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. 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 TWO Powered Subwoofer includes a 1/12th wave-length internal transmission line producing noticeably 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.  Our Level TWO and Level THREE 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 magnet to keep the moving cone fast and accurate.  The 10" long-throw, reinforced doped cone woofer extends down to 29 Hz at -3dB.
