Organgrinder,
I did buy the S1 Pro - kept it only one day and did not look into the various adjustments available on it. Nor did I adjust any of the settings on it as it came out of the box. Since then I have heard the SD1 Pro being used in some rather large rooms and it sounded great.
That made me start rethinking my first experience and give it a try again - this time using any and all of the various adjustments built in to the S1Pro.
