quick change to the demensions ..i realized the two 6.5s wouldnt fit in the enclosure right with only 13 inches in width so here are the new measurements for the three chambers

chamber 1 9.75 x 14 x 19.9688 (31/32)=1.57739652777...
chamber 2 9.75 x 11.9375 (15/16) x 19.9688(31/32)=1.3450122178819444...
chamber 3 9.75 x 8 x 19.9688(31/32)=.901369444...

promise no more changes
