INTRODUCTION
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 distortion, 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.
