i messed around tonight,first tightened drivers a bit,then listened.a little better but was more of a crackle instead of a popping type sound,maybe because i got just a bit more volume before i could hear it.took out each woofer one at a time checked the clips, are the leads causing the problem in th center channel inside the speaker frame?i got an old NAD integrated from someone a few days ago maybe thinking my right channel was going bad,but unless i have 2 bad right channels in a row.did notice it sounded like it was just coming from the top woofer.could be the woofer just failed?it would be nice just to send a woofer in instead of the whole speaker,i do have box but i bought these off audiogon.will probably just give them a ring this week.bummed out i want to watch ROTK with at least a little volume, the speakers would and should sound awesome
