Measuring Room & Reference Monitor Speaker Acoustics

[EEVblog]

Measuring the speaker and room acoustics of Dave's Rokit 6 reference studio monitors.
Signal level microphone calibration, getting frequency response and waterfall plots to show the acoustic decay , and the difference with acoustic panels.

NOTE: The difference in the "clean" first response and the "messy" subsequent responses is that the first one was left speaker only, and all further ones were with both speakers, so you expect a difference response.
