The JBL Control 23-1L is a compact, two-way indoor/outdoor speaker designed for background or foreground music and paging. It features the proprietary InvisiBall mounting system for flexible positioning and is rated IP-44 for weather resistance, which can be upgraded to IP-55 with optional accessories. This guide provides essential information on mounting, wiring, and technical specifications.
Product Overview
The Control 23-1L is built for durability and high-fidelity sound. Key components include a 3-inch woofer with a woven fiberglass cone and a 1/2-inch PEI diaphragm tweeter with fluid cooling. The enclosure is made of high-impact polystyrene (HIPS) and is available in black or white.
Installation
The speaker includes the InvisiBall wall-mounting system, which allows for significant vertical and horizontal rotation. Adjustments are made through a hidden access point behind the logo badge, meaning the grille does not need to be removed for installation or adjustment.
- Mounting: Use the included InvisiBall system for wall mounting.
- Optional Brackets: For alternative mounting, the speaker features integrated M6 mounting points compatible with the optional MTC-23UB-1 U-bracket.
- Safety: A secondary safety attachment loop point is located on the back panel.
Connections
The speaker utilizes a weather-capable screw-down terminal strip for audio input.
- Wire Compatibility: Accepts bare wire up to 12 AWG (2.5 mm²) or open lugs (#6, #8, or #10).
- Protection: For enhanced weather protection, optional MTC-PC2 or MTC-PC3 panel covers can be installed to provide a water-tight sealed gland-nut entrance.
Environmental Protection
The speaker is IP-44 rated per IEC529. To achieve an IP-55 rating, you must install the optional MTC-23WMG-1 WeatherMax grille along with either the MTC-PC2 or MTC-PC3 panel cover. The unit exceeds MilSpec 810 standards for humidity, salt spray, temperature, and UV exposure.
