Product Overview

The JBL Control 28-1L-WH is the white-finish, low-impedance (8-ohm) version of JBL’s 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 on covered patios, atriums, retail exteriors, and multi-purpose spaces, and the white enclosure blends into light architecture. It runs as a straight 8-ohm speaker with no onboard transformer, making it a cost-effective choice for low-impedance amplifier zones. The included InvisiBall mounting system delivers secure, aimable installation on walls and ceilings.

Product Description

The Control 28-1L-WH 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. As an 8-ohm outdoor surface-mount speaker, it omits the 70V/100V transformer found on the standard model it runs at 8 ohms only, handling 240 W continuous program (120 W continuous pink noise, 480 W peak) at a 112 dB maximum SPL (118 dB peak). The included InvisiBall wall-mounting system provides aimable positioning through a hidden access point behind the logo badge, with a secondary safety attachment point, and screw-down terminal connectors accept bare wire or lugs. For projects that need distributed 70V/100V operation, the transformer-equipped JBL Control 28-1-WH is the same speaker with onboard taps.
