    I had an accident recently when I was watching a movie on DVD. My Kef Q15 loudspakers were blown up by my Yamaha DSP A2 amplifier. I could not check the amp's sound since I haven't got any properly working speakers to test the amp. So, does blowing up your speakers mean serious damage to your amp too? The amp was set to maximum volume (by accident) and the Kef's can handle a maximum power of 100 watt.

    Thanks,

    Dirk

    im pretty sure that the amps internal circuitary will prevent feedback through the amp and thus stop any damage to it?

    i recently had a similar accident with my yammy 520 amp, blew the crossovers on my speakers by setting the volume way too high, amp is fine though just the speakers that took most of the damage <img src="frown.gif" border="0">

    might need to check the manual to see if there are any protection fuses within the amp?

    There should be no damage to the amp but you will never know ... until you tried it out.

    Reason your speakers blow (considering the similar power rating) is that amps start clipping at some point. Means the amp is driven into distortion and puts out a square wave form (as opposed to a musical sinus wave form) - deadly for all speakers.<br />This also means it's easier to blow a speaker with an underrated amp rather than with an amp which is too powerfull - unless you drive it permanently too hard of course.
