Bi-wiring Connections
Bi-wiring requires two cables for each speaker, one for high
frequencies and one for low frequencies. Using separate
cables for the high end and low end improves the sound.
1 Loosen the cap knobs on the left input terminals and
remove the two short bars.
In this state, the low-frequency speakers and the higher-
frequency speakers are completely independent. Store the
short bars in a safe place for later use. The lower terminals
are for the bass, and the upper terminals are for midrange
and treble sounds.
Attaching and removing the front grille
The front grille of this speaker system is removable. Follow
the instructions below to attach/remove the grilles.
Attaching the grille
1 Insert the supplied fastening screws into the four
holes provided on the front of the speaker.
Use your fingers (not a screwdriver) to secure the screws to
the front of the speaker.
2 Line up the holes on the grille with the protruding
ends of the screws on the front of the speaker and press
firmly.
3 Insert the supplied finishing screws into the four
holes on the front of the grille and tighten to secure.
Use your fingers to tighten the finishing screws.

2 Insert a speaker cable into each of the terminal post
holes, then tighten the knobs.
Caution: when bi-wiring
Note that in this setup, connecting the cables with the
polarity reversed may seriously degrade the tone; refer to the
section "Connecting the cables" again and confirm that the
cables are connected properly.
3 Connect the matched pairs to the same speaker
terminals on your amp (taking care not to get the
polarity reversed).
Make sure to use the same type of cable for the low-fre-
quency and the same type for the high-frequency connec-
tions.
When bi-amping
Bi-amping is an even more powerful way of connecting your
speakers. Just as with bi-wiring, the input terminal short bars
are removed, but here the low-frequency terminals are
connected to a separate, dedicated low-frequency amp, and
the high-frequency terminals are connected to a dedicated
high-frequency amp.
