2-Ohm Setting

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.

CONNECTING THE

SUBWOOFER

SETTING THE IMPEDANCE

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.

CONNECTING THE AMPLIFIER

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.
