Does any one here have a Sunfire subwoofer? I have three, 1 is out though, the other two were distorting so they could not be turned up that loud. Come to find out the screws for the drivers are all loose. Not just a quarter turn but on some 2 turns loose with one half way out. Was just curious to see if a Polkie has one if they could check the tightness of the screws. I can't imagine that they are meant to be only bottomed out when new. Thanks for any help.
