House, as I mentioned many people don't want to mount the speakers at ear level when seated, it just does not work out for everyone's situation. An example would be those that have a wall mounted plasma/lcd television.
In my upstairs living room, the bottom of our plasma is at about ear level when sitting on the couch. Unless I had small stands, there is no way my m22's tweeters could be at ear level. The tweeters are probably about a foot above that or in the 4'6" or so range and they sound fantastic.
So I guess what I'm saying is do what works for you, just don't get to crazy.
