RBH Sound SI-663 - Manual (Page 2)

Introduction
Congratulations on your purchase of a RBH Sound SI-663 or SI-663/R In-wall LCR 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 the RBH
Sound SI-663 and SI-663/R In-wall LCR speakers. It is recommended you thoroughly
read through the material contained in this manual before 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.
For installations where a center channel is intentionally removed from a surround system
to allow for design requirements or otherwise cannot be used, the SI-663 or SI-663/R is
the perfect high-performance solution. A pair of these in-wall speakers can eliminate the
need for a dedicated center channel when wired for dual channel operation. For situations
where a third SI-663 or SI-663/R 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.
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.
Front Main Speakers
As a starting point, place your left and right speakers at least 7-feet apart from each
other. The distance from the listening position to each speaker should be close to the
distance that separates the two main speakers. The SI-663 or SI-663/R has the unique
ability to perform double-duty as both a center-channel speaker and as a main front left
or right speaker for a surround sound system.
Center Channel Speaker
If two SI-663 or SI-663/Rs are in dual-channel mode, the lower tweeter and woofer on
each side will function as the center channel, this allows the top two woofers and tweeter
on each speaker to be the front left or right channel. For situations where a dedicated
center channel can be installed, three SI-663 or SI-663/Rs can be used for the front left,
center and right channels for an outstanding in-wall home theater system. See the wiring
diagrams if you have questions.
Surround Speakers
The surrounds may be placed either above, behind or to the sides of the listening
position. The listening position should be centered between the surround speakers. For
best performance you may want to experiment with angling the surround speakers either
towards or away from the listening position.
