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 Sub 80 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 plastic port tube, the Sub 80 Powered Subwoofer includes a front-firing elliptical port built right into the cabinet's structure.  This allows the subwoofer to produce more bass than other speakers of similar size, and without port noise.

The SDA-100 is a digital subwoofer amplifier that stays 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.
The SDA-100 includes both a line level input for connecting to a LFE or Subwoofer output on your stereo or home theater receiver, as well as high level inputs and outputs which make it ideal for connecting the subwoofer within a zone that only has a high level (amplified) signal being sent into it.  This is common for most zones in a whole-house multi-zone system.

Our proprietary 8" long-throw, reinforced doped cone woofer extends down to 32 Hz at -3dB.  The driver includes a 2" diameter voice coil with multiple winding layers that works in combination with a powerful magnet to keep the moving cone fast and accurate.  In short, you won't find a better combination of an 8" driver, furniture-grade cabinet, and digital amplifier anywhere near our price.
