Magnet:
neodymium.
This 1” compression driver features a lightweight mylar diaphragm that provides an excellent high frequency response with low harmonic
distortion. Other key features of this model are its excellent sensitivity (108 dB) and its low weight, due to the use of a neodymium magnet.
By the other hand, the coil-diaphragm assembly is easily field replaceable without soldering

FREQUENCY RESPONSE AND DISTORTION CURVES
Notes:
*The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer’s ability to handle normal music program material.
**Sensitivity was measured at 1 m distance, on axis, with 1 w input, averaged in the range 1-7 kHz.
