The D-130s are very nice but some of the ones out of the guitar amps have been abused, however they are easily reconed. Wanna sell? For my home theater setup I have four JBL L-36 3-way speakers for the front and rear channels. I tried a JBL sub and it was not strong enough at the time (maybe they are now, but I don't like the pwered subs) so I have a Titanic 15" in a cabinet I built myself running back to a Crown Microtech 600 in mono.
For the Phase Linear face melting experience I have a pair of custom built cabinets similar to the Altec Valencia. They each have the JBL 3110 passive crossover, 15" JBL 2226 Woofers, and horns comprised of the JBL 2426 driver and the 2370A biradial horn. They have about 6 Ohms DC resistance and they can handle the modified Phase Linear 700B pushing 489 Watts per side. Enough that the amp finally overheated after a prolonged session of Humble Pie - Performance: Rockin' the Filmore. Did I mention it was pretty loud?
I used to play roadie for a band and I've been in the warehouse at West LA Music, where the visiting bands used to get their equipment for shows at the Forum, Long Beach Arena, Hollywood Bowl, etc. Lots of JBL in that place. Had a guy once tell me that you could take a pair of the JBL pro 15" woofers and connect them to the AC outlet in your house and they would hum at 60Hz for quite a while, never tried it though.
My bass cabinet has four of the JBL 12" 2206 mid-low frequency speakers and I have tried to blow them up with a 1000 Watt amp I built but I can't seem to smoke them with my horrible bass playing.
