| Notes |
|
1. Measurements are taken at 3
meters on-axis, 1/3 octave, unless otherwise stated.
2. Response depends on loading
conditions and room acoustics.
3. Measured at 1.5 meters with
the DF-4 on a single boundary.
4. Phase variation from pure delay.
5. Measured at 1 meter, with pink
noise or music.
