RBH Sound SI-663 In-Wall Speakers


Eliminates Need For Dedicated Center Channel

RBH Sound has introduced another new addition to their award-winning Signature Series In-wall speaker lineup. 2009 CEDIA Expo attendees were treated to the first public showing of the SI-663 outside the company’s demonstration sound room (SR-4) in the Georgia World Congress Center in Atlanta, Georgia this week.

Using three proprietary 6.5-inch metal cone woofers and two 1-inch silk dome tweeters, the SI-663 in-wall speaker is primarily designed to be used as the front left or right speakers in a home theater system. The new model will replace the series’ SI-6000 in-wall speaker which utilized an additional 6.5-inch driver, but had one less tweeter and less features. For example, the most noteworthy trait of the new SI-663’s is that a pair of them can eliminate the need for a dedicated center channel when wired for dual channel operation. Elaborating on the new model, Shane Rich, RBH Sound’s Technical Director explained, “The SI-663 is the ultimate hi-fidelity solution for situations where a dedicated center channel is intentionally removed from a surround system to allow for design requirements or otherwise cannot be used. Because of the SI-663’s design, a pair can provide discreet center channel audio from both the left and right front speaker without the use of a separate center channel speaker.” Rich also clarified that for situations where a third SI-663 can be used as a dedicated center channel, the trio can be wired in standard configuration, allowing each to discretely provide left, center or right channels for a seamless front sound stage.

The SI663 in-wall speaker features its own tuned enclosure to provide an optimized environment for the speaker while preventing unwanted cabinet resonance. The enclosure is designed to be installed into a standard stud-framed wall prior to drywall during new construction or renovation and includes an integrated metal drywall cut-out ring. The SI663’s baffle fits snugly into the area left over after the drywall is finished and is completely flush to the wall when complete. A .5-inch thick black or off-white fabric grille finishes off the look of the SI-663 and can be dyed to match the room’s decor or custom finished by RBH Sound’s professional custom integrator dealers.

Since the SI-663 incorporates RBH Sound’s proprietary metal cone drivers, it is timbre-matched to other RBH Sound Signature Series in-wall and freestanding models, allowing it to be combined with many other types of speakers for a voice-matched, customized home theater system. To eliminate light reflections off of the metal cone drivers from certain projector/screen combinations, RBH Sound also offers the SI-663 with black-anodized 6.5-inch metal cone woofers.

The SI663 can handle up to 300 Watts, has a frequency response of 55Hz-20kHz, and weighs 55 lbs. The SI663 has an initial suggested retail price of $1,450 each, and is expected to begin shipping this November.
