The Yorkville short speaker stand in the earlier photos was a bit wobbly. I just replaced it with an Audio 2000S stand which is far more solid. This stand is steel rather than aluminum and quite a bit thicker construction. This stand is rated for 100 pounds: twice the weight of the Roy. It has just one height setting but it is about right: as high as possible while still giving easy access to the top mixer controls. That height is secured with a pin instead of just knob tightened tension. The legs are orange so you don’t trip over them:
So what I’ve ended up with for a front facing slightly elevated Roy stand is the Audio 2000S heavy duty short speaker stand with the K&M 26747 Projector tray on top of it.
