I posted in the Genos PSR forum about this; I bought one Bose S1. It has surprisingly good sound, IMHO, for its size. Way better than a battery-powered Behringer I had been using (BT40 Pro or something like that). I tried it in 3 of the "orientations" and I could hear changes in the EQ. First I just it on the floor then a table, sounded best - full amount of bass etc. Tilted it back, aiming it "up", it had slightly less bass but still sounded very good. When I put it in "Floor monitor/wegde" position, I think they increase the "mids" a bit too much for my taste, got a bit "screechy", at least on a couple of tracks I listened to. Didn't have the feeling of mids being too high or screechy in the other positions; it sounded great in those positions. Maybe in floor monitor mode they increase the mids to help with vocal monitoring?
I'm hoping it will be good for me for things like practices, jam sessions / parties, small gigs ...
