speakers
can
reproduce surpr¡s-
ingly
hþh
quality
bass under any
condition
and o<ceptionally
low
bass when
positipned optimally.
Two
modifiable rootn factors af-
fect
L Series bass:
l) proximity
to
room corners and
2) disønce from
the rear wall.
How close
your
L Series
speaker
systems are
to the
back
wall
determines how they will
"couple"
to that
surface, resulting
in increased
bass at certa¡n
fre-
quencies. The optimal
distances
from a backwall
(as shown in Fþ-
ures
lA, lC,
lE
and
the L7
Supplement)
will
produce
well-
balancêd bass
in a normal-sized
room.
NOTE:
You can increase or
decrease this
distance by about
one
foot
witlrout
seriously affecting
low frequency
balance.
The closer
tlre
speakers
are
placed
tö
room corners, the more
mid-bass
(boomy bass) they will
produce. lf
your listening room is
extremely
naffowyou may not be
able
to
place your L
Series speak-
ers at
least three feet from side
walls
as shown
in Drawings lA" lC
and I E.
lf this is the case,
decrease
the disønce between
the two
speakers
to allow at
least
some
disønce from side
walls.
Placement for best treble
dispersion
High musical sounds create the
fine deails of a musical experience.
High-frequency sounds such as fe-
male
vocals,
violins, lead guitars,
upper
piano octaves
and cymbals
are more
directional
tjran bass and
midrange. In other words, these
treble
sounds are best heard
when
they can
pro¡ect directly in
an
unencumbered
path
from the
speaker to
your
ean
Thanks
to their
tianium
dome
high frequency transducers,
L
Series speakerc
are less
sensitive
to
placement for
best treble than
almost any other speaker model..
Howeveçyou will ênjoy
your
best'
musical o<perience when ttre
L Series'tweeters are at or near
"ear
level"
as shown in Drawings
lB, lD lF and L7 Supplement
(an-
other
reason why we recommend
placing L |
's
on speaker
stands).

Speaker wire

A tape measure
É'
3 One of
the following depending
on wire type and
thickness:
Wire strippers, diagonal
pliers,
a
knife
or a
pair
of scissors
What
kind of wirc to
use
For best results,we
recommend
the use
of specially desþed
heavy-
Bauge,
ultralow
resistance
speaker
wire.
Available from
yourJBL
dealen it
ís able to conduct
the
maximum
power and frequency
bandwidth
of
your
amplifier
or receiver.
Howeve[ any
insulated, multi-
stranded
copper wire
may be used,
provided it is of the
proper
gauge
(thickness).The
easiest
to obtain
is
ordinary
lamp cord
(also
called
"zipcord'),
available at hardware
and home
improvement
stores.
The
minimum size of wire
to
use depends on the
length ofthe
wire between
the amptifier and
your
L Series
Speakers.
