why 3D Holographic sound

I have speakers tilted up about 2" and about 7 feet apart, and 3feet from back wall, my room is about 12x17' and carpet floors,using VR3s' speakers,kown to cast a preatty decent sound stage,just replace my VTL 5.5 for a joulet 150mk11, though was my preamp, was wrong,need to find a solution,when standing the sound and imaging is absolutly Gorgeous, will try difusing panels, next:

"I have speakers tilted up about 2""
There's your problem.

HI, thanks, Etran, will try leveling speakers, will get back to you with the results, thanks: and by the way,upgraded from VTL, to joulet 150mk11, ans boy what a diference; much more resolving, and organic sound, upgraded due to imaging problem, was a win,win, situation in my case:

I think Etran and Shadowshaman nailed it. Especially the 2" tilt. Take that away and your stage height will definitely drop down a bit. The best part is that it's FREE!

I had a similar problem with my VR4JRs and resolved with tweeter diffraction devices offered by DifFraction be Gone at:

The are essentially pressed wool felt pads that surround your tweeter drivers. I tried to make my own but could not find the correct material online or locally.
I am in no way connected to this company. I tried their money back offer and will not be sending them back because they really tightened-up image placement. It is a solution incorporated in many off-the-shelf products such as Dunlavy speakers and a few others.
