If in the vented box of 50lt, you place three vertical braces thickness 3/4", and two horizontal braces (full sheets with 2.5" holes)how much would you loose in internal volume? I just did that, and result was devastating! Bass was virtualy GONE! I ripped all out and realised i had to compensate in size of the box! But for how much? Thanks to friendliest forum around!Paul
current size: 24 x 16 1/2 x 11 11/2
Thanks again!
