Calling all room treatment type specialists...

I bought one of those great Maxell Tape commercial posters...remember the guy sitting in his chair with the speakers seemingly blowing in his face.  Well, I don't want to put up a standard glass/plastic frame, because I think it would look a little cheesy in my room, AND b/c I don't want a hard reflective surface in the general area where the picture would. 

I would like to consider whether that poster can be adhered to a material that in turn is the top of a sound absorption panel.  I've been making my own absorbers for years with Roxul, wood framing, and the covering material of my choice (easily passes air through the fabric).  But what if I try to adhere that great poster to the face of the panel?  My limited understanding says it will reflect higher frequencies, and allow lower frequencies to pass through.  Perfect.

Any thoughts on whether the poster will be more reflective than absorptive? And what would you use to adhere the poster.  Spray on adhesive, maybe? 

Thanks.

So...Geoffkait...I have to admit I have no idea what you're talking about.  That doesn't mean much, b/c I barely understand much going on around me anyway.  Are you being funny, or is there something else to tuning a room than taming runaway frequencies, isolating our electronics from vibrations, and proper cord placement?  Is this all feng shui stuff? I'm generally familiar with the idea, but affecting sound quality???...that seems a stretch. But then, I would have thought fancy cables and isolation were voodoo until I experienced the effects myself. Always good to keep an open mind...at least for a while.

Sounds like the practical voices have it!  Just put up the damned poster and enjoy it!  Though geoffkait's diffuser idea has me thinking.  Too bad there's a big TV between my PSB Imagine T2s...I might have tried it just for kicks!

Thanks for the feedback.

I looked into the GIK Acoustic panel idea.  I might do it, but the problem at this point is that they need to start with a .tif or other digitized image.  I have the paper poster, but so far I have not found a digitized version of adequate resolution....just small images online.

So, I went the easy route.  After a quick study online, I headed down to my local art supply and bought a 3x5 foot panel of 1/2 inch black foam board ($12) and a can of spray adhesive (appropriate for photo paper $7).  Laid everything out on a flat area.  Rolled the poster up on a 2 inch round sleeve.  Sprayed the whole board and let it set for about a minute.  Started unrolling and used a plastic spreader knife (4 inches wide) and went to work unrolling and pushing out the bubbles.  I trimmed the excess board away and hung it on my wall with 2-sided tape.  Perfect!?  Well, not quite.  My wife was the first to notice that the direction of the apparent sound on the photo was opposite the sound coming from my speakers.  Could have put it on the opposite wall and fixed that, but a pesky thermostat complicated that idea.  Oh well.  But it looks great, and I'll get to enjoy it tonight when my buddy comes over for a listening session.  May have to turn it up a little extra loud tonight to get the full effect!

Thanks for all the input.
