JBL Professional Control 424LP

Grandes images

The JBL Control 424LP is a two-way coaxial ceiling loudspeaker, featuring a 4” woofer and a low-profile enclosure that is ideal for applications where ceiling plenum space is restricted. Integrated CRBI™ technology provides 130° of consistent, full, rich sound character that closely matches that of the Control 424C/T. 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. Like all Control 400 Enhanced Coverage models, the Control 424LP includes a transformer to support both 70V/100V and low impedance applications.

Superior Sonic Performance

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.
Efficient, Flexible Installation

Various Control 400 Enhanced Coverage Series mounting enhancements improve installation repeatability and safety while reducing installation time. Redesigned terminal covers provide both top and side cable entry ports and can be secured without tools thanks to captive hand-screws. The captive dogear design is extremely reliable and works with a wide range of ceiling thicknesses.
Esthétique Affinée et Moderne

Les grilles magnétiques à face pleine offrent un look épuré et affiné répondant aux sensibilités du design architectural moderne. Elles sont équipées de câbles de sécurité qui se montent directement dans le baffle pour assurer une tranquillité d'esprit. Des grilles d'accessoires optionnelles de couleur noire et carrées sont également disponibles pour offrir une polyvalence de conception supplémentaire.
