Please review my first REW subwoofer reading

[Daxaudio]

Hello,

This is my first time using the program, I followed the instructions and want to measure my subwoofer. Here are the results, what do you think?

Looks like the measurement has worked properly, but best attaching an mdat file.

Thanks, here is the proper format.

Best measuring the channels individually, not L+R. There's quite an increase in 2nd harmonic distortion above 1 kHz in the full range measurement.
