Unfortunately, I don't have pictures. I stuck a strip of industrial velcro to the sides of my PSR2100 and to the sides of each satelite speaker. If you want the speaker to face the audience, the speaker with the volume knob should be on your right.
I have used this duffle bag system at a couple of jobs today. I didn't even take the subwoofer out of the duffle bag, I just opened the front to expose the speaker. The duffel bag I purchased had another pocket on the other side which, after I cut the lining, I can open the zipper and take out the cables. I don't know how professional it looks to have a duffle bag sitting at the foot of the keyboard stand. I suppose most people wouldn't care.
If anyone wants, I can get the SKU# for that particular duffle bag.
The YST-MS50 delivers a lot more deep bass than my Motion Sound KP100S, but I don't think the sound is as balanced accross the EQ spectrum. There is something missing in the low midrange. With the satelites pointed towards me, the system sounds very pleasing, but with the satelites and the subwoofer facing the audience, the sound was rather muddy. With my KP100S setup, where the amp is besides me, the sound is excellent.
I'm going to play with this setup for several more gigs. If it doesn't cut my setup time as compared to the Motion Sound KP100S, I will keep on using the KP100S, and only take this system out if I have technical difficulties or if I need more volume than my KP100S can handle.
