Control®128W/WT
Premium
In-Wall
Loudspeaker
Key Features:
cComponents:
• 200 mm (8 in) polymer-coated
aluminum-cone woofer with pure butyl
rubber surround.
c • 25 mm (1 in) pure-titanium dome low-
diffraction swivel aimable titanium
tweeter.
cHigh-slope crossover for natural midrange
sound.
cExtended bandwidth performance of
30 Hz – 20 kHz.
c60W continuous (120W program, 240W
peak) power handling (128W).
The Control 128W is a premium in-wall
speaker within the JBL Professional Control®
Contractor line designed for applications such
as foreground music, boardrooms, reception
areas, airports, convention centers, cruise
ships, retail outlets, restaurants, museums,
surround locations, or any critical listening
application where top performance from a
loudspeaker with minimal visual impact is
required.
The high-performance woofer features a
polymer-coated aluminum cone for high
performance down to 30 Hz and pure butyl
rubber surround for long-life and high
reliability along with extended-polepiece
magnet design for long excursion and tight,
low bass. The pure titanium dome high
frequency driver is loaded with a built-in
EOS™ (Elliptical Oblate Spheroidal)
waveguide for low distortion and a smooth
frequency response. A low-diffraction swivel-
mounting system enables the user to direct
high frequencies where required without the
diffraction distortion inherent in other aimable
tweeter designs. A high-slope crossover
network maintains natural midrange sound
and produces more even coverage
throughout the listening area. The optional
Control 128WT version includes a multitap
transformer for 70V/100V systems.
The Control 100 Series speakers are voiced
similarly to other JBL Control Contractor
models, allowing mixing with surface-mount
and in-ceiling speakers within a single
listening space. The premium sound quality
makes these loudspeakers ideal for critical
listening environments, yet they are high
power and rugged enough to handle venues
requiring high-SPL, heavy duty-cycle music.
The speaker fits into the wall space of
ordinary stud-wall construction. An optional
rough-in frame is available for installing the
speakers into standard stud walls in new-
construction projects. As is the case with all
Control Contractor speakers, the baffles and
grilles are paintable to match any décor.

JBL continually engages in research related to product improvement. Some materials, production methods and design
refinements are introduced into existing products without notice as a routine expression of that philosophy. For this
reason, any current JBL product may differ in some respect from its published description, but will always equal or
exceed the original design specifications unless otherwise stated.
Rear Air Cavity Considerations
The Control 128W is designed to function over a wide span of rear air cavity sizes within
the wall. The optimum air cavity (sometimes called “loading volume”) for fullest low-
frequency performance is between 40 to 80 liters (1.4 to 2.8 cu ft). In a wall with studs
located 16-inches on-center, this approximately equals a 46-inch to 92-inch high space. It is
recommended that the air cavity behind the speaker be sealed by the use of silicone sealant
or similar material to help create an air-tight seal and minimize wall noise.
