Subwoofer
Outputs
A subwoofer is a special bass
speaker specifically designed to
handle ultra-low bass. It is driven by
its own power amplifier and is usu-
ally crossed over at 200Hz or lower.
While only rarely found in home sys-
tems, subwoofers are a common and
very effective way to generate bone-
crushingly realistic bass in a car.
Note that there are three subwoofer
outputs on the Harman Kardon
CXO-1 instead of one. These allow
great flexibility in type of subwoofer
and amplifier employed.
The Subwoofer output lets you send
separate left and right low bass
channels to a stereo power amplifier.
At that point you can either connect
the amp’s output to left and right
subwoofers, or connect both amp
channels to a single subwoofer
speaker which has dual voice coils.
The Mono Subwoofer output is
designed for mono power ampli-
fiers. A stereo subwoofer is not abso-
lutely necessary since there is less
differing left and right information
below 100Hz.
The Inverted Mono Subwoofer output
lets you use a stereo power amplifier
as amono unit to drive a single sub-
woofer. This is called “bridging” or
“strapping” and combines both
channels of the stereo amp into a
single output. IMPORTANT: Some
stereo amplifiers are not designed
for bridging and can be damaged by
doing so. Consult the stereo power
amplifier’s manual to determine if
the unit can be bridged for mono
output before connecting the
CXO-1’s Inverted Mono Subwoofer
outputs. Also, some stereo power
amplifiers have built-in “bridged
mono’ capability. In this case,
the inverted mono output needn't
be used.
