Hey, I was wondering if anyone had any suggestions for my current predicament. As some of you may know, I use my M2i's as my computer speakers, and they are on the same desk as my monitor, keyboard, mouse, etc. I notice that when I slouch a tiny bit to get my ears more in line with the tweeter's height, the imaging becomes noticeably better (as would be expected).

My Predicament:
Due to application (as computer speakers), I cannot use true stands with them as my desk is too long and the sweet spot would be far behind the listening position. If I were to aggressively toe-in to compensate, the sweet spot would be way too focused to be practical (any accidental lateral movement would ruin the acoustic image).

Now on to what I would like to do:
I would like to get some 3" to 5" stands. I'm thinking some kind of concrete block, but I have NO idea where to get such a thing. I have can grab some loose red-bricks, if you guys think that would do well.

Thanks for the help,
-Will
