I could move the sides up a little or try and angle them more towards the front. The rears are about 3ft tweeter to tweeter and I think they are less of an issue. One of those other surrounds mentioned though may be the best option for my room.
It's easy to understand that since they're already up, one might not be bothered with new speaker locations. I mean, I haven't relocated my rears yet either, even if I feel they need to be further out. They have about double the distance between tweeters compared to yours, and are considerably closer to viewers. I still think they are too close to each other though.
Again, it's hard for me to discern the angles, but it appears to me that your present side surround placements would be ideal for a 5.1 setup, not 7.1. Those types of angles are meant so that the two surround speakers attempt to straddle the side and rear areas, but at the compromise of a larger gap between your mains and either side surround.
IMO, 90 degrees is truly ideal with a 7.1 rig, with the sides. I mean, at least for someone who is always using the rears too via matrixing (I've run into a very few who listen to 5.1 only as 5.1, and 7.1 only when the track is natively so). But who knows, maybe you'd hate my suggestion.
May I ask where you got that portrait of Eastwood?
