either the subwoofer or satellite binding posts. 

NOTE: This only applies to 

loudspeakers that incorporate the

 

subwoofer and satellite section in a 

single enclosure. It does not

 

apply towards the separate powered 

subwoofer/satellite configuration.

 

You must always observe the polarity 

when connecting the speaker

 

wire to a powered subwoofer.

 

 

Active Biamping 

This option requires the utilization of an electronic (powered) external 
crossover. Active biamplification is the most appealing means of 
interfacing a subwoofer/satellite system due to the control possibilities 
offered, but can also be the most costly. An active crossover is inserted 
between the preamplifier outputs and the inputs of two stereo amplifiers. 
Vertical or horizontal biamping considerations are also applicable here. A 
well designed active crossover will offer the user independent high pass / 
low pass turnover frequencies for optimally blending the satellites with the 
subwoofer sections of the speaker system. Other features usually found 
are separate level controls for the high pass or low pass sections and a 
choice of inverted or non-inverted low frequency outputs (needed when 
strapping an amplifier to mono).
