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.
The horn's exceptionally consistent horizontal dispersion eliminates the midrange narrowing and high frequency beaming problems typically associated with conventional horn designs. Additionally, the 2370A's highly predictable performance greatly simplifies cluster design. The need for horn overlapping is minimized and lobing and comb filter effects are virtually eliminated.
