The subwoofer offers three types of connections. The ideal connection is made using a
single coaxial RCA cable from the amplifier's dedicated subwoofer output to the LFE input
on the subwoofer. The next best connection type is from an amplifier's stereo preamplifier
outputs to the two line level RCA jacks. The last connection choice is from the amplifier's
stereo speaker level outputs to the stereo High Level Input on the subwoofer. The 5-way
binding posts can accept bare speaker wire (up to 10 AWG), spade plugs, banana plugs, or
pin plugs.
There are several different ways to connect the subwoofer. The method you choose is
primarily determined by the presence of a dedicated subwoofer output on your
amplifier/receiver. The connection methods are presented in order of preference.
Connecting to a Dedicated Subwoofer Output
A dedicated subwoofer output is usually one or two RCA jacks marked "Subwoofer", "Sub
Pre Out", or something similar on the back of the amplifier/receiver. Refer to the
manufacturer's documentation for reference. Subwoofer outputs are monophonic, so if
you have two subwoofer outputs they are intended to drive two separate subwoofers.
To make this connection you will need a cable with a single RCA plug on each end.
1.
Insert the RCA plug at the one end of the cable into the LFE Input jack on the back
of the subwoofer.
2.
Insert the RCA plug at the other end of the cable into the subwoofer output jack on
the back of the amplifier/receiver.
Connecting to a Stereo Preamplifier Output
If your amplifier/receiver lacks a dedicated line level subwoofer output, the next best
option for connecting the subwoofer is to use line level preamplifier outputs. These
outputs should not be confused with line level outputs intended to connect components,
such as tape decks or DVD recorders, to the amp. Preamplifier outputs will usually be
marked as "Pre-amp Out" or something similar. Refer to your amp's owner's manual to
determine which, if any, outputs are the pre-amp outputs.
