Product Overview

The JBL Control 28-1-WH is the white-finish 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. 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.

Product Description

The Control 28-1-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 outdoor 70V/100V surface-mount speaker, it provides integrated transformer taps for 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. For projects that run only low-impedance lines, the JBL Control 28-1L offers the same driver platform without the onboard transformer.

Frequently Asked Questions

Is the Control 28-1-WH suitable for outdoor installation?
Yes. It carries an IP-44 rating (IP-55 with the optional WeatherMax grille and panel cover), exceeds MilSpec 810 for humidity, salt-spray, temperature, and UV, and is designed for covered exterior and semi-exposed environments.

Does it work with 70V and 100V distributed audio systems?
Yes. It includes integrated 70V (60/30/15/7.5 W) and 100V (60/30/15 W) transformer taps, plus an 8-ohm THRU setting for direct low-impedance connection.

How does it differ from the Control 28-1L?
The 28-1 (and 28-1-WH) includes an integrated 70V/100V transformer; the 28-1L is the low-impedance 8-ohm version of the same speaker without the onboard transformer.

What protective high-pass filter is recommended?
JBL recommends a 45 Hz high-pass (24 dB/oct) for 8-ohm operation and the 15W/7.5W taps, 55 Hz for the 30W tap, and 65 Hz for the 60W tap to protect the driver at high output.

What warranty and support apply?
The Control 28-1-WH carries JBL Professional’s manufacturer warranty. For tap planning, weatherization, and integration support, contact our team at sales@ or browse the full JBL Professional collection.
