Ouch M&K 5000 Subwoofer

My M&K 5000 Subwoofer has gone out of control. Just walking in the same room was risky. Blew it's speaker grills 1/2 across the room. Had to find ear plugs to unplug it.

I really miss it now! Anyone have any ideas on repairing them at a reasonable price?
Try Aldo Filippelli @ 855-657-6863 hope everything works out.
