I have owned SoundLabs since the 80's. Although panels made from the 80's until late 90's were fragile and could be damaged by excessive power or humidity corroding the points where the connections were made to the Mylar, the two cases of problems with panels I know about during the last ten years were due to mishandling during shipping or moving the speakers.
Since I own PX panels I became more confident, and I have played them a few times at much louder levels than before, fortunately without any problem and sounding great.
