i have audiopipe txx bdc4 15s currently installed but got a little to rowdy and blew one up giving a demo, i also have a set of dc audio level 3 15s that also have one blown sub due to it unloaded when 5 of the screws broke off, im really debating on which subs would be better to rebuild. they are going in a ported wall enclosure at about 7.5 cubes per side only putting 1500 watts a peice to them for short periods of time during demos. any input would be greatly appreciated
