DOCUMENTATION

CONVENTIONS

Thank you for purchasing the JBL

Performance Series P81/P941 In-Wall

Loudspeakers. Designed for discerning

audiophiles, the P81 and P941 offer ver-

satile, easily integrated in-wall loud-

speakers that provide the superior,

uncolored sound that is the hallmark of

JBL loudspeakers. The P81 and P941

reproduce realistic, accurate signals

with minimal coloration and distortion,

making them perfect complements to

JBL Performance front speakers in

multichannel setups. Proprietary trans-

ducers, sophisticated filter networks,

and user-adjustable compensation con-

trols allow the P81/P941 to achieve

remarkable sound quality and perform-

ance befitting the most demanding

home entertainment systems.

The P81 and P941 are also perfectly

suited as front and surround speakers

in complete in-wall setups, or as stereo

pairs in secondary listening spaces, or

for integration with flat-screen televi-

sion home theater installations. Unlike

freestanding loudspeakers, the P81 and

P941 speakers occupy no space in liv-

ing areas and will not detract from the

décor of the listening room. They are

easily mounted in either pre-existing or

new construction projects.

A critical aspect of loudspeaker design,

transducers convert electrical signals

into audible sounds, profoundly affecting

speaker performance. Combining supe-

rior form and function, the P81 and P941

transducers feature a distinctive design

that allows for smoother frequency

response. The cones are constructed

with Organic Ceramic Composite cone

material to reduce dis

tortion, while the

spiders are constructed

of a high-strength

Nomex®blend with optimized geometry

for increased linearity.

A two-way design, the P81 transducers

effectively cover a broad range of fre-

quencies. A 7-1/2-inch (191mm) woofer

delivers highly refined and dynamically

authoritative low frequencies down to

the very lowest octaves. Also, a 1-inch

(25mm) titanium-dome tweeter repro-

duces high frequencies well above

audible levels, with wide dispersion for

open, airy treble.

A three-way design, the P941, in addi-

tion to its 9-inch (229mm) woofer and

1-inch (25mm) tweeter, also features

a 3-1/2-inch (89mm) midrange, which

handles critical mid-band frequencies

with natural tonal balance over a wide

operating range.

An advanced midrange (P941 only)

motor structure includes two high-

grade neodymium magnets placed

at the center of the motor structure,

inside the voice coil, for improved

magnetic shielding. Inside the motor, a

black-plated steel-shield cup facilitates

heat dissipation for higher power han-

dling. An integrated aluminum flux-

stabilization ring minimizes modulation

inside the motor’s static gap flux field,

greatly reducing distortion. A copper ring

inside the motor’s gap reduces distortion

even further. Both rings are optimally

sized and placed to maintain constant

linear voice coil inductance with

forward and backward motions.

The P81 has a high-order filter at

2.8kHz. In the P941, high-order filters at

300Hz and 2kHz optimize loudspeaker

on- and off-axis response, helping

to ensure smooth octave-to-octave

balance and timbral accuracy. The P81

and P941 feature gold-plated binding

posts that accommodate two connec-

tion methods, while separate High-

Frequency Tilt, Low-Frequency Boundary

Compensation, High-Frequency Level

and Listener Axis controls compensate

for less-than-ideal listening room

acoustics and loudspeaker placement.

For more than 50 years, JBL has stood

at the forefront of loudspeaker design.

With extensive research and design

facilities, the JBL Performance Series

P81 and P941 loudspeakers benefit

from cutting-edge tools such as a multi-

channel listening lab for double-blind

listening tests; a laser interferometer

for detailed driver analysis; real ane-

choic chambers for precise tests and

measurements; finite element analysis

for advanced loudspeaker modeling;

and a stereo lithography apparatus for

design verification.

Adding to the proud lineage of JBL’s

Performance Series loudspeakers, the

P81 and P941 further advance JBL’s

reputation as the leading designer

and manufacturer of high-quality,

high-performance loudspeakers.
