Well it helps that I enjoy hearing myself! Actually my situation is different from many because I play instrumental music only, and my audiences usually expect me to play at a level that is comfortable for them to be able to talk to each other over. Even when they pick up and get to dancing, I really don't play as loud as others acts typically (but I can). Also, since I don't sing then feedback isn't a problem. And finally where and how I use the KP-200s is actually how it is recommended to be used by the manufacturer. So using the KP-200s behind me works out great for me but your mileage may vary.

In some cases I use my pair of JBL EONs G2 10" when space is tight but the speaker placement is still the same: behind me and pointing towards my ears. In large outdoor gigs I use the 10's sitting on their matching subs for the front speakers and the KP-200s behind me as a monitor. I avoid speaker stands indoors - I believe they tend to point the sound into the audiences face, whereas I prefer a more ambient approach and like the speakers to point more towards the ceiling and the sound bounce down when possible.

I have EQ settings programmed into my 9000 Pro for either the JBL or the Motion Sound speaker setups. I then tweak slightly to accomodate the room.
