I ve already tested it twice on my outdoor concerts during September 2019. I have my own project - one man band (looper with guitar, voice, trumpet, and percussions) Stagepas 1k has been great for purposes of my set up so far. Its very practical gear (I like its just one piece when dismatled) it gives me much better sound. Voice gets very clean, bass is fairly deep. It covers outdoor space very nicely. Will test for indoor next week.
