Bi-Wiring & Bi-Amping (D11 and D9 only)
If you decide to bi-wire or bi-amp, you must remove the flat metal jumpers between terminal posts. Failure to do this
could result in damage to your amplifier and loudspeakers.

Bi-wiring, or using separate speaker wire connections for high and low
frequency sections.
Bi-wiring can provide noticeable improvements in the overall
transparency of your loudspeakers by running separate speaker wires
L
to further enhance its low and high frequencies. After removing the
jumpers, connect one set of speaker wires to the upper binding post
terminals on each speaker and one set of (usually heavier gauge) wires
_
+
to the lower binding post terminals. Connect the other ends of both wire
sets to the corresponding amplifier outputs.
Bi-amping, or using separate amplifiers for the low and high frequency
sections of your speakers.
AMPLIFIER
Bi-amping allows you to use separate amplifiers for the high and low
R L
_ _
frequency sections of your loudspeaker for greater dynamic range and
+ +
lower distortion. 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.
Ensure the sensitivity of each amplifier is the same to avoid poor sound
quality.
