Sad to hear - I am really liking both of mine. Have been using one for about a year now with nary a glitch which prompted me to get a second one for the other side of my standard system (replacing a Behringer DEQ2496). Very very curious about the signs and symptoms that would cause it to blow a speaker like that? Were you running at extremely high levels at the limits of the speaker when you got some unexpected boost or did it just kind of melt down sending all kinds of distortion to the driver? What effect caused it to blow (i.e. sudden engagement of Sub-synth, EQ, Mic Feedback at high listening levels etc)? It may be helpful to others that still use them to know what was going on to cause a major failure like that and prevent something similar from happening to them if it can be attributed to the unit...
In the military we were big on FMEA (Failure Modes and Effects Analysis) Process to aid us in identifying in-service equipment problems such as genuine design flaws, equipment malfunctions due to Quality Control in manufacturing etc. and of course procedural errors or RTFM/PEBCAK issues (aka Read The F'N Manual/Problem Exists between Chair and Keyboard = human error). In complex systems it is always easy to blame the new gear without first understanding holistically what was going on at the time. Sometimes (not all of course), it can be something totally unrelated that caused the failure in the first place and chance just happened to marry the two incidents (i.e the speaker was already on the precipice of failure after many years of faithful service). Case in point I once blew a second hand 15 inch sub driver I had used for several louder gigs before I started using a new Denon Mixer I aquired. For the longest time I thought it was the mixer that was the cause and was skitterish to use it at all. At the end of the day, it was a duff woofer which after replacing gave me several years of good use with that same mixer once I built up a comfort level to using it more. It just so happened that it chose that particular day I added the mixer to the equation to pack it in. I wasn't even pushing it to the limits. I now believe (but can't prove) that it may have been one or two gigs before that was the killer coups de gras that tipped the driver over the edge to failure and was never the fault of the mixer...
