maybe something like a cubo 12. nothing too crazy going on i don’t think

look into nick biotecs coffin bins. there's a long thread on them here.

if you're looking to go to 450hz or whatever like the plugged 12 in res 4s, straight is one fairly simple (but not that practical) way to go.

the cubo 12 seems double ventilated, no bandpasshorn. the coffin bin is 15" ?
