Fi no longer makes these subwoofers but they are monsters . 3,500 watts rms (definitely under rated ) Great SPL or SQ subwoofer. Built for ported , 4th order or 6th order boxes . Not even broken in yet . Put a little power to it to make sure everything is working well . Had it in a 7 cubic foot box and it got down .
