*Patents pending worldwide The Control 23 is the most compact of JBL Professional’s Control Contractor Series indoor/outdoor loudspeakers making it a perfect choice for patios, foyers, retail or other applications where foreground/ background music and paging are required, with minimum aesthetic impact.
The unique and global patent pending InvisiBall ® mounting hardware is included in each system and makes short work of permanent installation. The InvisiBall mounting method adds the benefit of vertical rotation of up to 37° off-axis and horizontal rotation of up to 44° off-axis. Because InvisiBall adjustments are made through a hidden access behind the logo badge, the grill never needs to be removed and there exists a high degree of theft deterence as well.
The Control® 23 readily accepts a variety of paints and finishes to match any decor. Weather resistance is maximized by coating the woofer cone in polypropylene and terminating its circumference in JBL’s WeatherEdge™, a seamless, rubberized extension of the woofer surround that provides added protection to critical transducer elements. The polycarbonate tweeter diaphragm is reinforced with a thin film of titanium for added rigidity and endurance against sun, salt and moisture. Zinc plated grilles resist rusting in the harshest conditions. Available in black (Control 23) and white (Control 23-WH).
The loudspeaker shall consist of a 90 mm (3-1/2 in) low frequency transducer, 13 mm (1/2 in) high frequency transducer, and frequency dividing network installed in a ported enclosure. The low frequency voice coil shall be 19 mm (3/4 in) in diameter. Performance specifications of a typical production unit shall be as follows: Measured sensitivity (SPL at 1 m [3.3ft] with 2.83V input, averaged from 500 Hz to 1.5 kHz) shall be at least 86 dB-SPL. Usable frequency response shall extend from 85 Hz to 22 kHz (10 dB below rated sensitivity, in half-space, with no external equalization). Nominal impedance shall be 8 ohms. The frequency dividing network shall have a crossover frequency of 3.5 kHz. Rated power capacity shall be at least 50 watts continuous program power, defined as 3 dB above a test signal of filtered random noise conforming to international standard IEC268-5 (shaped pink noise with a peak-to-average ratio of 6 dB), for 100 continuous hours duration. The system shall be protected against damage from occassional overpowering via full range series lamps that limits the power to the network and transducers. The high frequency transducer shall be hornloaded to more evenly cover a nominal 90° horizontal by 90° vertical area. The enclosure shall be constructed of high-impact polystyrene for protection against the elements in outdoor applications, and for paintability. The grille shall be completely zinc-coated for resistance against rusting, shall be bake-painted black, and shall be secured via screws to keep it in place when facing downward. The low frequency transducer shall have a polypropelene cone and a butyl rubber surround which shall extend seamlessly over the edge of the speaker frame for protection against the elements. The high frequency transducer shall be constructed of polycarbonate, reinforced with a titanium film for additional weather resistance. The system shall withstand Mil Spec 810 testing with specified time durations for exposure to the following environments with no effect on its acoustical performance
