Connecting the speakers (continued)
Biwiring
These speakers support biwiring, allowing you to directly
connect the LF (low frequency) and HF (high frequency)
for each speaker. This connection method is intended to
achieve even better playback audio quality than normal
connections.
Use a pair of cables each for the LF (low frequency) and
HF (high frequency), and connect the + terminals to the
amplifier + terminal(s) and the − terminals to the amplifier
− terminal(s).
Remove both links
o Use speaker cables of the same length for both the
high-frequency and low-frequency connections.
o Remove the links connecting the two + terminals
together and the two − terminals together.

Checking the phase
If the polarities (+/−) of the left and right speakers do not
match, they will be out of phase and good stereo playback
sound will not be possible.
To check the phase, play a mono audio recording that has
strong bass frequencies through one speaker and then
both speakers. If the bass frequencies sound is weaker with
both speakers, they are probably out of phase.
If they are in phase, low-frequency sound should be rich
abundant and the stereo image should be placed in the
middle between the left and right speakers. If they are out
of phase, low frequencies will be missing and the stereo
image will be unclear. In this case, check the polarities
(+/−) of the connections between the speakers and the
amplifier.
By reversing the polarity for one speaker, the phase can
be corrected. Speaker cables are connected to the input
terminals on the backs of the speakers. The red terminal is
positive (+) and the black terminal is negative (−). Check
these carefully when making connections.
