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.
