I listen to loud rock through my pair of RB-75. I've always blown speakers on previous brands I've owned. Is there some type of speaker protection I can install that will make it less likely that I will blow speakers? I'm using an NAD C 372 150w per channel amp. Thank you.

Thank you everyone for the quick and awesome responses! I'm going to get one RSW-12. Thank you!

I listen to loud rock on my stereo in a 12'x 12' (x10'high) room. I have a pair of RB-75. I don't watch TV through this system; it's just for listening to loud music. The RSW-15 is heavy and would be a hassle to carry upstairs, move later, etc. I would prefer two RSW-12 instead (or even just one RSW-12 if that's more then sufficent in a room my size). What, besides money, would I sacrifice by choosing two RSW-12 instead of one RSW-15? Thank you.
