INTRODUCTION

Congratulations on choosing JBL

J Series Loudspeakers. Their highly

accurate, uncolored and balanced

sound character will greatly increase

your enjoyment of recorded music

and movies. JBL speakers are built

with careful attention to detail, using

only the highest quality materials.

They will provide many years of

excellent performance.

The J Series is the result of combin-

ing traditional JBL Signature Sound

performance values with elegant

contemporary appearance.

Maximum Cone Surface Area:

The J Series transducers have been

designed to maximize the cone

surface area, a technology that

allows for shorter excursion of the

driver without sacricing critical air

movement.

Maximum Efficiency: Larger air

movement coupled with shorter coil

movement allows the J transducers to

be very efficient. See specifications.

Maximum Transducer Control:

Reduces distortion by tightening

the control of driver excursion and

increasing driver linearity.

Smooth, Accurate, Extended

Response: The J Series transducers,

computer-optimized dividing net-

works, and bass reex cabinets com-

bine to give clear, crisp, accurate,

JBL Signature Sound.

Video Shielding: The J Center,

J900MV, and J1000MV models

incorporate magnetic shielding to

allow use on or next to Video

Monitors/TVs. The magnetic shielding

prevents stray magnetic elds from

creating any interference or distortion

of the video picture.

PLACEMENT

Bookshelf Models: For the best

stereo reproduction, the two loud-

speaker systems should be an equal

distance from your listening position

and separated so that the angle

between them, at the listening posi-

tion, is between 40 and 60 degrees

(see Fig. 1). For example, if your lis-

tening position is 8 to 12 feet (2.5m

to 4m) from each speaker, the two

systems should be about 8 feet

(2.5m) apart. Placing the loudspeak-

ers in corners or against a wall will

result in the strongest (not necessa-

rily the most accurate) bass. Except

for the J50, all J Series speakers

have their ports in the front so you

can place the rear of the speaker up

against a wall. In the case of the J50,

do not place the speaker closer than

3 inches (75mm) to the wall behind it

if possible.

For the best stereo imaging, we rec-

ommend that the systems be placed

so that the high frequency transduc-

ers are positioned approximately at

ear level of a seated listener. Every

room is dierent and there are dier-

ent tastes, so don’t hesitate to experi-

ment on your own.

Tower Models: The Tower models

cabinet height and driver placement

allow for speaker placement directly

on the oor. The video shielding of

the Tower models allows for the

option of placement very close to a

Video Monitor/TV. When the Tower

models are used as Left and Right

Channel speakers in a Dolby Pro-

Logic AV system, the shielding allows

the speakers to be placed up against

the sides of the Monitor/TV for a

compact AV system prole (see Fig.

2). If you desire better stereo imag-

ing, the speakers should be moved

further apart from each other, approx-

imately 2 to 3 feet (.75 to 1m) from

the sides of the Monitor/TV.

Center Channel Model: As the

center channel contains the dialog

and other central action sounds, the

speaker should be located very close

to the Monitor/TV and centered with

the Monitor/TV’s center line. Place

the J Center directly on top of or

directly below the Monitor/TV with the

front edge of the speaker grille ush

with the edge of the Monitor/TV. You

should have your Left and Right

speakers within a 2 ft or less height

range of your Center Channel for

proper sonic performance (see Fig. 3).

In Case Color Interference Occurs:

The speaker is shielded to work with

video applications, however some

color interference may be observed

on the TV screen depending on the

type of your TV set. If color interfer-

ence is observed, turn your TV o for

15 minutes and move the speaker

back about 1" from the front edge of

the TV. Turn on TV and recheck. If

this is not far enough, move back fur-

ther and experiment until the interfer-

ence disappears. You may have to

turn the TV o for a few minutes and

turn it on again to clear the screen.

CONNECTIONS

To connect the loudspeaker systems

to the receiver or amplier, use two-

conductor insulated wire. Your JBL

dealer can recommend suitable

cables, or you can buy wire at most

hardware or electronic stores. We

recommend #16 AWG wire as a mini-

mum size. If your speaker is more

than 30 feet (10m) from your receiver

or amplier, use larger diameter

lower gauge wire. Connections are

made at the terminals located on the

back of the J Series speakers.

Preparing the Hookup Wire

Carefully plan your wire lengths

before cutting any speaker wire.

Be sure to allow plenty of extra

wire to help hide paths in corners,

along baseboards, etc.

1. For Left and Right Speakers, rst

determine the wire length needed

between the most distant speaker

and the receiver or amplier.
