The TH221 - When you must have high efficiency and 20Hz performance

The TH221's exceptionally low bass response is also perfect for the demands of today's HD commercial theatre or a one-of-a-kind high-end home theatre. As one of the most powerful and largest subwoofers on the market, the TH221 is bold, but accurately stated. There is no equivalent!

There is no equal for the Cine-Monster !
