MOUNTING THE
SUBWOOFER
The 1000s and 1200s subwoofers can be
mounted from the outside of the
enclosure or from the inside of the
enclosure. Which- ever way you mount the
subwoofer, use the included foam
mounting gasket to ensure a leak-free
seal between the subwoofer frame and
the enclosure.

S
ETTING THE
I
MPEDANCE
The 1000s and 1200s subwoofers both
feature the Selectable Smart Impedance
™
(SSI) switch. This exclusive feature lets
you set the subwoofer’s impedance to
either 2 ohms or 4 ohms with the flip of a
switch (see illustrations to the right). This
allows you to extract the most from your
subwoofer amplifier in any situation.
The SSI 2-ohm setting increases the
subwoofer’s output over the 4-ohm
setting by up to 3dB, depending on the
amplifier. Performance is identical in all
4-Ohm Setting
other respects. If the connected amplifier
is rated for 2-ohm operation and its 2-ohm
power ratings are within the subwoofer’s
power-handling specifications, setting
the SSI switch in the 2-ohm position will
achieve maximum output.
IMPORTANT: Make sure the
subwoofer amplifier is turned OFF before
setting the SSI switch. Do not change the
switch position while the subwoofer
amplifier is operating. Doing so could
damage the amplifier.

ONNECTING THE
A
MPLIFIER
The Reference 1000s and 1200s subwoofer
connectors are compatible with quick-
disconnect (not supplied) or soldered
connections. The recommended wire gauge
is between 14AWG and 8AWG, depending
on the length of the wire run between the
amplifier and woofer. Heavier gauge wire
is preferred for runs over 6' (2m).
The wider terminal is the positive and the
narrower is negative (also indicated on
the terminal cover).
NOTE: If using untinned bare wire, be
sure that no stray “+” and “–” strands
touch each other. Touching strands can
cause a short circuit, which can damage
your amplifier.
