Notes on measurement conditions:
1
Measured on-axis at 2m in an anechoic environment and referenced to 1m.
2
Measured in half space at 2m with 4W sine wave input and referenced to 1m.
3
Nominal dispersion, measured in an anechoic environment and averaged over stated bandwidth
4
Calculated and verified by subjective listening test of familiar program material.
