2370A Flat-Front Bi-Radial Horn
Key Features:
• 90 x 40 nominal dispersion
• Uniform horizontal on and off axis frequency response
• Precise horizontal pattern control
• Full horn loading to 630 Hz
• Flat front, compact size, and lightweight construction
• 25 mm (1 in) throat entry
The JBL Model 2370A is a compact Bi-Radial horn with a nominal coverage pattern of 90 horizontal x 40 vertical. The horn provides uniform on and off axis frequency response in the horizontal plane from 630 Hz to beyond 16 kHz. The horn's small vertical mouth dimension was chosen to allow a gradual narrowing of the vertical coverage pattern with increasing frequency. This provides acoustic equalization of the frequency response of the horn in the horizontal plane and compensates for the falling power response of all compression drivers. Should constant vertical pattern control be required, two or more 2370As may be stacked to restore full Bi-Radial performance.
