Design Overview

The JBL 2395 represents the ultimate expression of JBL's slant-plate lens technology, designed for applications requiring exceptionally wide horizontal coverage:

Extended Lens: 914mm (36") wide slant-plate lens creates 140° horizontal dispersion
Elliptical Horn: 300mm (12") elliptical exponential horn controls 45° vertical pattern
No Additional Baffle Required: Does not require baffling for use above 800 Hz
Plate End Clearance: Lens plate ends must not be obstructed for proper high-frequency operation

Low Frequency Operation

While rated for use above 800 Hz, the 2395 can operate down to 500 Hz in:

Motion picture sound systems
Applications where vertical pattern control is not essential
Systems with proper vertical plane baffling

Compatible Drivers

The 2395 features a 50mm (2 inch) throat entry:

Native 2" drivers: JBL 2420, 2421, 2441 series compression drivers
With Adapter: JBL LE85, 2425 and other 1" drivers using Model 2327 throat adapter

Applications

The 2395's extremely wide 140° horizontal pattern makes it ideal for:

Cinema sound systems requiring broad audience coverage
Large venue sound reinforcement
Theater and auditorium installations
Applications with wide seating areas
Professional monitoring in large control rooms

Physical Considerations

The 2395 is a substantial horn assembly:

Width: Nearly a meter (36") wide - requires significant baffle or cabinet space
Weight: 16.8 kg (37 lb) - requires robust mounting hardware
Depth: 476mm (18¾") - substantial cabinet depth required
Clearance: Lens plate ends must remain unobstructed
