INTRODUCTION

Congratulations on purchasing this JBL Synthesis Three home theater speaker. This
product represents the synthesis of everything that JBL has learned about the emo-
tional power of audio and video in over fifty years of preeminence in the field. It sets
new benchmarks in the use of “high technology” and provides you with the experience
of being in some of the world’s greatest movie-houses and concert halls, right at
home! JBL’s Synthesis Three speaker systems feature the following:

THX ® LICENSED HOME AUDIO SYSTEM:

When used with a Home THX controller

and amplifiers, your speaker system will deliver state-of-the-art THX home theater
experience to your home.  You will hear in your home, exactly what the director and
sound engineer heard in the recording studio.  The system will reproduce the audio
flawlessly and without distortion.

CINEMA/MUSIC SWITCHING:

The Synthesis Three main speakers (S3M) utilize dif-

ferent combinations of transducers that are specifically chosen for playing cinema or
music.  Via an electronic relay, the speaker mode can be switched, depending on
whether the surround processor is in the music or cinema mode.  The result is a
speaker that reproduces all sources incredibly!

HIGH POWER COMPRESSION HORN:

Horns are commonplace in movie theaters

across the world, because of their high power handling and well-defined high frequen-
cy output.   The horns employed in Synthesis Three have very low distortion, and a
well controlled directivity, to put the dialogue at the center of the screen and the effects
all around you.

ACCURATE MID-BASS DRIVERS AND SUBWOOFERS:

The 6-1/2 inch mid-bass

drivers incorporate fiberglass reinforced cones along with microcell laminate domes
and surrounds to provide tight and smooth midrange sounds without harshness, stri-
dency, or listener fatigue.  The pair of twelve inch high power subwoofers completes
the experience with earth shattering, deep bass. 

PURE TITANIUM TWEETER: 

This tweeter provides well-defined high frequency out-

put with low distortion, flat and smooth high frequency response, and no break-up in
the audio range.
