THE SUBWOOFER
You are about to experience the accurate deep bass performance of our Cinema ™ subwoofers.
These subwoofers offer high output with low distortion, deep bass extension and superb definition.
To achieve optimal bass performance for music and home theater, please read through the guidelines
for subwoofer placement that follow.
INPUT FACILITIES
Low-Level Input
Allows connection from the Sub/LFE Output of an A/V receiver, processor or other suitable
low-level source.
CONTROL FACILITIES
Auto On/Standby
Subwoofer will turn on when it receives an input signal and the LED will turn Green. If no signal is sensed
for a period of time, the subwoofer will automatically switch to Standby and the LED will turn Red.
Subwoofer Level
Balances the subwoofer output level to your speaker system’s output.
Subwoofer Cut-Off Frequency
Controls the subwoofer’s upper-frequency cut-off to match the low-frequency characteristics of
your speakers.
Subwoofer Phase Switch
Changes the phase of the subwoofer by 180
o relative to your speakers.
SUBWOOFER PLACEMENT
We recommend positioning your subwoofer close to the wall, between the front speakers.
Corner placement, Fig. 7 (
❶) provides the most bass, but sometimes at the expense of accuracy. A
subwoofer placed near a wall ( ❷) usually provides a good balance of quantity and accuracy.
SPEAKER CONNECTION
Turn your amplifier OFF before connecting speakers.
This will avoid damage which could result from accidental
shorting of speaker cables.
Your speakers are equipped with binding posts that can be used with banana, pin or spade
connectors, as well as with bare wire. Using high-quality speaker cable (see your Dealer), connect
one speaker at a time to your amplifier. Connect the red (+) amplifier terminal to the red (+) speaker
terminal and the black (–) to the black (–) (Fig. 6). Tighten the posts firmly by hand, but don’t over-
tighten them.
Turn your amplifier on and listen to your speakers. If you notice a complete lack of mid-bass and a
dislocated image, one or more of your speakers may be connected out-of-phase (their polarity is
reversed). Re-check to ensure that each speaker’s cable is connected with correct polarity: red (+) to
red (+) and black (–) to black (–). Make sure wires are firmly fastened.

WALL MOUNTING
If you are not comfortable performing the following mounting procedures, have a professional perform
the installation (see your Dealer).
FLUSH TO WALL USING KEYHOLES
NOTE: When mounting Cinema ™ center speakers, if you run speaker cable down the face of the wall,
apply self-adhesive bumper pads (included) to rear corners of enclosure to accommodate the cable.
1. Using #10 screws (not included) screw into the stud. (If model has two key holes, measure
distance apart and use two screws). If you cannot locate a stud, use appropriate mounting
hardware that will hold screws securely (see your Dealer). Do not screw all the way in, head
should stand out approximately 3/8 inch (9.5 mm). With ADP
™ speakers, head should stand
out 1/8 inch (3 mm). With Cinema™ CC, head should stand out 5/16 inch (8 mm). If using
bumper pads add 1/8 inch (3 mm) to the amount head stands out.
2. Connect speaker cables as outlined in “Speaker Connection” section of this manual.
3. Align keyhole to screw head, and using an “in and down” motion mount speaker to wall.
ANGLE BRACKETS (included with “L/R” and “C” speakers for optional use ) (Figs. 5a, 5b)
Angle brackets may be used to tilt your “C” speaker up or down (Fig. 5c) to optimize clarity and
intelligibility, and to tilt your “L/R” speakers slightly inward for better imaging.
NOTE: Position bracket so that the speaker’s sound is directed toward the listening area.
1. Using appropriate screws and hardware (not included) mount bracket with supplied safety
strap to stud at desired location. If you cannot locate to a stud, use appropriate mounting
hardware that will hold the bracket securely to the wall (see your Dealer).
2. Screw two #12 screws (included) into the two 60-mm holes in the back of the speaker
enclosure—do not screw them all the way in, heads should stand out approximately 1/8 inch
(3 mm).
3. Connect speaker cables as outlined in “Speaker Connection” section of this manual.
4. Connect safety strap to speaker using #12 screw in the remaining hole.
5. Hang speaker from bracket keyholes using an “in and down” motion.
