EMINENCE LH 290S – Bi-Radial Horn 90 x 40° 297 x 168 mm

1" Bi-Radial-Horn 90 x 40°- 297 x 168 mm

These specially designed series of bi-radial and constant directivity horns offer a very precise dispersion pattern. Adam Hall horns are molded from polyamide PA 6.6. This high grade material combines excellent acoustic behavior and mechanical ruggedness. The horn is constructed from two molded parts: the horn body and the flange. Both are joined with six screws. This specially reinforce the critical area of throat / flange.
