FINISHING THE INSTALLATION

CONNECTING THE LOUDSPEAKER

1. The terminals on your loudspeaker support Bi-amp or Bi-wire connections as well 

as standard connections.  Please choose your preferred method as described below 
in 

Figure 5 

on page 

8

2. At each loudspeaker,  route the wire to the input 

connectors, then separate the loudspeaker wire 
so that at least 2 inches of each conductor are 
free. Strip away 1/4 inch of insulation from each 
loudspeaker wire. Using correct polarity, connect 
the appropriate conductor to each five-way 
binding post.

 

   NOTE: OBSERVE CORRECT POLARITY: POSITIVE 

(+) GOES TO THE RED POST AND NEGATIVE (–) 
GOES TO THE BLACK POST. IF YOU ARE UNSURE OF 
WIRE POLARITY, SEE THE SECTION, CHECKING 
LOUDSPEAKER PHASE BELOW.

3. Connect the other end of the loudspeaker wires to the home theater receiver (or 

amplifier) in the same way.

4. Turn on the home theater receiver and calibrate all loudspeakers in the system 

according to the receiver manufacturer’s instructions.

BI-WIRE AND BI-AMP CHOICES

Bi-Wiring

In a Bi-Wired confi guration, separate cables are connected from the amplifi er or 
receiver output terminals to the speaker input terminals for the tweeter/midrange 
section and the woofers. Be sure to 

remove the straps

 linking the two sets of 

input terminals on the speaker. Your amplifi er and your loudspeakers may be 
damaged if you do not 

remove the straps

. This type of confi guration results in 

lower resistance between the amplifi er and speaker than a standard connection 
with the same gauge cable. Some listeners may prefer Bi-Wiring to a standard 
connection with lower gauge cable.

Bi-Amping

In a Bi-Amplifi ed system, the tweeter and midrange section are driven by a 
separate amplifi er than the woofer. Both amplifi ers are connected to the same 
preamplifi er output. Use the same model amplifi er for the tweeter and woofer 
inputs and be sure to 

remove the straps

 linking the two sets of input terminals 

on the speaker. Your amplifi ers and your loudspeakers may be damaged if you do 
not 

remove the straps

.
