Selling one of the best SQ subs ever produced according to others. These “old school” subs feature carbon fiber/Nomex honeycomb flat piston diaphragms driven by massive magnets on a die-cast aluminum frame. These subs were built like Sherman tanks, assembled in Phoenix with top quality parts from US speaker component factories. The PRO Flat Piston Subwoofer went on to win two SPL world championships in the well-known TeamGates “Beast” Bronco. This 15" model features an absolutely massive motor structure with a 5” diameter voice coil for handling serious amounts of power. This monster weighs in at 42.5 lbs!
It is in MINT condition. Asking 250 plus shipping. Serious buyers only! I also have two 10" Flat pistons if anyone is interested.
