JBL 2370A, Flat-Front Bi-Radial HornCondition:* New Surplus Stock, In OEM Packaging. Open Box. As Pictured. Additional Notes:* The JBL Model 2370A is a compact Bi-Radial Horn with a nominal coverage pattern of 90 Horizontal x 40 Vertical.* Speaker Impedance: 8 Ohm* 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.* 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 Inch) Throat EntryJBL2370A
