt in w/ t-nuts hammered into the inside of the box. Closed-cell weather stripping is on the port baffles to stop any chance of a leak.
This box was in a extended cab silverado and peaked at 49hz w/ the SPL port in. The hole for the sub is cut for and SX15, but could be re-cut for an L5/L7 if needed. The box is wired w/ 12ga speaker wire (blue and silver).
I competed regularly in USACi comps w/ this box. Max i got was 148.6dB, but i saw 148.2dB-148.4db on average.
This box is built like a tank...glued, screwed and counter sunk.
internal w/ resin
a lil vid w/ the 31hz port in
if anyone is interested, i can put up more pics.
MAKE OFFERS! (no low ballin please, this box has ALOT of work in it!!!)
