Damn that Tyson. Always seems to know what he's talking about. I totally agree with the Tyson-meister. It seems with my M3's that once you obtain a certain distance from the front-wall and side walls, treatments seem to matter less and less. In my case, the speaks are about 51" from the front wall and 39" from the side walls. As I've written previously, I have that hideous flat screen between the speaks at 40"-65" high. I know..... Anyway, I think Tyson's advice is sound - settle in for a bit and listen to how the system presents. You may find, like me, that treatment is, well, not sufficiently impactful to justify the expense/effort. Enjoy.
