JBL Control 424LP

The JBL Control 424LP two-way coaxial ceiling loudspeaker features a 4” woofer and integrated low profile enclosure that is ideal for installation in where ceiling plenum space is shallow. Compatible with both 70V/100V and low impedance circuits, the 424LP is rated at 60W on the 16 Ohm setting and has a multitap 30 Watt transformer for 70/100V line use.

Part of the JBL Series 400 enhanced coverage ceiling speaker range, the Control 424LP offers extremely wide 130° coverage angle and integrated CRBI technology provides consistent coverage and full, rich sound throughout the listening area. 

A full-face magnetic grille blends seamlessly with modern decors and optional black and square grilles are available.

Mechanical improvements include redesigned terminal covers with top and side cable entry ports and an extremely reliable new dogear design that works with a wide range of ceiling thicknesses.

The Coplanar RBI™, or CRBI™ delivers an especially smooth sound character that remains consistent, clear, and pleasant across a wide coverage area. It reduces on-axis hot spots and off-axis cold spots and improves the listening experience for users as they move throughout a space. This enhanced coverage results in fewer speakers, amplifier channels, and project costs, required to cover a space.

  • Coaxially mounted 100 mm (4 in) woofer and 19 mm (0.75 in) soft-dome tweeter
  • Integrated low-profile backcan (under 100 mm deep) for use in shallow ceiling spaces.
  • CRBI™ technology for consistent 130° coverage across the listening area
  • Built-in 70V/100V multi-tap transformer, plus 16-ohm direct input
  • Full-face, easily paintable magnetic grilles
  • Top and side exit cable entry options
  • Robust and adaptable dogears for wide range of ceiling thicknesses
  • IP33 rated
