2. For placement, start at 1/4 or 1/2 the distance in from the side wall in the same
plane as the front speakers. Then fine tune the placement until the bass response
is smooth at all listening positions. The Sub does not need room support for
impressive bass output.
3. When two subwoofers are used, the best sound usually results from placing
them in the room as recommended in the illsutration above(Figure 1).Because
most rooms have resonant modes (frequencies at which the room shape
emphasizes sound), such placement smooths bass response.
NOTE: If you experience buzzing or rattling during strong bass passages, it
may be necessary to relocate or remove items in the listening room which
become excited by the high energy levels reproduced by The Sub.
INSTALLATION
These sizes of quality speaker wire are recommended for The Sub
if the speaker level inputs are employed:
• 14 gauge up to 30'
• 12 gauge from 30' to 75'
• 10 gauge longer than 75'
When using The Sub speaker level outputs to drive main
speakers, consider the sum of both wire lengths (amplifier to
The Sub and The Subto speakers) when determining wire size.
When The Sub active crossover is used to divide the
preamplifier signal between the subwoofer and main speakers,
interconnect cables of sufficient length are needed to reach
from the preamp/processor to The Sub , and from The Subto
the amplifier driving the main speakers.Most preamplifiers are
capable of driving signals—
without loss of fidelity—
through quality interconnect
cables up to 20' long.
Maximize the fidelity of your
system with line level connec-
tions using premium cables
such as Sonance Bronze or
Silver MediaLinQ
®
oxygen-free
high-grade interconnects.
MediaLinQ interconnects are
available from your Sonance
dealer in lengths up to 20'.
To rea l i z e the full potential of
The Sub with speaker level
connections, use quality
speaker wire such as oxygen-
free Sonance Gold, Silver, or
Bronze MediaLinQ. An SPL (sound pressure level) meter is
available from most Radio Shack
®
stores. This is required to
calibrate an installation with a processor that includes an
internal 75db pink noise test signal generator.
The Suboffers many options for connection to other components
in your system. The methods discussed are listed in descending
order of preference, with the most ideal method first. Note that
more than one method may be valid for your equipment
configuration, and placement of your The Sub and main
speakers may dictate which you choose.
SUBWOOFER SETTINGS
Vol u me , ph a se, crossover bypass, and crossover frequency
controls on the front of The Sub maximize placement
flexibility(Figure 2).
Some experimentation may be necessary to achieve the best
possible integration of The Sub with the other speakers in the
system. If your source components include a processor with
provision for a subwoofer, refer to that component’s manual
for any special instructions for calibrating subwoofer
performance. Start the calibration process with the following
settings on The Sub:
