SDX-W65 Single Speaker


The SDX-W65 is sold here as a single speaker for use as a center channel or in rooms where a pair of speakers is impractical.

The SDX-W65 is an upgraded replacement to our MP-W65 in-wall speaker (

).  All X-series speakers include our new proprietary aesthetic design which offers the slimmest possible mounting profile and two distinct grille options that let you choose, before or after installation, which style looks best in your ceiling or wall.

The SDX-W65 is designed around a 6.5" polypropylene woofer and aimable silk dome tweeter, both of which are hidden behind the grille for a professional, flush-mount appearance. The +/-3dB switch on the tweeter offers acoustical control to compensate for speaker positioning and room anomalies and to better match the sound of other speakers in your surround sound setup. The speaker grilles and frame can be painted to match your decor.

Sold here as a single speaker, the SDX-W65 is perfect for completing your surround sound system and for use in whole-house audio where only one speaker can be installed.

In home theater, it is often used in height and surround locations, and occasionally is necessary as a front center channel speaker when cables have been run for a ceiling installation (however, in most cases, we recommend that the center channel speaker be as close to the screen as possible and on the same plane).

When using a single SDX-W65 in a room for whole-house audio, you will have to choose between listening to the left channel of a stereo recording or the right channel, unless you have an amplifier that will "sum" these two channels before sending the signal to the speaker. Our whole-house multi-channel amplifiers (excluding model MCA-66) and our sub-zone amplifiers include this feature. If your amplifier does not include this feature and you can only fit one speaker into the room, it is possible to combine the left and right channel at the speaker BUT you must use a special speaker (not the SDX-W65) AND you must run 4-conductor cable (or two 2-conductor cables) to the speaker, i.e. run your cable as if two separate speakers are being installed at the same location.

It is ideal for use in small and mid-sized rooms, both for entry-level home theater and background music for whole-house audio. The 6.5" polypropylene woofer produces warm mid and low frequencies and the aimable silk dome tweeter blends with smooth and clear highs. Polypropylene is used in many of today's better in-wall and in-ceiling speakers because it is lightweight, rigid, and cost-effective to produce. A light cone means the speaker is fast which is important for accuracy and detail; the more rigid the cone membrane the less the cone warps during movement, again resulting in a more accurate performance. Silk dome tweeters accurately reproduce the high frequencies and offer a smoother tone than other, less expensive fabric tweeters.

Like all of the speakers in our SDX line, the SDX-W65 includes an aimable tweeter that is recessed behind the grille. This allows the highest, most directional frequencies to be aimed at the primary listening area while allowing the speaker to maintain its flush-mount appearance. Tone is controlled through a +/-3dB switch for the high frequencies. This feature (normally found only on more expensive speakers) allows you to customize the sound to your room and personal taste.

The speaker is easy to install and includes all mounting hardware, a template for cutting the hole, and an Owner's Manual with an installation guide and tips to ensure your speakers look and sound great for years to come. Both of the included grille options and the polymer frame can be painted to match your decor.

All HTD speakers include a 5-year warranty and 30-day no-risk guarantee.
