RBH Sound SI-744 - Manual (Page 3)

Introduction
Congratulations on your purchase of the RBH Sound SI-744 In-wall Surround speaker! Your
speaker is the result of many years of research and development dedicated to producing
high quality products for home audio and audio/video systems.
This manual contains features, setup recommendations and specifications for RBH Sound
SI-744 In-wall Surround speaker. It is recommended you thoroughly read through the
material contained in this manual before installing or connecting your speaker. This
will ensure you have a good understanding of how to setup your speaker for optimum
performance and allow for years of listening enjoyment.
The SI-744 employs four proprietary 4-inch high performance metal cone woofers with
neodymium magnets 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.
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.
In order to obtain the best possible sound from your speaker system, it is important to
determine where the speakers will sound best in your listening room. Room reflections
from the floor, ceiling and side walls influence the balance, imaging and overall sonic
quality at the listening position. Experiment with speaker placement to determine which
location offers the best overall sound.

Speaker Placement
Break In Period
Allow several hours of listening time to adequately break-in the speakers. As the speakers
break-in, the driver suspension will loosen. The result of break-in will be an increase in
low frequency response, improved definition, and increased clarity and detail.
