JBL Control 28-1 8 Inch 2-Way Speakers High Output Outdoor Pair

High-Output JBL Sound for Larger Indoor and Outdoor Spaces

The JBL Control 28-1 is a high-output 2-way surface-mount loudspeaker designed for foreground music, background music, and paging in larger indoor or outdoor spaces. Sold as a pair, it is well suited to restaurants, patios, gyms, retail spaces, hospitality venues, educational facilities, theme parks, and other areas that need more output and low-frequency extension than smaller surface-mount speakers.

Each speaker combines an 8" woven-fiberglass woofer with a 1" PEI diaphragm tweeter and provides broad 100° × 100° coverage.

Who Should Choose the Control 28-1?

Choose the Control 28-1 when you need stronger output, fuller bass, and broader coverage than a smaller compact surface-mount speaker can provide.

Its built-in 70V/100V transformer and direct 8-ohm THRU mode make it flexible enough for distributed-audio systems as well as conventional low-impedance amplifier setups.

8-Inch Woven-Fiberglass Woofer

The Control 28-1 uses an 8" woven-fiberglass low-frequency driver with a pure butyl rubber surround, Weather-Edge frame protection, high-temperature voice-coil materials, and an optimized motor structure.

The larger woofer helps provide stronger low-frequency output for music-focused spaces and larger listening areas.

1-Inch Fluid-Cooled Tweeter

A 1" PEI diaphragm tweeter with low-viscosity ferro-magnetic fluid cooling handles high-frequency reproduction.

The tweeter is designed for durability and smooth sound while maintaining broad 100° × 100° coverage.

120W Continuous / 240W Program Power

JBL specifies 120W continuous pink-noise power handling for 2 hours, 240W continuous program power, and 480W peak capability.

JBL also publishes a 90W continuous pink-noise rating for 100-hour testing.

These are passive-speaker power ratings. The Control 28-1 requires a compatible external amplifier.

70V and 100V Distributed-Audio Operation

The built-in 60W transformer provides selectable taps for distributed-audio systems:

• 70V: 7.5W, 15W, 30W, or 60W
• 100V: 15W, 30W, or 60W

When using multiple speakers on a 70V or 100V amplifier, add the selected tap wattages and allow appropriate amplifier headroom.

Direct 8-Ohm THRU Mode

The Control 28-1 can bypass the transformer using its THRU position for direct 8-ohm operation with a compatible low-impedance amplifier.

Confirm total speaker impedance before connecting multiple speakers to the same amplifier channel.

100° × 100° Coverage

JBL specifies 100° horizontal × 100° vertical coverage, helping distribute sound broadly and consistently across the listening area.

Actual coverage depends on mounting height, aiming, listener distance, environmental noise, and room or outdoor acoustics.

45Hz–20kHz Frequency Range

JBL specifies a 45Hz–20kHz frequency range at -10dB and a 62Hz–16kHz frequency response at ±3dB.

This gives the Control 28-1 stronger low-frequency extension than many smaller surface-mount speakers while still supporting clear speech and paging.

Included InvisiBall Wall Mounts

JBL's InvisiBall mounting system is included for adjustable wall installation while keeping most mounting hardware visually hidden.

An optional MTC-28UB-1 U-bracket is available for installations that require a different mounting method.

Indoor and Outdoor Weather Resistance

The standard Control 28-1 is rated IP44 and uses weather-resistant transducers, enclosure materials, and a durable grille for suitable indoor and outdoor installations.

For more demanding environments, JBL specifies IP55 capability when the optional MTC-28WMG-1 WeatherMax grille and compatible MTC-PC2 or MTC-PC3 protective panel cover are installed.

Screw-Terminal Connections

The Control 28-1 uses screw-down terminals that accept bare wire up to 12 AWG or compatible open lugs.

Use appropriately rated speaker wire for the amplifier type, cable length, and installation environment.
