of the
room.
Bi-wiring
The L7's
outer
connection
Panel
and
internal
dividing
network
are
designed
so that
separate
sets
of
speaker
cable
c¿n be
attached
to
the
woofer
(LF)
and
midrangd
treble
(HF) portions
of
the
dividing

This
confìguration
is
alledbi-wirîng.
Bi-wiring
can
provide several
sonic
advantages
and
considerably
more
flexibility
in
power amplifier
selection.
Reduction
of
intermodulation
The majority
of current
flowing
between
an amplifierand
speaker
is
devoted
to
the
reproduction
of
bass.
fn frLæ"60%
or more
of
an
amp's
power
is destined
for the
woofers.
When current
flows
through
a wire,
it
produces
a
magnetic
fìeld
(EMF) which
expands
and
collapses
at
a rate
