1. Measurements are taken at 3m on-axis,
1
/3 octave, unless otherwise stated.
2. Response depends on loading conditions and room acoustics.
3. Measured with a single boundary, 1 m from rear of cabinet.
4. Phase variation from pure delay.
5. Measured at 1 m, with pink noise or music.
6. Nominal 8Ω resistive load, pink noise, 100v peak.
* Refer to UPA series Q+A for input module options.
