Amp crossovers question

Discussion in 'Amps and Cabs [BG]' started by fleabee, Apr 28, 2009.

  1. Can running a cab without a crossover fuse cause damage to any amp or the drivers themselves?

    If the head or the cab has a fuse, and you defeat it (take it out of the circuit) and run it , it will be in danger. the fuse is there for your safety, go buy a hand full and it will be $3.50 well spent

    I think they are calling that light bulb that is flashing inside our cabinets a fuse, eh? :meh: BOB
  5. I think your right, leave it out and the horn won't honk, eh? That's about it :)
  6. Hmm its in the crossover inside the cab and looks like a mini light bulb{thought it was a fuse}.
  7. Well it actually is a small lightbulb, so called "soffitte", which is put in parallel to your crossover circuitry. Its use is to act like a ptc-resistor to prevent your cab from damage from too much load.

    uhh I am a little bummed to hear this. My cab which has these (lamps/fuses) whatever in them took a dump on me. I have blown fuses in my 115rb.

    question: Will a perfectly fine cabinet work without it's lamps?

    if yes i will my cabinet blew out as a result of me not keeping up with the condition of these lamps?
