Bi-Wiring & Bi-Amping
If you decide to bi-wire or bi-amp, you 
must remove
  
the jumpers between the terminal posts. Failure to do  
this could result in damage to your amplifier and loud- 
speakers. The binding post caps must be completely  
removed to remove the jumpers, which use ring terminals.  
There are color coded collars so you can identify which  
is (+) or (–) after you remove the caps.
Bi-Wiring (see Figure 1)
Bi-wiring can provide noticeable improvements in the overall 
transparency of your loudspeakers. Run separate speaker wires 
to the low and high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers, 
the lower set of binding posts are for the low frequency drivers): 
after removing the jumpers, connect one set of speaker wires  
to the upper terminals on each speaker and one set of wires  
to the lower terminals. Connect the other ends of both wire  
sets to the same amplifier outputs.
Bi-Amping (see Figure 2)
Bi-amping allows you to use separate amplifiers for the high and 
low frequency sections of your loudspeaker for greater dynamic 
range and lower distortion. We recommend that your separate 
amplifiers have identical gain to preserve the speaker’s voicing 
balance. After removing the jumpers, connect the speaker wires 
from the high frequency amplifier outputs to the upper set of  
terminal posts on each speaker. Follow the same procedure  
for connecting the low frequency amplifier outputs to the  
lower set of terminals. Remember to maintain correct wiring 
polarity (+ to +, – to –) in all connections.

These recommendations are for all connections
