B1 Subwoofer
Owner’s Manual
NOTE: Setting the level of the subwoofer in relation to the left
and right front speakers is of critical importance because it is
essential that the subwoofer integrate smoothly with the entire
system. Setting the level too high results in an overpowering bass
response. Setting the level too low negates the benefits of the B1
subwoofer.
MAKING CONNECTIONS
CAUTION: Never make or break connections unless all
system components are powered off.
Figure 8: Rear-panel input connectors
This section provides typical examples of cable connections with
different system configurations and devices. Review the owner’s
manuals for associated audio components to determine their connection
requirements.
The B1 subwoofer input connectors are located on the rear panel. Two
gold-plated RCA connector options are available – Sub In Low-Pass
Disabled (Normal) and L/R Low-Pass Enabled – as shown in Figure 8.
In most cases, you’ll use the Sub In connector, as it’s designed for
multichannel use. This input bypasses the low-pass filter, and is the
appropriate input for most installations. This connector should be used
when there is a dedicated subwoofer output available on the audio
processor or receiver.
Some processors incorrectly label the subwoofer output as LFE; others
offer both an LFE and a Subwoofer output. If there is no labeled
subwoofer output, use the LFE output. If the output has labeled
connections for both LFE and Subwoofer, use the Subwoofer output.
The L (Left) and R (Right) connectors on the rear panel of the B1 are for
use with 2-channel applications, where there is no dedicated subwoofer
output available. These inputs are automatically crossed-over by the
adjustable Low-Pass Crossover control on the rear panel. Having
the low-pass filter enabled helps offset the fact that most 2-channel
systems do not perform any high-pass filtering on the main speakers,
minimizing the advantages of using a subwoofer. These connectors
should be used in 2-channel applications where the receiver or
preamplifier lacks a dedicated subwoofer or LFE output.
NOTE: The Concerta B1 subwoofer has a third connection option
– wireless connection is also available when coupled with the
optional TX1 transmitter. Refer to the “Wireless Connection”
section found later in this manual for additional details regarding
this option.

Figure 9: Typical connection
This configuration is for use with multichannel processors or receivers
that have a single dedicated Subwoofer or LFE output connector.
Connect an RCA patch cable from the Subwoofer or LFE output on the
processor/receiver to the Sub In connector on the B1 rear panel, as
shown in Figure 9.
