Doug - Buzz still present. Even distorts on Bob Segers voice from across the room.
BobG - Maybe my room is not exactly bass friendly, but when I turn the bass all the way up and stand next to the speaker is the only time I feel anything. The passives emit practically nothing. My little Aiwa 60W/channel bookshelf could make my old KLH's shake the floor (it sounded like crap though), and this Denon can't come close. Oh well, that's what i got the sub for. I'm just disappointed that I heard such great things about these speakers being able to handle anything you throw at them and mine failed. Im not giving up on these things, they sound terrific. Good news though, I found an audio site on the web with a pair of KG-4's with damaged cabinets, but the components are in good condition, unless anyone thinks it would be better to get new woofers. Again, thanks everyone for your help, hopefully I'll come back with good news.
