Running 500W to a pair of SWS (250W each). No problems here. I have pushed them hard and never heard them struggle. You must have been really boosting the bass with your setup or doing something else to blow them. Too much power alone is rarely a cause for blowing a speaker. Its typically too little power or distortion causing overheating of the voicecoil.
