I know about the dentist chair scenario... experienced it with a Wilson Chronosonic/ D'Agostino / & room DSP'd.
At the listening spot everything was razor sharp at the exact dead center in the sweetest spot. After a while I wanted to relax, and slouched a little in the chair. That few inches drop in height was already enough to yank me out from the sweet 3D spot, even though I was still dead centered between 2 speakers. Also, move head 1 inch to either side, and the 3d and EQ balance just both collapsed in a major way. Those unfortunate suckers in the rest of the room suffered the same. (After a few minutes, I gave up my seat and joined the suffering team... after all, we are all suckers in audio ; )
Now, that was a super narrow and tight dentist chair! Long live DSP (preferably limited to the car industry and appliances...)Indeed, a big part of being an audiophile is to get together with your buddies and listen to the music together, and talk stories. With that type of scenario you get a bad feeling in the mouth, excluding everyone from the fun but one.My speakers are omni, I can enjoy an uplifting experience that fills the room at the sofa, the floor, in front of one speaker, anywhere.
I love to stretch out on the carpet, and watch a movie from there. From that vantage point the screen fills up the entire field of vision.. :) I have my "home theater" running from the 2 ch stereo. With the omni speakers it gives a much more coherent immersive experience than any gazillion speaker variant I heard.In general, when the speakers on axis and off axis response are super close, then the sweet spot will be wide. The bigger the on/off axis discrepancy, the narrower the sweet spot
