Room Treatments added, with negative effects..

Thanks folks for the comments so far. Some interesting possibilities. Just to mention, while I can put some absorbtion material on one of the side walls, it won't be symetrical with the listening position and the speakers (they will need to be closer to the listening position, as there is a corridor in that area of the side wall). Also, the other wall is all glass door, with curtains between. I could attach the material to the appropriate part of the curtains, but that seems like stretching things a little. I guess I could try the ceiling as well.

Overall, from what I've heard it really seems like the panels have only deadened the sound - I somehow have my doubts about any benefit they're going to offer. I'll try removing them from behind the speaker, and then maybe try the opposite as well. I'll also try removing them and adding more to certain areas. It still seems like a big confusing mystery though. I wonder would the addition of some highly reflective surfaces (rather than absorbant surfaces) made a positive difference. Cheers,

Well, folks I think I solved the complex room treatment challenges...... by removing the *$(%&#@ treatments altogether. From the effects I was getting, it's hard for me to see how these absorbtion treatments can have any benefit. I'd still be open to experimenting with tube traps and defraction type treatments (although those two seem like pricey experiments compared to the cheap foam), and I'm still of the opinion that room set (especially speaker placement) up can have a huge impact on sound quality. That said, I think I'm done with this foam stuff. Thanks to all for the suggestions though. Cheers,

Hi Folks:
Thanks again for all the additional suggestions. I have the Virgos set up based on Audio Physic recommendations, although not their ultimate preferred position (which is 50% the way into the room), but rather just 25% into the room from the back wall, and 25% away from the side wall (the room is not a dedicated listening room, so I need to compromise a little). I could experiment further with the toeing though. Seating position is almost against the back wall. I'll try the side wall absorbtion suggestion when I get a chance - will need to make the panels though, as there is no wall to attach them to in the appropriate area of the side wall (a corridor on one wall, and a wall of full length windows/ curtains on the other side wall). I guess the idea there would be to minimize side echo/distortions on the sound, allowing the ear to focus on the primary/first sound waves which come directly from the speaker?? Seems reasonable, if that's the logic. I can try and experiment with tube traps later, but my room characteristics make that difficult - the door opens on the far left of the room (preventing the addition of a tube trap there because it would be an obstruction in that corner). Other far corner is bookshelves on either side of the corner (probably good defraction anyway). Near left corner is desk/PC etc, and near right corner is bed. Hence, no good places for tube traps (in corners anyway). Center of ceiling is an overhead fan, so not good for any treatments there, but I guess I could put some before or behind the fan (would absorbtion be of any use there, or would it cause more problems?) Anyway, thanks again for all the great input. Getting the room right is challenging. To answer an earlier question - I don't feel I'm trying to solve any apparent problem with the sound. Rather I just want to get the most out of my room and improve the sound if possible. The sound is absolutely amazing from my perspective - I guess I'm always trying for better though, as I'm sure we all are.
Cheers.
