I was playing the newly acquired series II 5 string when all of a sudden my speaker cabinet started smoking then the amp went overloaded and burned up. What I was wandering is if anyone else has burned holes in there speakers?
The signal path was Series II to DS-5R Bass side to BassPod XT Pro Bi-amped to Stewart world 2.1 Lows to Eden 212XLT mids to Eden 410xlt. The treble side to Eden WT-800 to Mesa/Boogie Powerhouse 210 cab.
I have ran this setup on the Series I and the Hyak with no problems. Now with the Series II 5-string I let the smoke out of a lot of gear.
One of the 10" speakers has a 1/4" hole melted in the front cone and a 1 1/4" hole burnt in the rear fabric coil. The other 10" speaker has two 1/2" holes burnt into the rear fabric coil.
After disassembling the Eden wt-800 amp it looks like two of the rectifiers on the left channel cracked and let the genie out. My guess would be a loss of resistance in the speaker caused the amplifier to over run itself.
Any clarification would be greatly appreciated.

My guess would be DC from the amp killed the speakers...

Wow! That's bad Dale. Beyond my expertise, but hopefully some of the electronics experts around here can help out.

While I'm certainly no electronic tech, I did see this SEVERAL times back in my music store days . . . basically, the amp fails, goes straight into DC, the speakers become heat sinks, and the paper cones light up. You get extra style points if the grill cloth follows suit while you're playing the encore, crowd goes crazy.
This happened to us in the store several times as a famous manufacturer was using a particular acid bath formula on their PC boards that evidently smelled just like the female of the species to a roach once the unit was warm. Roach would crawl in, scurry about the circuit board looking for love, inevitably put one leg on a hot lead and another on a ground and POOF, the output transistors would blow and the juice would go straight to the speakers and the aforementioned phenomenon would ensue. It actually became a factory update and a warranty claim they honored on the pre-change units.

I love the roach story. As Bob Weir said: "Is there anyting a man don't stand to lose, when he lets a woman hold him in her arms?" Ain't it always that way: Look for love? Get burned! LOL

I was playing in a small jazz club with a bunch of "old school" jazz guys you know the ones "bass players play quarter notes and walk that's it got it". Well I like playing with these guys because usually one time a night I get a bass solo and they turn there heads as I slap, pop, tap, harmonic or anything else that will come out of these fingers. About 1/2 way into the solo I was getting a growl and popping out of the cabinet. then poof nothing. So while the drummer was still playing I waved a the Sound Engineer grabbed the mic that was in front of my cabinet unplugged the mic and plugged the cable into the D.I. on the BassPod XT Pro switched to mono and finished the solo. Talk about your heart racing. A couple of the people in the crowd actually saw what happed but most were like " yeah I would have had to take a rest in the middle of that solo too" Some people had seen the smoke coming out of the cab and were congratulating me. I was depressed because I knew I still have 2 weeks left before my new Dr. Bass cabs get here.
That is about it.
