3. ed 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 Placement of the subwoofer will largely determine quality quantity and extension ofthe bass freq

7. uencies 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 Setup Suggestions continued Placing the subwoofer away from walls will provide the least reinforcement making the bass sound subjectively thinner than if the woofer were closer to a wall Good results can usually be obtained by placing a subwoofer along a wall 1 3 feet from a corner Experiment with placement of the subwoofer and the sub amplifier controls to achieve the proper bass balance It is important the signal being sent to the subwoofer be a non boosted or flat signal To be sure of this check the settings on your receiver or processor to determine any bass boost super bass or loudness is set to Off In most cases for home theater setting a receiver or processor will determine the crossover frequency through bass management settings In this configuration connect the receiver or processor to the LFE Line Level Input Your subwoofer can now reproduce the bass frequencies the way they were originally recorded Use the subwoofer level control and the individual bass management control within the receiver or processor to adjust the subwoofers volume if necessary Once set the volume controls should not need to be altered as the subwoofers volume will coincide with the master volume control of your receiver or proces
