What destroys tweeters is almost invariably amplifier clipping. The tops of the waveforms are clipped off by a lack of voltage in the power supply, and the result is a squarewave or(almost)DC arriving at the tweeter that fries it. That happens when you're trying to get more power out of the amp than it can deliver. What you've probably done is exceed the linear range of the woofers(driven the voicecoil out of the magnet structure or bottomed it out in the magnet structure). If they still sound good at lower volumes, don't sweat it! I've done the same thing to my subwoofers with some sloppily recorded source material from time to time. If you want higher SPLs: Get more efficient speakers and/or some that can take the output of your 100wpc amps.
crackling noise at high volume
and its not my Rice Crispies ... when I turn it up to 1pm on my Bryston B60, feeding my Totem Arros, it breaks up. This is pretty much the highest volume/decibel level I could possibly push this system to. WHen its medium loud, no problems.
Any ideas who is at fault here?
