Considering setup. I'll have to play around - will be outside in backyard. Considering throwing a moving quilt on the lawn and laying cabinets on their backs, measuring from above. Should be fun, neighbors outta love it.
Thirty five years ago, that's how Community measured their horns and loudspeakers. The had the measurement mic on a 'fish pole' attached to a TV antenna rotater, all mounted to a 20 ft tower, IIRC. They gathered the data on a 1/3 octave RTA and took photos of each step. The data was manually plotted from the screen shots.
