The SubTwo by NHT is the subwoofer your neighbors will never forget. Two potent 10" woofers, driven by 500 Watts of power, equals authoritative low frequency reproduction all the way to 21Hz. The SubTwo uses specially modified versions of our 2.9 subwoofer, in a rectangular enclosure that offers placement flexibility. The driving force is provided by a built-in amplifier employing patented Sunfire technology, a design that boasts effortless power and high efficiency. The SubTwo Controller is a full rack-width processor with continuously variable tuning functions such as low-pass, high-pass and phase, as well as innovative dual-mode operation circuitry that optimizes its performance for either music reproduction or video soundtracks. The SubTwo Controller also offers the ability to run stereo subwoofers by connecting a second SubTwo enclosure from its stereo outputs. A 20-foot extension cable (Model X-20) is available to accommodate longer runs between the subwoofer and Controller.
