I have an S1 and have used it for a couple of small gigs; it's not the same as my Nano 600 or FBT Maxx40a's, but it's decent for smaller rooms / audiences.

A trick that I want to try, is to cut a length of tubing of the right diameter (speaker stand size) and stick it up in the hole (sorry for the graphic language here) since there is a pressure switch up in there (I can feel/hear this switch physically when I put fingers up there and press on it). Then, maybe, I can put the speaker in any orientation, and hopefully this pressure switch will cause the EQ-setting circuitry to ignore actual/physical orientation; the speaker will "think" that it's on a speaker stand (maybe).

This *may* set the EQ to be the "On A Stand" EQ, which will have more bass. I'm hoping that this is a way to bypass the "EQ-based-on-position" thing. I'll report back when I'm able to give this a try ...
