Notes to Specifications
1. Continuos pink noise power ratings are derived from suggested AES standards sending a pink noise
signal having a 6 dB crest factor with a high pass filter set at the specified lower limiting frequency for
two hours. Continuos program power is a conservative power rating for reproduction of typical audio
program material.
2. Sensitivity measurement is based on pink noise signal with input power of 1 watt and measured at 1
meter from the mouth of a horn with a Q of 15 on axis and averaged between 2 and 5 kHz.
3. Frequency range is defined as the measured frequency response -10dB relative to the rated sensitivity.
Applications
Compact 2-way systems, multiple-way medium throw
systems, compact and medium size high quality line
arrays. Unique driver in the market offering high power
handling in 70 mm diameter. Very good linearity in
combination with RCF HF94, HF64, HF101 horns.
