Enhanced Two-Way Audio Performance

Designed for clear, balanced sound reproduction, the JBL Control 424C/T features a 4-inch woofer and 0.75-inch soft-dome tweeter in a coaxial configuration for improved phase alignment and sonic consistency.

With a frequency range of 75 Hz to 18 kHz, the speaker delivers detailed highs, articulate midrange, and controlled low-frequency response for both speech and music applications.

CRBI™ Technology with Wide 130° Coverage

The Control 424C/T provides a broad 130° conical coverage pattern, ensuring smooth and consistent sound distribution throughout commercial environments.

JBL’s proprietary CRBI™ technology delivers exceptionally even tonal balance and intelligibility across a wide listening area, helping maintain consistent sound quality both on- and off-axis. Its CRBI™ waveguide design minimizes audio hot spots and dead zones, enabling integrators to achieve consistent coverage with fewer speakers while maintaining excellent speech intelligibility and musical clarity.

Flexible Installation & System Integration

Designed for efficient commercial installation, the JBL Control 424C/T features an integrated enclosure optimized for installation in most ceiling plenum spaces.

The built-in multi-tap transformer supports both 70V/100V distributed systems and 16Ω low-impedance operation, offering flexible integration for commercial audio installations.

Modern Architectural Design

The JBL Control 424C/T features a full-face, bezel-less magnetic grille that blends elegantly into modern architectural environments. Its refined appearance makes it ideal for architecturally sensitive commercial installations.
