Absorption or diffusion????

i don't see how you can possibly get the right answer without posting your room dimensions.

Why diffuse furniture that is harming the room? absorb it baby!

I'm with Rd, "I've always heard absorb in front of you, diffuse behind you." Anything coming off the TV would probably be a bad sound, distortion. Best of luck Gsselling, acoustic treatment is always so site specific. Cheers!

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.

A quote from a smarter guy then me

"For someone with a very small budget, making the rear wall of a room totally dead may be the only solution. At least that gets rid of flutter echoes between the front and rear wall, though at the expense of sounding stuffy and unnatural. But it's better than the hollow boxy sound you get from a plain flat reflective surface. Another option is to make the rear wall of a room partially reflective and partially absorbent. You can do this by making the wall totally dead, and then covering it with thin vertical strips of wood to reflect some of the sound back into the room. If you vary the spacing from strip to strip a little, you'll reduce the coherence of the reflections a little which further improves the sound." - Ethan Winer

Either Absorption or Difussion should work. But I like Shiva's idea the best.
