Hey, im looking at building myself a 12" subwoofer for my home theatre room but i need some suggestions on drivers?. what i want, is for this sub to carry some quality behind it, and be able to perform well in a theatre application. ie. fill a room with authority and go down to 20hz. im looking at the Brahma (mark III)... or a maelstrom? tumult would be perfect but the brahma is already pusing my budget. how about the tempests? (reason why im so clung onto the adires is because they are easy for me to get my hands on, and i hear good things) perhaps you guys can throw out some suggestions for me to research.
