Summary
HTM-200 SE MEASUREMENTS...   
*All of the measurements you see below are unsmoothed and use a 5dB/division scale where appropriate. It is common for loudspeaker manufacturers to publish measurements that have been smoothed to 1/3 octave (meaning 3 graph points per each octave) and use a 10dB/division scale. This has a tendency to make the graphs look smoother than they are.

We have chosen to be different.
