Connection; Placement For Best Treble Dispersion; What Kind Of Wire To Use - JBL L1 Owner's Manual

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).
CONNECTION.
You will need...
3 Speaker wire i
3 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.
