JBL Grand Touring Series
subwoofers are available in two
different configurations: as dual
4-ohm voice coils or as dual 2-ohm
voice coils. Depending on the
amplifiers you are using, you may
use GTO subwoofers in singles or
multiples to maximize the power
available from your amplifiers. To
achieve the maximum amplifier
output possible, you should design
a speaker system that provides
the lowest impedance that your
amplifier will drive safely. When
designing a subwoofer system,
consider the following rules:

designing a subwoofer system,
consider the following rules:
1. Do not mix different subwoofers or
enclosure types in the same sys-
tem. Subwoofers being used in the
same enclosure or powered from
the same amplifier should be iden-
tical models. Mismatched woofers
and enclosures can result in poor
performance from your subwoofer
system.

2. You may connect the coils of a
dual-voice coil woofer in series,
but we recommend that you avoid
connecting separate woofers in
series.
