 2004 PINNACLE LOUDSPEAKERS

We congratulate and thank you for choosing a PINNACLE® subwoofer. Our subwoofers exemplify the
best in modern audio technology, and are designed to produce tremendous amounts of deep bass. Please
read this manual completely to ensure the best possible performance from your Home Theater or sound
system.

SOLID BRASS ISOLATION CONES:
If your subwoofer comes with solid brass isolation cones be sure to install them into the bottom of your
subwoofer cabinet. They are an important part of the performance of the product and will improve the bass
definition. AC SubTM 100 owners: You must install the solid brass isolation cones for the bottom vent to
operate properly.
With the cabinet on its side, simply screw the cones into their receptacles on the bottom of the
cabinet. Then, with the cabinet upright, adjust the cones individually as needed to level the cabinet. When the
cones have been adjusted to the proper height, screw each nut up the threaded shaft flush with the bottom of
the cabinet to secure the height setting. If you intend to place your subwoofer on wooden or vinyl floors, we
suggest placing a penny under each cone to prevent any indentations.

PLACEMENT:

Recommended Subwoofer Placement:

a) within a few inches of the room corner closest to your left or right front speaker (maximum low bass

output);

b) within a few inches of the wall between your left and right front speakers (strong low bass output with

optimal blending to front speakers);

c) near any other room corner or wall.
Other locations will provide varying degrees of low bass impact and blending with your front speakers.
We recommend listening to your system, with the subwoofer in different room positions, to obtain a location
with an optimum response.

A Special Note for MicroburstTM owners: Due to the bipole configuration of your subwoofer be
sure to leave at least an inch between the rear woofer and your wall.

If you must place your subwoofer near baseboard heaters or forced hot air vents try to leave at least
3” of clearance for proper ventilation. Do not place your subwoofer outdoors, or in any wet or excessively
damp environment.
Note: Because of your subwoofer’s powerful magnet(s), be sure to place your subwoofer far enough
away from your TV (approximately 2-3 feet) to avoid color distortion and any other anomalies in the picture. If
you experience picture distortion, simply move the subwoofer away from the TV until the picture becomes
distortion free.

We also recommend keeping magnetic media such as audio/videotapes and computer disks at least 2
feet away from your subwoofer to prevent damaging them.

CONNECTIONS:
Complete all wire connections in your Home Theater/Sound system before plugging in your subwoofer
or turning on your receiver (amplifier).

Connecting Your Subwoofer:

To connect your subwoofer your receiver must have a dedicated phono (RCA) subwoofer output jack
(sometimes labeled LFE (Low Frequency Effects), Sub Out or Low Pass). Simply connect your subwoofer via
a standard phono cable (the same kind of audio cable used to connect your CD player, tape deck, etc.) from
your receiver’s phono subwoofer output to the input on the subwoofer. Then, wire your left and right front
speakers directly to your receiver’s speaker outputs. Please refer to the wiring diagram above for further
clarification. Do not connect the subwoofer to any receiver outputs intended for connection to tape decks or
Mini-Disc, DAT or VCRs recorders etc., as they will overdrive the subwoofer’s circuitry!
