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 al-
ways 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 cross-
over is inserted between the preamplifier outputs and the inputs of two stereo amplifi-
ers. Vertical or horizontal biamping considerations are also applicable here. A well de-
signed 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 fre-
quency outputs (needed when strapping an amplifier to mono).
