Low-Level Connections
Most often used is the LFE connection. Most receivers, preamps and decoders
feature a mono (line level) LFE/subwoofer output intended to be used with sub-

decoder to the LFE input on the subwoofer and achieve full performance.
[See
Diagram 1] Usually, these outputs have their own low-pass filter built into the
circuit, and if this is the case, you would normally input them into the LFE input.
The LFE inputs on your SuperCube subwoofer are direct coupled inputs which are
not affected by the subwoofer's low-pass filter or low-pass crossover control. If the
sub or LFE output on your receiver or decoder does not have a low-pass crossover
or you wish to use the SuperCube subwoofer's low-pass crossover and control in
