JBL Control 23-1 3 Inch Compact 2-Way Indoor Outdoor Speaker Pair

Compact JBL Sound for Indoor and Outdoor Spaces

The JBL Control 23-1 is an ultra-compact 2-way surface-mount loudspeaker designed for background music, foreground music, and paging in indoor or outdoor spaces. Sold as a pair, it is well suited to patios, restaurants, retail stores, hospitality areas, fitness spaces, educational facilities, and other locations where discreet speaker placement matters.

Each speaker combines a 3" woven-fiberglass low-frequency driver with a 0.5" PEI high-frequency driver and provides wide 100° × 100° coverage.

Who Should Choose the Control 23-1?

Choose the Control 23-1 when you need compact speakers that can blend into smaller indoor or outdoor spaces without sacrificing clear speech or music playback.

The combination of wide coverage, flexible mounting, 8-ohm operation, and built-in 70V/100V transformer support makes the Control 23-1 useful for both conventional amplifier systems and distributed-audio installations.

3-Inch Woven-Fiberglass Woofer

The Control 23-1 uses a 3" woven-fiberglass woofer with a pure butyl rubber surround and JBL Weather-Edge frame protection.

The low-frequency driver also uses a high-temperature Kapton voice-coil former and FEA-optimized motor structure to support consistent performance in compact installations.

0.5-Inch Fluid-Cooled Tweeter

A 0.5" PEI diaphragm tweeter handles the high frequencies. JBL uses ferro-magnetic fluid around the tweeter voice coil to improve cooling and durability.

50W Continuous / 100W Program Power

JBL specifies 50W continuous pink-noise power handling for 2 hours, 100W continuous program power, and 200W peak capability.

These are passive-speaker power ratings. The Control 23-1 requires a compatible external amplifier.

70V and 100V Distributed-Audio Operation

The built-in 15W transformer provides selectable taps for distributed-audio systems:

• 70V: 1.8W, 3.7W, 7.5W, or 15W
• 100V: 3.7W, 7.5W, or 15W

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

8-Ohm THRU Mode

The Control 23-1 can also bypass the transformer for direct 8-ohm operation with a compatible amplifier or AV receiver.

Confirm the total speaker load before connecting multiple speakers in low-impedance mode.

100° × 100° Coverage

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

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

70Hz–20kHz Frequency Range

JBL specifies a 70Hz–20kHz frequency range at -10dB and a 95Hz–19kHz frequency response at ±3dB.

This makes the Control 23-1 suitable for spoken-word paging and general background or foreground music.

Included InvisiBall Mounting System

Each speaker includes JBL's InvisiBall wall-mounting system for compact, adjustable installation.

Optional accessories include the MTC-23UB-1 U-bracket and MTC-23CM ceiling-mount InvisiBall adapter for additional mounting flexibility.

Indoor/Outdoor Weather Resistance

The standard Control 23-1 is rated IP44 and is designed with a weather-resistant enclosure and transducers for suitable indoor and outdoor use.

For more demanding environments, JBL specifies IP55 performance when the speaker is used with the optional MTC-23WMG-1 WeatherMax grille and compatible MTC-PC2 or MTC-PC3 protective panel cover.

Screw-Terminal Connections

The Control 23-1 uses a screw-down terminal strip that accepts bare speaker wire up to 12 AWG or compatible open lugs.

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