[Bi-Wired Connection]

This speaker system is capable of bi-wired connections. To 
connect the speaker to the output terminals of the amplifier 
(or receiver), two pairs of cables for each of mid-woofer/
woofer and tweeter used instead of standard connections.

This type of connection decreases the modulation 
distortion caused by electric resistance of the cables and 
driving current of the speakers. Consequently, purer sound 
quality can be expected.

To utilize bi-wired connections, remove the short bars 
from the terminals first, and then connect the mid-woofer/
woofer and tweeter to the amplifier separately using two 
pairs of cables.

.

Place the speakers on a sturdy, vibration-free surface, on a 
well-built stand.

Using as 2ch stereo speakers

Better stereo images will be obtained when the speakers 
are slightly angled in towards the listeners.

Using as main speakers in a multi channel 
system

Position the speakers on both sides of the TV. The 
positioning of speakers is important, because it controls the 
whole sound quality of a multi channel system. Set up the 
speakers on the basis of your listening position by 
following the owner’s manual supplied with your 
amplifier.

Note

This speaker features a magnetically shielded design, but there is 
still a chance that placing it too close to a TV set might impair pic-
ture color. Should this happen, move the speaker away from the 
TV set.
