i got these speakers a few days ago brand new.....wen i play music at 50% + volume with the sub only about 1/3 of the way...it sounds as if the speaker is touching the grill and sounds really distorted....these speakers should have no trouble at higher level of volumes so im not sure if i should return them or just leave... according to reviews these speakers are fine at really high levels of audio so i dunno wats going on here :S .....any theories on the problem ?
