- The first measurement is a combined far and near field measurement. The impulse response shown is the far-field measurement.
- The second measurement is my best attempt at showing the off-axis response, measured far-field at very roughly 15 and 45 degrees.
- The last two measurements are near and far field distortion measurements.
