Control Contractor Series Surface Mount Speaker: The Control
23-1 is a two-way surface-mount loudspeaker with rich sonic character, wide
coverage, consistent coverage, versatile mounting, and a contemporary design
that fits into a wide range of decors. This makes Control 23-1 an excellent
choice for a wide variety of applications, including retail stores, restaurants,
health clubs, theme parks, educational facilities, hospitality, music cafes,
leisure venues, and anywhere where a top quality high-output indoor/ outdoor
foreground/background music (and/or paging) speaker is required.
Note: All JBL Control Contractor loudspeakers (both ceiling
speakers and surface-mount models) are designed with a similar sonic
signature, allowing for mixing and matching of the various models within an
application, providing a similar tonal character throughout the entire
Two-Way Speaker Design: The Control 23-1 indoor/outdoor
speaker employs a 0.5" PEI horn-loaded tweeter and a 3" woven fiberglass cone
woofer for high fidelity sound performance. The horn-loaded 0.5" tweeter features
a PEI diaphragm, low-viscosity ferro-magnetic fluid, and a lightweight Kapton
voice coil former. The 3" woven-fiberglass cone features a pure butyl rubber
surround with Weather-Edge frame protection, high-temp fiberglass voice coil
former, high-temp voice coil wire, optimized cone geometry, linear suspension
spider, and FEA optimized motor structure. Its speaker design ensures excellent
sound character, providing pleasant, enveloping sound throughout the listening
- 0.5" Tweeter: The horn-loaded 1" tweeter's low viscosity
ferro-magnetic fluid increases voice coil cooling for higher long-term power
handling. The PEI diaphragm delivers a smooth high frequency sound quality.
A light weight Kapton voice coil former increases durability while providing
better high frequency response extension. All these factors also contribute
toward making the driver especially rugged for outdoor and other stressful
applications. The Control 23-1's horn-loaded tweeter provides an even 100° x
100° coverage area to ensure excellent sound quality throughout the
- 3" Woofer: The 8" woven fiberglass cone woofer provides
durability and weather capable performance. The light weight high
temperature fiberglass voice coil former and high temperature voice coil
wire ensures stable performance under long-term high-power working
conditions while also providing high sensitivity and high power capability.
The pure butyl rubber surround delivers clean sound and ruggedness, while
terminating its circumference in JBL's WeatherEdge (a seamless, rubberized
extension of the woofer surround that provides added protection to critical
transducer elements). Cone geometry is optimized for smooth frequency
response and good off-axis performance, while an FEA optimized motor
construction and linear suspension spider helps to lower harmonic distortion
Weather Resistance Enclosure: In addition to the driver
designs contributing toward a high degree of weather resistance, the cabinet
provides excellent endurance against sun, salt and moisture. Weather resistance
is maximized by the Control 23-1 speaker's high-impact polystyrene (HIPS)
cabinet and heavily zinc-plated grille. The Control 23-1 is available in a black
or white finish; the cabinet and grille also accepts a variety of paints to
match any décor. The Control 23-1 indoor/outdoor speaker is IP-44 rated and
exceeds MilSpec 810 for humidity, salt-spray, temperature & UV. It also passes
MilStd-202F for salt spray and ASTM G85 for acid-air plus salt spray.
70V/100V Compatible: Control 23-1 includes a 30W multi-tap
transformer for use in either 70V or 100V distributed-line systems. Taps are
selected with a rotary switch located on the rear-panel.
- 70V Taps: 15W, 7.5W, 3.7W, 1.8W
- 100V Taps: 15W, 7.5W, 3.7W
Note: The Control 23-1 also features an 8-ohm pass-through
Screw-Down Terminals: Speaker wire connection is made via
weather-capable, screw-down terminals.
Mounting Options: The unique InvisiBall mounting hardware is
included, making short work of permanent installation. The InvisiBall mounting
method provides a high degree of both vertical and horizontal rotation. And,
because InvisiBall adjustments are made through a hidden access behind the logo
badge, the grille never needs to be removed and there exists a high degree of
theft deterrence as well. Integrated M6 mounting points for an optional
U-bracket adds to the installation versatility.
SonicGuard Protection: JBL's exclusive SonicGuard overload
protection is virtually inaudible to the listener, ensuring reliability while
providing full fidelity sound.
