Man, I don't know how I missed this setup over the years, absolutely incredible Boonyarat, room and equipment. It was nice reading the entire thread, Boonyarat, you should move your most recent photos to the first post
Now that the Maxx's have been added to the system, the one item that stands out to me for which one of these is not like the others
I think is the center, even more than the subs as you have all ready upgraded to the 212's. I would say a Polaris is in order don't you, or at the very least the Mezzo? After that then add the Thor's Hammer (or two of them) like all ready mentioned. If your room was a bit wider and deeper you could have kept your W/P speakers and used them for either side or rear surrounds.
