R10DT SUBWOOFER

INTRODUCTION

The Russound R10DT active subwoofer delivers the chest-thumping deep bass sound you want for a super- sonic listening experience. Whether it’s the asteroids breaking apart in your favorite sci-fi movie or the in-your- face concert experience of a classic rock band perform- ance, the R10DT keeps up its end of the deal in your home theater or audio system. With its built-in amplifier, the R10DT fits into to any system, and is tuned for both stereo music audio and for a home theater surround setup. The R10DT filters out mid- and high-range frequen- cies by sending bass-only signals to its own amplifier via an active crossover network.

DUAL TUNED PORT DESIGN

The R10DT subwoofer ports are tuned to provide opti- mum bass reinforcement for systems designed primarily for home theater entertainment or for music listening.

With home theater systems, both ports are left open. This tuning provides an increase in low frequency output which is more ideal for movies where explosions and other action sounds need greater impact.

For music applications, one of the ports is blocked with the included plug. This tunes the enclosure for a flatter response with extended low frequency response. It will produce lower notes and do so more accurately.

CONNECTIONS

When you make connections make sure the power switches of all components are off, including the subwoofer.

Audio Cables

If you are connecting your subwoofer into a system made up of separate components (preamps and power amps), you will need audio cables long enough to reach the subwoofer from the preamplifier and the power amplifier.

Speaker Wire

Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We rec- ommend that you use 16-gauge wire for connecting the receiver to the front speakers.

Woofer

The front-firing 10-inch woofer has a 38mm diameter voice coil and vented pole piece for high power han- dling and more efficient operation.

Polarity

All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire in the pair is which.

Polarity is shown by a color strip on the insulation, by ridged molded into the insulation or be the colors of the wires, one copper and one silver.

Strip the insulation from speaker wire ends to reveal the bare conductors before connecting to receiver, sub- woofer or speaker terminals.

Note: Always connect the red + terminal on the receiv- er to the red (+) terminal on the subwoofer, and the black (–) terminal on the receiver to the black (–) terminal on the subwoofer. The same is true for connecting the receiver outputs to the front speakers red (+) to red (+) and black (–) to black (–).
