Congratulations on your purchase of an RBH loudspeaker system! Your speakers are
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 specications for the RBH
CT-5/CT-7 loudspeaker system. We recommend you thoroughly read through the ma-
terial contained in this manual before connecting your loudspeakers. This will ensure
you have an understanding of how to setup your speakers for optimum performance.
At the heart of our CT-5/CT-7 systems are proprietary aluminum woofers and midrange
drivers. The special aluminum cone material combines stiffness, low mass and self
damping properties in a manner that allows virtually uncolored presentation of program
material.
A powerful magnet, extended voice coil and bumped back plate give the bass/midrange
drivers high excursion capability. This ensures accurate dynamic reproduction. The driver
is shielded by using a steel cup and additional magnet to cancel any stray magnetic eld
that may cause interference with video equipment such as tube televisions.
For high frequencies, a premium quality silk dome tweeter is used. This tweeter uses
Ferro Fluid
™
liquid cooling to allow greater power handling and is also magnetically
shielded.
Steep acoustic slope crossovers are used to integrate drivers. The use of steep cross-
over slopes allows high power handling, minimizes driver interaction anomalies, and
maximizes the clarity with which each driver is able to produce its respective frequency
band. A polyswitch, or current limiting device, is used in the crossover to prevent dam-
age to the tweeter if overdriven. This device is engineered to work 900% faster than
a fuse.
Cabinets are constructed from cast aluminum. The cabinets also have a narrow prole
to minimize cabinet defraction. The speakers literally 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 in the RBH loudspeaker design process.
