RBH CT-5/CT-7 Owners Manual

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 specifications for the RBH CT-5/CT-7 loudspeaker system. We recommend you thoroughly read through the material contained in this manual before connecting your loudspeakers. This will ensure you have an understanding of how to setup your speakers for optimum performance.

Features

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 field 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 crossover 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 damage 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 profile 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.
