Speakers are about 11' apart, with a listening/mic location about 12' from the plane of the speakers.
This is most definitely an in-room response sort of scenario as opposed to quasi-anechoic (i.e. not close microphone).
Guess How Big My Speakers Are
If you read any of my threads on here or looked at my virtual system you probably already know the answer to this question, but for those who have not, try this as a thought exercise. Given this plot alone how big a speaker do you think this is?
Hints:
I’ll reveal my answer if we get 5 guesses or more. :)
