I play bass. I've had a huge amount of it pump through my room. Trust me, I've had this thing looud, and my amps loud enough that people down the road were like "Holy ****!" and I still haven't had a problem with my machines. What kind fo components are fragile against sound waves? Well, I meen against bass. Anything can be shattered usually, but Bass is usually the last thing you think about when you think of a glass getting shattered. High pitched noises damage a lot of things, but bass, I've never seen it happen.
