Not that I have to prove my insanity, but the new plan is four PL700's. Two WOPL'd 700 series II's will drive the MF and HF line arrays. No question that 400 WPC is overkill for the plannar tweeters but there are 8 plannars at 80 Watts max each, per line array. Besides, I like the PL sound. The plan is to use two more bridged 700B's to drive the LF's. Pictured cabinets are copies of JBL cinema subs but built with 1" MDF and internal cross bracing. The cabinets weigh 171 lbs each. I used RCF drivers (97.5 db/w/m) rather than JBL (99 db) The drivers claim 1500 Watts "AES standard" and 3000 Watts peak power handling....1.5 db less efficient but approx 3 db more power handling, so with enough power, more overall output than the JBL sub. The listening area is approx 1400 sq ft with 17' ceiling.
Rather than subject my still functioning original 700 to the bridging test, I will attempt to revive one of the remaining wrecks from the latest acquisition, only to beat it to death again with some bridging tests.
So if MJ151196's have a maximum Ic of 16 Amps and there are 5 in parallel could the rail fuses be increased beyond 8 amps? I vaguely understand that the 16 collector current would push the transistor beyond it's 'SOA' and continuous operation at the maximum potential bridged output would at the very least, overheat the power transformer, but with temp controlled fans, and attention to current sharring, emitter resistors, transistor matching..
