Thanks everyone for the help! I contacted soundstage and I talked to tech support but they were not much help since they don't make powered towers anymore so they needed a few days to look them up. So I went to visions and talked to a sales guy who owns a pair. he said don't use the LFE in. Now I have them set to small and crossover at 80Hz and they work great! The gain control now works on each tower so I have four eight inch subs in my mains. Next question is sub placement can I ask here or start a thread in the sub section?
