I purchased the take 5.2 speaker set a month ago. I noticed that the center channel clips really bad at a deep vocal or snare drum section with the amp only a quarter turned up (-40db). I think im going to return it. Now the sub is vibrating weird at quieter certain frequencies. I thought it was just vibrating a lamp or something and then I put my ear to the sub and it lightly distorts at even low volumes. My wife (who couldn't care less about this stuff)said something is definitely wrong with that. Did I just get a bad set or what? I dont want back to the store and have them say "that's the limitations of the speaker".
