Description
The JBL 4732 Three-Way ScreenArray™ Cinema Loudspeaker System is designed for critical film sound reproduction in medium to large cinema environments. Its true three-way ScreenArray™ design delivers maximum output, optimal coverage, and minimum distortion for a powerful and immersive cinema audio experience.
The JBL 4732 supports triamplified (4732T) and biamplified operation, providing flexibility for professional cinema installations. It features Second Generation Optimized Aperture Waveguide Technology, SSC™ Screen Spreading Compensation, and Focused Coverage Technology™ to deliver extremely uniform frequency response, controlled coverage, and ultra-low distortion.
Its flat-front waveguide design and shallow profile make it suitable for easy baffle-wall installation while requiring minimal space behind the cinema screen. The system ships fully assembled for convenient deployment.
