Description
The Beyma SPL70FE is a 1-inch-exit ferrite compression driver designed for high-output upper-midrange and high-frequency reproduction through a compatible horn or waveguide. Its lightweight edgewound aluminum ribbon voice coil, aluminum cover and PM4 polymer diaphragm are designed to provide strong projection with natural sound reproduction.
The 8-ohm driver provides 109 dB sensitivity and a published response from 700 Hz to 19 kHz. The current distributor table contains an ambiguous power entry, so a wattage is not stated here. Use Beyma's current SPL70FE technical sheet to establish the minimum crossover frequency, slope and amplifier limit.
