Great quality products IMO. If you buy them new from a dealer you can somewhat get raped on cost...still nice products though.
As far as blowing them...I have like thier lowest model sub from a few years back (SW6123) that I keep around to thrash on. Rated at 250 wrms and I have sent it 600-700wrms numerous times, full tilt, no problem.
The coil is starting to get a blackish tinge to it, but I expected it. I did not expect it to last this long though. Its taken a beating...impressed me.
Thing can actually wang pretty nice with that much power, and still sound pretty good.
Their decks are awsome, all there is to that.
Id love to try their amps too, sometime.
