This is a highly modified discarded Zen OB cabinet with a modified side fire 12 inch sub.
I always liked the TB 1808 and love open baffle sound. To fill the low end, I knew I would need to add a sub of some sorts. You could include any of the easily accessible 12’s.
Tang Band 1808
GR Research 12, with PEQ 370 amplifier
OB upper, with a sealed lower 1.75 cubic foot cabinet.
Front baffle is 6/4s maple boards laminated together and screwed to the back box. The side fire is in a 3/4 mdf box with a 1.5 inch side baffle. The amp is cut in to the back of the lower chamber.
None, but I built modified amp/rca high pass filers specific to my amplifiers ohm rating.
