hi all! thanx for all the nice greets. like I said my k22 is now making a popping sound, I removed it from the motor board and tried it just to make sure it wasn't some sort of cabinet rattle. but sadly it is the woofer. it is from a set of 1980s hereseys ser#'s 124w559 and 124w560. I'll never part with them I just was wondering can they be repaired? Thanx
