Notes:
* The power capaticty 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 1m distance, on axis, with 1W input, averaged in the range
1 - 7 kHz.
[Hz]
Note: On axis frequency response measured coupled
to TD-385 horn in anechoic chamber, 1W / 1m
