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.
