2392, 2393, 2394 Large Format Optimized

Aperture Bi-Radial® Horn Family

Professional Series

Key Features:

cOptimized ApertureTM horn design provides very low distortion at high sound pressure levels.

cLarge format horn family provides uniform on and off axis frequency response from 300 Hz to above

3 kHz.

cControlled horizontal and vertical pattern in 90° x 50°, 60° x 40°, and 40° x 30° coverage patterns.

c76mm (3 in) throat entry.

JBL models 2392, 2393, and 2394 are valuable additions to JBL’s family of Bi-Radial® horns, providing uniform coverage control over the bandwidth of 300 Hz to above 3 kHz, allowing precise control of critical vocal range energy. These large format horns provide extremely low distortion at typical peak sound pressure levels of up to 145 dB-SPL at 1m (model 2394).

Optimized Aperture -

The clear and uncolored sound character of the 2390-Series horns is accomplished by coupling the compression driver phase plug to a unique horn throat geometry, resulting in the elusive combination of extremely low throat distortion with high air movement capability. These horn designs were verified through the use of advanced technology, including finite element analysis, boundary element analysis and extensive computer modeling via proprietary JBL horn design software.

Components and Accessories -

The 2390-Series of horns were designed to be used exclusively with the 2490H midrange compression driver. The diaphragm for this driver utilizes a three-dimensional diamond pattern surround and a pure titanium diaphragm for rigidity and freedom from breakup modes. With its 200 watt continuous program rating and optimized phase plug design for low distortion, smooth response and wide bandwidth, the 2490H is ideal for use in high level sound pressure applications.

The 2510 Mounting Bracket is recommended for suspension of the horn/driver combination. The 2510 “sandwiches” between the horn and driver providing multiple pickup points, including a slot that allows front/back alignment.

Optional Weather-Resistant versions are available, providing a 3-layer weather resistant grill and sealed chamber for the driver.
