SUBWOOFER
CROSSOVERS
There are
two
operational types
of
crossovers, passive and active.
Passive crossovers (coils
or
inductors) are placed on
the
speaker
leads between
the
amplifier and speaker.An active crossover
is
an
electronic filter
that
separates
the
audio signal fed
to
different
amplifiers. For optimum subwoofer performance,
we
recommend
using an active
80-1
OOHz
low-pass crossover
at
12dB/octave.
By
varying
the
wiring configuration of your speakers you can
create
an
impedance load
to
match your system.Altering
the
wiring configurations
gives a range of options for impedance loads. Series, Parallel,
or
Series-Parallel wiring configurations are different techniques for wiring
speakers
that
provide different loads. Series configuration
is
a string
method
where
speakers are wired end
to
end. Parallel configuration
uses
two
or
more
speakers wired across common terminals.
Series-Parallel configuration combines both techniques.
Choose
the
wiring diagram
that
corresponds
to
the
number of woofers and
the
impedance of your amplifier.
