RBH Sound PC-10 SUBWOOFER - Manual (Page 3)

Care and Cleaning
To maintain speaker appearance, we recommend an occasional application
of furniture grade polish to the wood surface of the cabinet. To clean dust from
the grille cloth, use a vacuum with a brush attachment.
Features
A powered subwoofer is a must-have component for any home theater or
audio system. The performance of your subwoofer can greatly affect the
overall performance of your system. Without the powered subwoofer, the
deep bass on your music CDs and special effects on DVDs may not be heard
and/or felt. Think of a subwoofer as a vital component that adds excitement to
your theater or music experience. The powered subwoofer has its own source
of amplification (as opposed to passive, non-amplified subwoofers which
require an additional power amplifier). Subwoofers can add considerable low-
frequency, deep bass performance to any home theater or audio system.
At the heart of the RBH PC-10 powered subwoofer is a compressed cellulose
composite cone driver. The driver material produces enhanced bass definition
and accuracy. A powerful magnet, enhanced suspension and heavy duty
voice coil give the driver elevated performance allowing high output capability
and accurate dynamic reproduction.
The PC-10 powered subwoofer incorporates a discrete class A/B analog
power supply amplifier ensuring low distortion, high current output and proven
reliability. Variable crossover, adjustable phase control and auto on/off are also
used for convenience and easy integration with other speakers. Connectivity is
made easy by allowing the subwoofer to be connected by either interconnect
(processor/line level) or speaker wire (high level).
Cabinets are constructed from medium density fiberboard because of its inert
properties. The thickness of the front baffles also prevents excess acoustic
radiation. Large oversized gold binding posts ensure a good electrical contact.
Sophisticated computer modeling and measurement techniques are used
extensively in the RBH subwoofer design process.
Setup Suggestions
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.
