First, we measured impedance and found Zmin to be 2.8Ω. So 16.7v is required for 100 watts, 23.7v for 200 watts, 33.5v for 400 watts, 47.3v for 800 watts and 66.9v for 1600 watts.

Next, we measured output at 28.3v. Since we measured 10 meters away, the values correspond to 2.83v/1M.
The blue line is SPL, and the violet line shows distortion. Since measurement was taken at 10 meters, add 20dB to find SPL at 1 meter. With 100 watts input, the 10 meter measurement works out the same as 1 watt input measured at a distance of 1 meter.

From this, we perform an inverse FFT to obtain impulse and step response:

π response at 10 meters with 16.7v (100w) input (1W/1M)
Measurement at 200 watts:

π response at 10 meters with 23.7v (200w) input
Measurement at 400 watts:
12
π response at 10 meters with 33.5v (400w) input
Measurement at 800 watts:
12
π response at 10 meters with 47.3v (800w) input
Measurement at 1600 watts:
12
π response at 10 meters with 66.9v (1600w) input
