I have read perhaps 70 reviews of the SVS 20-39 PVi and am starting to get worried. 90% say that are glass ratteling, lip curling awesome. My question is - does it HAVE to be? I watch a ton of movies and listen to a lot of music NOT loud. Will NOT loud movie and music will wake the "hood". Granted - I'm an old head banger that still plays some music . . . .to loud and I do like some movies . . . .loud. But are all these reviews expressing their opinions about vision blurring, teeth rattling, couch moving, guts turn to Jell-O, pants waffling, stuff falls off the shelves upstairs, call the fire department during NORMAL play? Or have I just made enemys with the next doors!
