Introduction
Congratulations on your purchase of RBH CT Series speakers! Your speakers are the
result of many years of research and development dedicated to producing high quality
products for home audio systems.
This manual contains features, setup recommendations and specifications for the RBH
CT Series speakers. We recommend you thoroughly read through the material
contained in this manual before connecting your speakers. This will ensure
you have a good understanding of how to setup your speakers for optimum
performance and allow for years of listening enjoyment.

Break-in Period
Allow 10-15 hours of listening time to adequately break-in the RBH CT Series loud-
speaker systems. As the speakers break-in, the driver suspension will loosen. The
result of break-in will be an increase in low frequency response, improved defini-
tion, and increased clarity and detail.
Care and Cleaning
To maintain speaker appearance, we recommend wiping them down with a clean
and damp, soft cloth. To clean dust from the grilles, use a vacuum with a brush
attachment.

Features
At the heart of the RBH CT Series speakers are proprietary aluminum cone woofers
and midrange drivers. Aluminum combines stiffness, low mass and self damping
properties in a manner which allows virtually uncolored presentation of program
material.
A powerful magnet, extended voice coil and bumped back plate give the bass/
midrange divers high excursion capability. This ensures accurate dynamic
reproduction. The drivers are shielded by a steel cup and additional magnet to
cancel any stray magnetic field that my cause interference with video equipment
such as tube televisions.
For high frequencies, a high quality silk dome tweeter is used. This tweeter is also
magnetically shielded, and uses liquid cooling to allow greater power handling.
Each CT Series speaker features an extensive crossover network. Steep acoustic slope
crossovers are used to integrate drivers. The use of steep crossover slopes allows
for higher power handling, minimizes driver interaction anomalies, and maximizes
the ability of each driver in their respective band of frequencies. Large 5-way binding
posts ensure a good, solid electrical connection to these crossover networks.
Cabinets are constructed from cast aluminum. The cabinets also have a narrow
profile to minimize cabinet diffraction. The speakers virtually disappear
leaving only a deep, wide sound stage with pinpoint imaging. Gold binding
posts ensure a good electrical contact. Sophisticated computer modeling and
measurement techniques are used extensively throughout the RBH CT Series
speakers design process

Attaching Speaker Wires
When using a banana jack to attach speaker wires to the binding post terminals,
insert the speaker wire into the banana jack. Next insert the banana jack into the
hole provided in the top of the terminal, and then continue to tighten the nut until
secure. Repeat for the other speaker wire(s) as necessary.
If not using a banana jack, simply loosen the binding nut to allow the hole in the
side of the terminal to become exposed. Strip ¼-inch of the insulation from the end
of the speaker wire and insert the exposed wire end into the now exposed hole in
the side of the terminal. Tighten the binding nut by turning the nut clockwise until
the speaker wire is secured. Repeat for the other speaker wire(s) as necessary.

Room Setup Suggestions
In order to obtain the best possible sound from your speaker system, it is impor-
tant 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. As a general guide, use
the room layout diagram and the following descriptions when setting up a home
theater system. Some speakers shown in the diagram on the next page may not be
applicable to your individual system.
Front Main Speakers
As a starting point, place your left and right front speakers at least 15 inches from
the wall and 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.
Angling the speakers inward towards the listening position may give a more spacious
and realistic sound stage. The MM-ꢁ speakers should be placed on stands which places
the tweeters close to ear height.
Center Channel Speaker
The C-ꢁ Center Channel Speaker should be placed between both left and right main
speakers. Often this positioning dictates placing the speaker either directly above or
below a television monitor. Since the MM-ꢁ and C-ꢁ speakers are video shielded, they
may be placed in close proximity to a television without cause for concern.
Surround Speakers
The Surround Speakers 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.
Subwoofer
Placement of the subwoofer will largely determine quality, quantity, and extension of
the bass frequencies within your listening room. Bass frequencies are reinforced by
close room boundaries. Placing the subwoofer in a corner will make the subwoofer
sound louder and boost the very lowest frequencies. Placing the subwoofer away from
walls will provide the least reinforcement, making the bass sound subjectively thin-
ner than if the woofer were close to a wall. Good results can usually be obtained by
placing a subwoofer along a wall 1-ꢀ feet from a corner. Experiment with subwoofer
placement and the sub-amplifier controls to achieve the proper bass balance.

Room Setup Suggestions
NOTE: There are several different surround formats available. Dolby Pro-Logic, Pro-Logic II, Dolby Digital and
DTS generally have a 5 speaker plus subwoofer requirement. Dolby Digital EX and DTS ES add a center rear
speaker. Please consult your audio/video professional to determine which system is best for you and how
many speakers you will require.
