Hello. I am making a 4x10 sealed 2 chamber bass cab in lexan/polycarbonate. How much volume does each chamber need? Are there any technical info on the speaker elements that say how much volume each element needs? Or is it a specific volumnumber for all 10" speaker elements? Does anyone know how much volume there is in each chamber on 8x10 ampeg svt? Because then I could just copy that volume. What is most dangerous? To little volum or to much? Thanks.
