R8DT SUBWOOFER

INTRODUCTION

The Russound R8DT 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 R8DT keeps up its end of the deal in your home theater or audio system. With its built-in amplifier,

the R8DT fits into to any system, and is tuned for both stereo music audio and for a home theater surround setup. The R8DT 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 R8DT subwoofer ports are tuned to provide opti- mum bass reinforcement for systems designed primari- ly 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.
