Is soundstage DEPTH a myth?

@toddalin  

 How did you get stereo in the recording? The mic. in the picture looks mono. It’s interesting to hear the original track over headphones and then compare it to you recording, which sounds more reverberant and brighter.

The Behringer mic used to display the spectrum is mono. You cannot "analyze" mono pink noise through both speakers simultaneously because of constructive and destructive interference in the room. I've shown only the left speaker, but the right is similar.  The audio recording was made with a Nikon D750 DSLR camera.

Yes the recording is more reverbrant because it picks up the untreated, big, room acoustics. The brightness is my preference (but also the room) and could be turned down at the L-pads or flattened to a more conventional curve with the switch on the crossover.

Thanks for clarifying the use of the Nikon camera’s microphone. You had mentioned that but I didn’t make the connection to it also being the audio source. Is it the camera’s built-in mic. or a separate mic. you attached? I can hear the stereo separation.

I own that same Behringer DEQ2496 and it's calibrated microphone. It's been a useful tool over the last 15 years or so that I've owned it. Yes, you can't calibrate the tweeters at the same time unless you can somehow get the distance to each tweeter exact within about 1/8". That should get you up to about 10,000 Hz. Of course our ears are separated on our head so our ears really don't like two tweeters playing into both of them at the same time either. At least my ears don't care for it. 

When I finally bought a nice Dac and streamer for my smaller system for the 1st time I heard the imaging/Soundstage. I thought it was just a myth too as this was my 4th system and my cheapest one. Streamer to Dac to SS integrated to bookshelves. So when I heard it I began to question why my large living room sytem with expensive gear wasn’t similar if not better. Expensive tower speakers and hand built highly detailed low distortion(likeSS low) tube amp with a pretty high end turntable. So I began trouble shooting w speaker positioning, changing my interconnect xlr and rca connections. I finally nailed it when I changed my modern tubes to NOS Ken Rads. So now massive, massive soundstage far beyond the side walls of my living room and 3d imaging. So yeah two diff systems two different solutions. Or maybe neither system was ever set up properly or some aspects of equipment wasnt allowing me to get everything out of my system until I addressed them. Whatever the reason I would not stop tweeking things until you've arrived. You’ll know it immediately when it happens even if you’ve never heard it before(as in my case). Best of luck enjoy your journey.

Buil in mic..., so of course separation suffers. But the Nikon actually does a pretty good job, and lots better than many cell phone recordings I’ve heard.
