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.
