Speaker Placement (continued)
Subwoofer
Placement of the subwoofer will largely determine quality, quantity, and extension of the
bass frequencies within your listening room. Bass frequencies are reinforced by close room
boundaries. Placing the subwoofer in a corner will make the subwoofer sound louder and
boost the very lowest frequencies. Placing the subwoofer away from walls will provide
the least reinforcement, making the bass sound subjectively thinner than if the woofer
were close to a wall. Good results can usually be obtained by placing a subwoofer along a
wall 1-3 feet from a corner. Experiment with subwoofer placement and the sub-amplifier
controls to achieve the proper bass balance.
Break In Period
Allow several hours of listening time to adequately break-in the speakers. As the speakers
break-in, the driver suspension will loosen. The result of break-in will be an increase in
low frequency response, improved definition, and increased clarity and detail.

Pre-wiring the Speaker
1. Unpack the speaker cabinet from the shipping box.
2. Run the speaker wires from the terminal cup to an amplifier/receiver. Choose either the
default dual mode setup in wiring diagram 1 or the optional single mode setup shown
in wiring diagram 2.
Wiring Diagram 1. Dual mode option using speaker as both front channel and center channel

Pre-wiring the Speaker (continued)
Wiring Diagram 2. Single mode option using speaker as a L/C/R.

Installing the Speaker
1. Determine where each speaker cabinet will need
to be installed.
2. If the cabinet is installed in a vertical position,
the terminal cup will need to be on the top
(see figure 1).
3. Position and brace the speaker cabinet in-
between two studs by using a couple of
screws to hold the speaker in place
(see figure 2).
NOTE: The front of the cabinet should be flush

Figure 4
with the front of the studs.
4. Using the included wood screws, secure both
sides of the speaker as shown in figure 3.
Use a minimum of three screws per side to
secure the cabinet.
OPTIONAL: Use construction adhesive between
the speaker cabinet and studs to secure the
speaker in place.
6. Connect speaker wire to the terminal plate.
7. If the cardboard debris shield was removed
during the process of installing the speaker
wire, replace it (see figure 4).
8. With the speaker wire ran and the cabinet
secured between the studs the drywall can
now be installed.
IMPORTANT: To avoid vibrations between
the drywall and the speaker cabinet use
construction adhesive and adhere the drywall
to the speaker cabinet and studs for stability.
