INTRODUCTION
Congratulations on purchasing this JBL Synthesis®Three Array™home theater speaker. This product represents the
synthesis of everything that JBL has learned about the emotional power of audio and video in sixty 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 Array
speaker systems feature the following:
THX ULTRA2™-LICENSED HOME AUDIO SYSTEM: When used with a THX
speaker system will deliver a state-of-the-art THX home theater experience to your living room. 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.
ULTRAHIGH-FREQUENCY COMPRESSION DRIVER: 1" (25mm) Pure-titanium compression driver with aluminum
edge-wound voice coil and 2" (51mm) neodymium motor assembly
high-frequency response to exceed SACD™and DVD-Audio specifications.
, mounted in a constant-directivity horn for extended
High-Power Compression Horn: Horns are commonplace in movie theaters across the world, because of
their high power handling and well-defined high-frequency output. The horns employed in SAM3 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" (165mm) mid-bass drivers incorporate many
of JBL’s patented technologies – such as Symmetrical Field Geometry
(SIM) and Vented Gap Cooling
midrange sound without harshness, stridency or listener fatigue. From two to as many as four 12" or 15" (305mm or
380mm) high-power subwoofers complete the experience with earth-shattering, deep bass.

COMMON VOICING: Synthesis Three Array uses common voicing across the front three channels. Since identical
drivers are used, each speaker has the same tonal qualities, thus as a sound is panned from one side to the other,
there will be no change in timbre.
MAGNETIC SHIELDING: All front speakers are magnetically shielded, allowing you to place them near video mon-
itors without generating interference or distorting the picture.
DUAL “INSIDE” NEODYMIUM, SHIELDED MOTOR STRUCTURE: The magnetic material is placed at the
center of the motor structure, INSIDE the voice coil diameter. This inverted dual-magnet configuration improves
magnetic shielding even further, reducing the extraneous magnetic field, and offers increased acoustic output.
DEEP-ANODIZED CONE
together with the motor features, helps to reduce midband distortions to very low levels (approximately 50dB to 60dB
below the fundamental signal driven at 100dB output).

TWO-STAGE PHASE PLUG: The phase plug is a key element in this compression driver. The accuracy of the phase
plug geometry is most important to achieve a wide and flat frequency response. The pressure distribution in the phase
plug is manipulated by adjustments to the number and width of the slots and even the plug inside streamline is optimized to achieve a coherent pressure front across the operating range at the exit of the phase plug.
SYMMETRICAL INDUCTANCE MODULATION (SIM): The flux-stabilizing ring and copper gap ring are also opti-

asymmetrical inductance modulation leads to even further distortion reduction and improved vocal clarity

SPEAKER PLACEMENT
Positioning your loudspeakers properly is critical in order to achieve the
sonic performance of a home theater. Please read the following section
for guidance in correct and optimal placement.
LEFT AND RIGHT SPEAKERS: If you have purchased a Synthesis Three
Array Digital Home Theater System, then the model SAM3VA will serve as
your front left and right main speakers.
Since the left and right speakers have been designed for maximum localization
of sound, they should be placed with the center of the speakers at about the
same height on screen as the actors would be, to aid in the illusion that the
actors’ voices are coming directly from their on-screen images. Ideally, the
speakers will be placed about 45 degrees apart from each other,
from the listening position, so that the distance between the speakers
same as each speaker’s distance from the listener (see Figure 1).

installation in order to take advantage of its sound-dispersion characteristics.
If you mount it horizontally, it will not provide the correct dispersion pattern.
If the speaker is being used with a perforated projection screen, it should be
mounted behind the center of the screen (see Figure 2). If a nonperforated
projection screen, plasma display or other fixed video device is being used
in the installation, the preferred center speaker is the model SAM3HA (below).
A:
If you have purchased the vertical channel speaker (model
A) for the center position, be sure to place it vertically during
Figure 2.
SAM3HA: If you have purchased the horizontal channel speaker (model SAM3HA) for the center position, be sure
to position it horizontally during installation in order to take advantage of its
sound-dispersion characteristics. If you mount it vertically, it will not provide
the correct dispersion pattern. Although the preferred speaker model to be
used with a perforated projection screen is the vertical model SAM3VA
(above), the SAM3HA horizontal speaker may be used instead and should be
mounted behind the center of the screen. If a nonperforated projection
screen, plasma display or other fixed video device is being used in the
installation, then the recommended location is directly below and as close
as possible to the video display (see Figure 3), although the inverse of this
method will work also.
