Chris that shot is a little better I must admit. It shows a bit more. I agree with Chuck in that pulling the Yamahas down to where the Auratones are is a good idea. Leaving them on their side might also be slightly better in this case. Standing them up might put the tweeters a little higher.
Putting the Auratones close togther and in the middle is also a good idea as well. It puts them more directly in front and removes a bit of the stereo field too. That wont hurt in my opinion.
Personally I would not bother with the JBL's at all. They look to me to be just cluttering up the situation. I would set them up over the other side of the room somewhere and use them as Hi Fi speakers and for quick alternate mix checks, but that is just me I guess. I would put their grills back on too.
Here is how the good guys are using one Auratone!
(ignore the Lexicon Remote control and look just above) Another good thing about having your monitors closer together is that the triangle gets smaller and better. Less problems with the room. More speaker action. Not sure I have them as close as they are in this pic but similar.
There is a way for setting up how far apart your monitors should be as well.
A good thing to do is to set your speakers up on a long plank for the correct orientation.
(In your case Chris you dont have to because you have the top shelf of your table setup. But you need to remove the computer monitors for this test though) You need two friends to do this. Feed a
mono signal to both speakers
(music pref something very nicely mixed eg Steely Dan) Start with them reasonably close togther eg 3 feet and centered in front of you. You close your eyes and listen for the phantom image in the centre. The two friends gently slide your monitors apart while you listen with your eyes closed. At some point the centre image will break up and fade away. That is the point when they are too far apart. The idea is to slide them back again so the phantom image re appears strongly. And maybe touch more in for extra measure. I have done this and this all happens at 1.1 meters for me and my room.
They can be too close together too and you get a bulging of the centre image ie it becomes too loud and you start holding centered pan things down only to find they are not loud enough on other systems.
You should do this test first and then see if two computer screens will fit in between. They may not. If they don't and you have to widen the monitors to fit them in then this is a compromise. You have weakened your centre image. Everything sounds better and more robust when the monitors are the right distance apart. This should be more important than anything else. I have got three screens actually but only one in betwen the speakears. The other two are on the right of the right speaker and it all works well.
Mastering houses never have two screens and the only one is usually pushed further back to stop reflections.
(for mastering your centre screen really should be on a movable reticulation arm so it can be pushed well back behind the line of the speakers. Things can sound different when you do this) My son has given me a 27" monitor recently and I really like it. It handles all the stuff I need to see.
(Use screensets more!) Use your ears more and your eyes less. (Like the old days, no screens at all!)
