Listening Height Adjustment -- Is This Why Two People Don't Hear the Same?


Just wanted to pass on a recent experience, and surprise, in my system

My room (https://systems.audiogon.com/systems/5707) is set up for one person to listen. I have a medium height arm chair at the listening position and had always assumed that it left me with my ears broadly in line with the tweeters in my Magicos (i.e. 42-43" off the ground)

Well I checked and I was actually at 38-40" depending on how upright I sit. Wondering how much of a difference getting it just so would make I purchased a set of add on feet, each 3.5-4" tall and added them to my chair -- not a good look!

But wow, what an improvement in sound. Tonally the speakers take on a very different balance, upper mid range and vocal intelligibility is substantially improved, bass is lighter but better defined and overall integration across the frequency range is much much better than before

The odd thing is that I don’t have the tweeters pointed directly at me -- they’re angled about 2’ off to either side, so what would a couple of inches in the vertical make such a difference assuming the tweeter drop off is uniform in all directions? Is it more a matter of driver integration?

This experience leads me to wonder
a) how many of us have actually measured and adjusted our set height to optimal/tweeter level, and do we do this every time we audition a new speaker, and
b) if two individuals are not the same height do we adjust for the difference in height between them sitting -- say a 5’6 vs 6’ person that’s probably a 3" difference sitting -- unless your chair has adjustable feet the experience of the two individuals may be completely different

This is a major issue for me.  I dislike speakers where the sound is not as pleasing to listeners who are not in the sweet spot.  I've owned speakers which drop off sonically when standing (worst-Acoustat X, the coffin speaker).  My current speakers (Legacy Focus and Signature IIIs) have a small loss of highs when standing but appear to maintain their sound from 2' to 5' high in the vertical realm.  Guests and my wife say they enjoy the sound across a 10' wide span couch as well.  There are many speakers very highly regarded that have a limited height and width seating/listening area.  I would rather own my less than SOTA speakers than those SOTA limited height and or width listening area speakers.
I agree that tall stats allow for a large range of listening height as I previously owned Acoustat 2&2s and Martin Logan Monolith IIIs. One loses some of the highs from my Legacy Focus when standing but the overall sound is less directional than when sitting.

My speakers are 10’ apart speaker to speaker center, towed in about 10 degrees and my listening area is 12’6" from between the speakers. 20 years ago I tried moving the speakers closer but it resulted in too much bass even in my big room. I can’t move them any further apart due to my CD drawer cabinet has to open to the outside of the left speaker. I don’t think I would want the speakers to be further apart.

In my second listening room, my Legacy Signature IIIs are only 6’ apart, not angled, in a room measuring 13’ wide X 20’ deep (and open to one side and the rear). It has great focus and wide, even dispersion without any room acoustic treatments. The room also has a vaulted ceiling from 8’ at the speakers to 10’ at the rear, like a horn. Tremendous sound with little effort compared to my main room which is too live and had slap echo without room treatments. This is Oregonpapa’s speakers in a better room.
