Crescendo 10M

T
he Crescendo 10M is designed as a dedicated mid driver, providing high output, low distortion midrange from 250 Hz to 3.5 kHz. Built around a die cast chassis, the driver features a 2.5 inch voice coil driven by a 6.1 kg motor system. This yields an average sensitivity of 98.5 dB over the unit’s operating range, combined with an A.E.S.
power handling of 250 Watts. The heatsinking effect of the large magnet structure and die cast chassis yields low power compression, producing maximum output levels of up to 124 dB. The Crescendo 10M is best mounted in sealed enclosures of 5 to 10 litres.
