SPEAKER PLACEMENT 

Proper placement of the 

speakers is an important step 

in obtaining the most realistic 

soundstage possible. These 

recommendations are for the 

optimum placement of the 

loudspeakers. Use these 

placement recommendations 

as a guide. Slight variations 

will not diminish your listening 

pleasure. 

All of the Northridge E Series 

loudspeakers referred to in 

this guide are video-shielded 

and can safely be placed 

near a television.

5 – 6 ft. 

(1.5m–1.8m) 

MODEL: EC35 

0 – 2 ft. 

(0–0.6m) 

The EC35 center channel 

loudspeaker is designed to 

complement all of the 

Northridge E Series loudspeakers. 

It is the ideal way 

to re-create the cinematic 

experience in your home.

Receiver’s Speaker Outputs 

Speakers and electronics terminals 

have corresponding (+) 

and (–) terminals. It is important 

to connect both speakers 

identically: (+) on the speaker 

to (+) on the amplifier and (–) 

on the speaker to (–) on the 

amplifier. Wiring “out of 

phase” results in thin sound, 

weak bass and poor imaging. 

To use the binding-post 

speaker terminals, unscrew 

the colored collar until the 

pass-through hole in the center 

post is visible. Insert the 

bare end of the wire through 

this hole; then screw the collar 

down until the connection 

is tight. 

The hole in the center of each 

collar is intended for use with 

banana-type connectors. To 

comply with European CE certification, 

these holes are 

blocked with plastic inserts at 

the point of manufacture. To 

use banana-type connectors 

requires the removal of the 

inserts. Do not remove these 

inserts if you are using the 

product in an area covered by 

the European CE certification. 

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.

Bi-Wire Connections 

MODELS: E30, EC35, E50 

The supplied self-adhesive 

rubber feet may be attached 

to the bottom corners of your 

speakers to protect your 

furniture. 

MODELS: E60, E80, E90, 

E100 

These models feature four 

rubber feet that enable them 

to be placed on a smoothsurfaced 

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 

front or back) on a soft, 

nonabrasive surface. Each 

spike screws into the threaded 

insert in the center of each 

rubber foot. Make sure all 

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. 

CAUTION: Floorstanding 

(tower) loudspeakers have a 

high center of gravity and may 

become unstable and tip over 

during earthquakes, or if 

rocked, tipped or improperly 

positioned. If this is a concern, 

these speakers should be 

anchored to the wall behind 

them, using the same procedures 

and hardware customary 

for anchoring bookcases 

and wall units. The customer 

is responsible for proper installation 

and proper selection of 

hardware.

TROUBLESHOOTING 

If there is no sound from 

any of the speakers: 

• Check that receiver/amplifier 

is on and that a source is 

playing. 

• Review proper operation of 

your receiver/amplifier. 

If there is no sound coming 

from one speaker: 

• Check the “Balance” 

control on your receiver/ 

amplifier. 

• Check all wires and connections 

between receiver/ 

amplifier and speakers. 

• Make sure no wires are 

touching other wires or 

terminals and creating a 

short circuit. 

• Make sure all wires are 

connected. Make sure none 

of the speaker wires are 

frayed, cut or punctured. 

• In Dolby* Digital or DTS ® 

modes, make sure that the 

receiver/processor is configured 

so that the speaker in 

question is enabled. 

• Turn off all electronics and 

switch the speaker in question 

with one of the other 

speakers that is working correctly. 

Turn everything back 

on, and determine whether 

the problem has followed the 

speakers, or has remained in 

the same channel. If the 

problem is in the same channel, 

the source of the problem 

is most likely with your 

receiver or amplifier, and you 

should consult the owner’s 

manual for that product for 

further information. If the 

problem has followed the 

speaker, consult your dealer 

for further assistance or, if 

that is not possible, visit 

www.jbl.com for further 

information. 

If the system plays at 

low volumes but shuts 

off as volume is 

increased: 



amplifier and speakers. 

• Make sure all wires are 

connected. Make sure none 

of the speaker wires are 

frayed, cut or punctured. 

• If more than one pair of 

main speakers is being used, 

check the minimum impedance 

requirements of your 

receiver/amplifier. 

If there is no (or low) 

bass output: 

• Make sure the polarities 

(+ and –) of the left and right 

“Speaker Inputs” are 

connected properly. 

• Consider adding a powered 

subwoofer to your system for 

use with digital “.1” surround 

formats. 

If there is no sound from 

the surround speakers: 



amplifier and speakers. Make 

sure all wires are connected. 

Make sure none of the 

speaker wires are frayed, 

cut or punctured. 

• Review proper operation of 

your receiver/amplifier and 

its surround sound features. 

• Make sure the movie or TV 

show you are watching is 

recorded in a surround sound 

mode. If it is not, check to 

see whether your receiver/ 

amplifier has other surround 

modes you may use. 

• In Dolby Digital or DTS 

modes, make sure your 

receiver/processor is configured 

so that the surround 

speakers are enabled. 

• Review the operation of your 

DVD player and the jacket of 

your DVD to make sure that 

the DVD features the desired 

Dolby Digital or DTS mode, 

and that you have properly 

selected that mode using both 

the DVD player’s menu and the 

DVD disc’s menu.
