^ You are, of course, talking about penngray. While he usually has good intentions, he just LOVES to argue/debate. I think everyone at AVS knows this. Best to just let him be I say.
Anyway, for what it's worth I have played music at 100dB levels (according to the SPL meter) and there was no compression or distortion. I, of course, do not listen that loud, but I wanted to see what the ST's could do. Once I hit a flat 100dB, that's all I needed to know. My ears were telling me to stop, and they were right. Case in point, they hit 100dB, stayed their consistently and the thump of the kick drum hit me in the chest almost as hard as a subwoofer would. I was shocked for sure. So yeah, they can go loud without distortion. Why anyone would ever listen that loud is beyond me, though.
P.S. The ST's are great for home theater. When placed in a very large room, however, they may not fill it to everyone's content. This, of course, should be obvious to most people. There is only so much the small 5" drivers can do.
