BI-WIRING
The bi-wire connection
method requires one amplifier
and two sets of speaker wires.
By removing the shorting
bars, connections may be
made to the individual network
sections using four conductors,
one for each of the four
terminals.

For single-wire connection,
leave the shorting bars in
place and connect only a
single set of speaker wires
(two conductors) to the two
upper terminals.

These models feature four
rubber feet that enable them
to be placed on a smooth-
surfaced floor, such as tile or
hardwood. Four metal spikes
are supplied for use when the
speaker is to be placed on a
carpeted surface, to decouple
the speaker from the floor and
prevent unwanted damping.
To insert the spikes, gently lay
the speaker on its side (not its

To insert the spikes, gently lay

four spikes are screwed in
completely for stability.

NEVER drag the speaker to
move it, as this will damage
the spikes, the feet and/or the
wood cabinet itself. Always
lift the speaker and carry it to
its new location.
