either the subwoofer or satellite binding posts. NOTE: This only applies to loudspeak-
ers 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 sub-
woofer.
Active Biamping
This option requires the utilization of an electronic (powered) external crossover. Ac-
tive 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 ac-
tive crossover is inserted between the preamplifier outputs and the inputs of two ste-
reo 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 con-
trols 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).
