Hi Don,

I've been using Yamaha YST MS50 speakers for some time now. George Kaye put me on to them to use with the 9000PRO. Since then I've used them on the 2000 and am now using them with my Tyros. They put out amazing sound and are easy to carry. I put them in a nylon bag with all the cable hooked up. When I get to my gig I roll down the front of the bag, hook up the cables, and am good to go. If you'd like picture of the setup email me and it will be on it's way. I'm guessing the MF speakers are much the same as the MS model.
