Description
The Beyma SPL90FE is a 1.4-inch-exit ferrite compression driver designed for high-output upper-midrange and high-frequency reproduction through a compatible horn or waveguide. Its large 2.84-inch voice coil and PM4 polymer diaphragm support substantial output and thermal capacity.
The 8-ohm driver is rated for 60 watts AES, with 109 dB sensitivity and a published response from 700 Hz to 18 kHz. It must be paired with a compatible horn and protected with a crossover frequency and slope appropriate to the system.
