Excellent Bargain!
I bought the Earthquake SLAPS-M12 passive radiator and installed it in the QBomb 12" enclosure. I had to cut a circular hole on the back of the cabinet to mount the radiator. I then installed a 12" Audio Pipe quad stack magnet sub - one of their newest models. This compact enclosure is in my Mustang convertible trunk and pounds really hard. Tight, solid bass and no port noise like you can encounter with a ported enclosure. A++
