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.

This subwoofer amplifier can be positioned either with your other equipment (recommended) or close to, and even hidden beneath, the subwoofer cabinet.  Using a subwoofer amplifier not permanently installed in the back of the subwoofer cabinet (as many "old-style" subwoofers do) offers several key benefits:

• Air leaks around the built-in amp and its inputs/outputs, which can cause a buzzing or whistling noise, is a non-issue
• Internal volume of the cabinet is not reduced by the installed amplifier allowing the cabinet to be as small as possible
• You have the recommended option of placing the amplifier with your other equipment.  This allows the amplifier to be connected to your LFE (subwoofer) output on your home theater receiver using only a short, inexpensive shielded cable; regular speaker cable is run from the amp to the connection point on the bottom of the subwoofer cabinet.  This allows you to place the subwoofer exactly where you want without the need for running a 110V electrical cord to a nearby electrical outlet.  If you can hide the speaker cable under carpet, etc., the subwoofer can literally look like it is floating in the room with no cables in view.
• You still have the option of placing the subwoofer amplifier behind or beneath the subwoofer cabinet for a more traditional installation using a long shielded cable from your home theater receiver.  All of our cabinet-style subwoofers include a recessed area in the bottom of the cabinet that allows the amplifier to be hidden beneath it.

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.
