in your room (four times better) and of course offer double the power. In addition, some state-of-the-art home theater installations have begun to use a separate subwoofer hooked up to the rear (surround) channels and we recommend this for the absolute ultimate in performance. Dual Subwoofer Connections When hooking up a stereo pair of subwoofers, wiring is quite similar to traditional high level connections. Here, instead of running both speaker cables from your receiver or amplifier to the left and right high level terminals on the subwoofer, you will run the left channel to the left channel subwoofer and the right channel to the right channel subwoofer. Again, take care to make red to red ("+") and black to black ("-") terminal connections. Don't worry that on your left subwoofer the right channel terminals will be empty and that on the right channel subwoofer the left channel terminals will be empty-both channels are combined at the subwoofer's input stage. There is a possibility that with this type of wiring you may need to increase your gain a little bit for proper balance. A dual subwoofer system using low level connections is equally simple, just put a Y connector on your LFE output and run one cable to each subwoofer. Critical Bass Management Settings Your receiver or decoder has a bass management system which ABSOLUTELY must be set for you to get proper performance from your system. This is not something that is subtle in its importance. It is absolutely critical. In general if you are setting up a ProCinema System using our ProSubs, ProMonitors and ProCenters, follow these simple instructions: • If you are hooking up the sub with the low level LFE connection, set your receiver/decoder bass management to "Sub - Yes" and set left main, right main, center, left rear and right rear to "Small." • If you have a choice of crossover frequency, choose the highest one available. • If you use a speaker level connection where you run the speaker wire from the receiver to the sub adn then from the sub to the left and right mains, set "Sub - No," left main and right main to "Large," and center, left and right rear to "Small." • Also make sure you properly set the channel balance as outlined in your receiver/decoder manual. There is also more detailed information in your ProMonitor manual. 7

Dual Subwoofer Connections
When hooking up a stereo pair of subwoofers, wiring is quite similar to
traditional high level connections. Here, instead of running both speaker
cables from your receiver or amplifier to the left and right high level terminals
on the subwoofer, you will run the left channel to the left channel subwoofer
and the right channel to the right channel subwoofer. Again, take care to make
red to red (“+”) and black to black (“-”) terminal connections.
Don’t worry that on your left subwoofer the right channel terminals
will be empty and that on the right channel subwoofer the left channel
terminals will be empty—both channels are combined at the subwoofer’s
input stage. There is a possibility that with this type of wiring
you may

Your receiver or decoder has a bass management system which
ABSOLUTELY must be set for you to get proper performance from
your system. This is not something that is subtle in its importance.
It is absolutely critical. In general if you are setting up a ProCinema
System using our ProSubs, ProMonitors and ProCenters, follow these
simple instructions:
• If you are hooking up the sub with the low level LFE connection,
set your receiver/decoder bass management to “Sub – Yes” and set
left main, right main, center, left rear and right rear to “Small.”
• If you have a choice of crossover frequency, choose the highest
one available.
• If you use a speaker level connection where you run the speaker
wire from the receiver to the sub adn then from the sub to the left
and right mains, set “Sub – No,” left main and right main to
“Large,” and center, left and right rear to “Small.”
• Also make sure you properly set the channel balance as outlined
in your receiver/decoder manual. There is also more detailed
information in your ProMonitor manual.
