The JBL Control 28-1 is a high-output indoor/outdoor surface-mount loudspeaker built for background and foreground audio in demanding commercial AV environments. With weather-resistant construction and an IP-44 rating, this commercial loudspeaker performs reliably in covered patios, atriums, retail exteriors, and multi-purpose spaces. Integrated 70V/100V transformer taps allow direct connection to distributed audio systems, while an 8-ohm bypass supports low-impedance use. The included InvisiBall mounting system delivers secure, aimable installation on walls and ceilings.
The Control 28-1 is an 8″ two-way surface-mount speaker engineered for installations that require both high output and long-term durability. Its 200 mm woven-fiberglass LF driver uses a pure butyl rubber surround with Weather-Edge frame protection and a high-temperature voice coil, paired with a 25 mm PEI-diaphragm tweeter for clear program audio and speech. The High Impact Polystyrene (HIPS) enclosure with 10% glass fill resists UV fade, and the unit exceeds MilSpec 810 for humidity, salt-spray, temperature, and UV exposure, making it suitable for semi-exposed outdoor commercial deployments. Integrated transformer taps support 70V (60/30/15/7.5 W) and 100V (60/30/15 W) distributed lines, with an 8-ohm THRU setting for direct low-impedance operation. The included InvisiBall wall-mounting system provides aimable positioning with a secondary safety attachment point, and screw-down terminal connectors accept bare wire or lugs. This makes the Control 28-1 a practical choice for integrators specifying weather-resistant distributed audio across exterior walkways, courtyards, and high-traffic indoor spaces.
