JBL CONTROL 28-1L High Output Indoor/Outdoor Background/Foreground Speaker (Pair, Black)

Product Overview

The JBL Control 28-1L is the 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. 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 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 is the same speaker with onboard taps.

Frequently Asked Questions

How is the 28-1L different from the Control 28-1?
The 28-1L is the low-impedance-only version — 8 ohms with no built-in 70V/100V transformer. Choose it for low-impedance amplifier zones; choose the 28-1 if you need to run on 70V or 100V distributed lines.

Is the Control 28-1L 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.

What mounting hardware is included?
The InvisiBall aimable wall-mounting system is included, with adjustment through a hidden access point behind the logo badge and a secondary safety attachment loop on the back panel.

What protective high-pass filter is recommended?
JBL recommends a 45 Hz high-pass (24 dB/oct) for 8-ohm operation to protect the driver at high output.

What warranty and support apply?
The Control 28-1L carries JBL Professional's manufacturer warranty. For amplifier matching, weatherization, and integration support, contact our team at sales@creationnetworks.net or browse the full JBL Professional collection.
