Absorption or diffusion????

Hi all, I've been adding some acoustical treatment to my room the last couple of weeks. I am waiting for some of the Auralex Tfusors and Metrofusors which are on order from my local Sam Ash. I have implemented pieces of their Studiofoam 2" pyramids, wedgies and Lenrd Bass traps for absorption. I am thinking of applying some of these on a piece of cardboard and mounting it to the screen of my 50" RPTV via Velcro strips when listening to music. Which should I use over the TV, absorption or diffusion? The TV sits in between my main speakers.
Thanks
Greg

I have the same problem in my family room, i.e. a 55" rptv sitting between the speakers. For a cheap fix, I use two 2' x 4' panels of 3" pyramid foam, mounted to 1/2" pvc tubing. I guess you would consider this more of a diffuser than anything else.

It may not be ideal, but it was cheap, and it works. Solidified my center image, and allowed to the soundstage to deepen.

I think either would do the trick. But absorbtion is much easier and cheaper.

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!
