Powered subwoofers are uniquely designed to reproduce only the lowest frequencies in both movies and music-only applications. A good powered subwoofer dramatically improves the impact and emotion of what you hear. But not all powered subwoofers deliver on this promise.

The HTD Level THREE Powered Subwoofer delivers with performance you would otherwise only find in much more expensive brands. Cabinets are cut using computer-controlled machines and made of quality 3/4" MDF with internal bracing to minimize unwanted cabinet resonance. Unlike many of our competitors, we never cover our cabinets in cheap imitation-wood grain vinyl. Instead, our cabinets are painted black with mid-gloss lacquer or expertly covered in gorgeous real wood veneer. Each cabinet is designed with a front-firing port for easy room placement. Rather than employing a simple port tube, our Level THREE Powered Subwoofer includes an internal transmission line producing noticeably more bass than other subwoofers of similar size.

A 3" diameter voice coil with multiple wnding layers works together with a powerful neodymium magnet to keep the moving cone fast and accurate. While most of today's subwoofers use a ferrite magnet, we use neodyimium. Neodymium is significantly more expensive than ferrite which is why most manufacturers only use neodymium with smaller drivers, such as tweeters. Neodymium is used because it is 7 times more powerful than ferrite. This allows us to place the strength of the magnet in closer proximity to the voice coil. The result is a very fast moving driver that is extremely accurate and never muddy or boomy. The 12" long-throw, reinforced doped cone woofer extends down to 22 Hz at -3dB.

The SDA-200 digital subwoofer amplifier (included) was also carefully designed with features that allow the amplifier to be connected either directly to the LFE (subwoofer) output on your home theater receiver OR "in-line" using the speaker cables already in place for existing speakers in a room. And with some pre-planning, it is possible to easily add this subwoofer into any zone of a whole-house audio system. Watch the video for whole-house audio connection options.
