Applications:
e Control® 28-1 is a two-way 8” speaker with rich sonic character, wide
coverage, consistent coverage, versatile mounting, and a contemporary high-
design look that ts into a wide range of decors, is makes Control 28-1
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.
e unique InvisiBall mounting hardware is included in with each system,
making short work of permanent installation. e 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 the
deterrence as well. Integrated M6 mounting points for an optional U-bracket
adds to the installation versatility.
e LF driver’s woven berglass cone provides durability and weather capable
performance. e light weight high temperature berglass 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. e 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 o-axis performance, while an FEA-
optimized motor construction and linear suspension spider helps to lower
harmonic distortion.
e HF driver’s low viscosity ferro-magnetic uid increases voice coil cooling
for higher long-term power handling. e 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.
In addition to the driver designs contributing toward a high degree of
weather resistance, the cabinet provides excellent endurance against sun, salt
and moisture. Grilles are heavily zinc-plated and nished in a tough, high-
grade powder coating for rust resistance, and optional MTC-28WMG-1
WeatherMax™ grilles are available for especially dicult environments and to
break up driving rain. Connection is made via weather-capable screw-down
terminals, and the optional MTC-PC2 and MTC-PC3 panel covers are
available to protect the terminal compartment, providing a water-tight sealed
gland-nut entrance (when used with round-jacketed cable within the specied
diameter range).
e frequency response is extremely smooth, resulting in a very natural sound
character, and the response extends down to 45 Hz, providing strong bass
capability. e system is capable of handling 120 Watts continuous pink noise
(240 Watts program) at its 8 ohm setting and is also equipped with a built-in
60 Watt 70V/100V multi-tap transformer for operation on distributed speaker
lines. e combination of high sensitivity and power handling provides high
Max SPL of 112 dB.
e Control 28-1 readily accepts a variety of paints and nishes to match any
décor. Available in black or white (-WH).
