RBH Sound just introduced a new addition to their award-winning Signature Series In-wall speaker lineup. RBH Sound has many proven monopole in-wall models within their Signature Series which can be used for surround channels, but the SI 744 is the company's first dedicated multi-pole in-wall surround channel for the series. The SI 744 employs four proprietary 4-inch high performance metal cone woofers and two 1-inch silk dome tweeters for excellent performance and crystal clear sonic accuracy. True to RBH Sound tradition, the SI 744 is timbre-matched to the rest of the Signature Series In-wall and freestanding speakers.

The SI 744's design places two of the woofers and one tweeter on a 45-degree angle towards the screen, while the other two woofers and tweeter point on a 45-degree angle towards the rear of the theater. This 90-degree angle opposing design, combined with the SI 744's dual- or single-channel wiring capability, presents a unique surround sound solution. When integrated into the rear sides of a home theater system and wired in dual channel mode, the SI 744's front-firing drivers can play side surround channel audio and the rear-firing drivers can play rear surround channel audio. This configuration provides all four surround channels in a 7.1-channel surround sound system from one pair of SI 744s. In other words, RBH Sound dealers now have the unique ability to offer their clients four channels of surround sound when their room's design prevents another set of rear speakers from being integrated into the surround system. When wired in single-channel mode, the SI 744 presents its listeners with a bi-polar dispersed sound field for increased surround coverage.

As with other RBH Sound Signature Series In-wall models, the SI 744 features its own tuned enclosure to provide an optimized environment for the speaker and prevent unwanted cabinet resonance. The enclosure also boasts an integrated metal drywall cut-out ring and is designed to be installed into a standard stud-framed wall prior to drywall during new construction or renovation. The SI 744's baffle fits snugly into the area left over after the drywall is finished and is flush to the wall when complete which, RBH Sound says, will be a welcomed change from the typical in-wall Di-/Bi-polar protrusion from the wall the competition offers. The SI 744 is finished with a .5-inch thick black or off-white fabric grille which can be dyed to match the room's décor or custom finished by RBH Sound's professional custom integrator dealers.

The SI 744 can handle up to 250 Watts, has a frequency response of 70Hz-20kHz, and weighs 40 lbs each. The SI 744 has an initial suggested retail price of $1,600 per pair, and is expected to begin shipping this November.
