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 TWO Powered Subwoofer delivers with performance you would otherwise only find in much more expensive brands. We never use particle board or faux vinyl coverings as found in so many of today's speakers. Instead, we build our hi-end components into solid MDF wood with furniture-grade finishes of real wood veneer or mid-gloss black lacquer. Each cabinet includes internal bracing and a front-firing port for easy room placement. Rather than employing a simple port tube, our Level TWO Powered Subwoofer includes a 1/12th wave-length internal transmission line. This allows all of our speaker to produce more bass than other speakers of similar size.

The SDA-200 is a digital subwoofer amplifier built around an ICEpower® module designed by Bang and Olufsen and customized for our subwoofers. ICEpower® is designed for the finest in home audio sound and operates at over 80% efficiency. This keeps the amp nice and cool even during the most bass-heavy tracks and movie effects.

A 2.5" diameter voice coil with multiple winding 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 10" long-throw, reinforced doped cone woofer extends down to 29 Hz at -3dB.
