BassMaxx X2C Deuce basshorn sub
First, we measured impedance and found Zmin to be 3.35Ω. So 18.3v is required for 100 watts, 25.9v for 200 watts, 36.6v for 400 watts, 51.8v for 800 watts and 73.2v 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:
BassMaxx Impulse Response
BassMaxx Step Response
Measurement at 100 watts:
BassMaxx response at 10 meters with 18.3v (100w) input (1W/1M)
Measurement at 200 watts:
BassMaxx response at 10 meters with 25.9v (200w) input
Measurement at 400 watts:
BassMaxx response at 10 meters with 36.6v (400w) input
Measurement at 800 watts:
BassMaxx response at 10 meters with 51.8v (800w) input
Measurement at 1600 watts:
BassMaxx response at 10 meters with 73.2v (1600w) input
