You have a beautiful system. I love the look of those tylers. For a different take on the problem, I would suggest looking into getting a front projector for your room and have nothing in bewteen your mains. You mount a screen on the front wall and go from your 50" diagonal image to a 90" or 100" widescreen image instead. It is alot more fun and immersive with a big image and is also nice to retract the screen and it all goes away. It does not have to cost alot either and can be done quite well on less than $1500 bucks. It has worked quite nicely for me in my room.
