I recently purchased an Earthquake Sound MKIV-12 Supernova subwoofer. It replaces an old 12" JBL subwoofer. After watching several movies on Blu-ray (The Expendables 3, Guardians of the Galaxy and Django Unchained) I have to say that I love this subwoofer. The louder you turn it on, the better it sounds. My theater room is 12" x 12" and fills the room with deep, ringing bass. My setup is an Onkyo THX2 receiver and Mirage speakers. If you're looking for a subwoofer at this price point, look no further.
