The XTZ Cinema Series 3X12 subwoofer is one of the most powerful subwoofers we’ve ever tested. As soon as I had a chance to really get into the nuts and bolts of the 3X12, I could tell this was a serious product from a highly capable speaker company. It proved to be unflappable no matter what source material I threw at it or torture test I had it endure. Earning our Extreme Bassaholics rating was no problem thanks to the 3 x 12” high excursion drivers each with its own 500 watt Class D amplifier. This is a serious bass system at a very down to earth price.\n\nBest of all XTZ offers you a 60 day risk free trial with free shipping both ways. But, we are confident you won’t take them up on the return offer.\n\n\n\nRead: XTZ Cinema Series 3X12 Subwoofer Review\n\nAttached is our latest subwoofer measurement spreadsheet with all specs, CEA-2010 and Sweep data.\n\nWe think the 3X12 is one of the best values in high performance subwoofers.
