[QUOTE="thylantyr, post: 4014285, member: 560358"] Dome tweeters aren't ideal for line arrays but if you can get CTC to 1.5" or less, it can work well, people have done it. But, if you did find a dome tweeter that can do 1.5" CTC, most likely it's small and it's performance is limited, ie Fs is high, which limits the ability to get great sound at a lower crossover point. re: (4) AA Avalanche 15's in 11 ft^3 sealed on a QSC PLX3402 (3400 watts RMS). My HT has bass. . . I have those PLX amplifiers. Check the QSC spec sheet, those amps won't do 3400w rms for sub duty as that power rating only applies to 1khz tones. I tested mine at 2kw rms, 20hz, 110VAC input, then the amp went into thermal protect shortly. Four woofers + one PLX, expect no more than 500w on each woofer if the wiring is proper.
