Jbl Professional Control 24CT 4 in 2-way Coaxial Speaker

Product Description

The JBL PROFESSIONAL CONTROL 24CT is a 4-inch, 2-way coaxial in-ceiling speaker designed for commercial and residential distributed audio installations. The coaxial driver configuration combines the woofer and tweeter on a single axis, producing coherent, wide-dispersion sound from a compact ceiling cutout. This type of speaker is typically specified by low-voltage audio contractors, systems integrators, and AV technicians working in background music, paging, or speech-reinforcement applications. The CT designation indicates suitability for 70-volt and 25-volt constant-voltage distributed audio systems, which are standard in commercial environments.

This speaker is suited for drop-ceiling and hard-lid ceiling installations in small-to-medium commercial spaces such as retail environments, restaurants, offices, hotel corridors, and similar venues. It is also used in residential whole-home audio systems where compact form factor and clean aesthetics are priorities. The 4-inch driver size targets installations where ceiling cavity depth is limited or where speaker spacing requires a smaller footprint than a standard 6.5-inch unit.

Key Features

• 4-inch 2-way coaxial driver for coherent, point-source sound reproduction
• CT-rated for 70-volt and 25-volt constant-voltage distributed audio systems
• In-ceiling form factor suits both drop-ceiling and hard-lid installations
• Compact driver size allows tighter speaker spacing or use in shallow ceiling cavities
• Sold individually (1 speaker per unit)

Compatibility

Designed as an OEM-style in-ceiling speaker for use with 70-volt and 25-volt constant-voltage amplifier systems common in commercial distributed audio installations.

Installation Notes

Installation should be performed by a qualified low-voltage audio contractor or licensed electrician in jurisdictions that require it. Power down the amplifier and verify zero signal output before making any wiring connections. In-ceiling speaker installations in commercial occupancies may be subject to local fire and building codes governing plenum-rated wiring and backbox requirements — verify applicable codes before rough-in. Do not exceed the amplifier tap wattage rating specified for the transformer setting used.
