Each one is made out of 1/2" bamboo plywood. Internal volume is 13.8 liters. Tuned to ~47Hz with a 1" diameter by 1.1" long port.

F3 is simulated to be 40Hz and I believe it. Haven't measured it yet though.

The baffle is relatively wide to reduce the effects of baffle step. There is no BSC or any filters in this speaker.
Just 10" of supra ~16 gauge wire between them at the terminals on the back.

Internal dimensions are all golden ratio.
