Sudden realization on Soundstage and T/A

So perfect centered sound stage is quite literally different for everyone because everyone's hearing levels are different and some have loss of hearing on one side or the other to some extent there for I had 4 people in my car, one said the stage was centered, one said it was to the left and one said its all the way to the right and one said its slightly to the right.

How this impacts me car audio wise now is When i help people tune in person, I cant just time align to where i hear its centered, I have to have the person sitting in the driver seat and have them visually hear where its centered according to them now along with left right mid/tweeter level balance.

I dont know why this literally never crossed my mind until recently.

 
Differences in anatomy is why sound recreation is opinion based. Some things can sound wildly different to people with an assorted amount of congenial and physical defects.

 
You said it, man. Everyone is so different with their physical builds (height, ear canals, haircuts, etc...), perceptions, limitations, natural inclinations, and preferences... It's impossible to please everyone at once. This is also why people should be more forgiving of how someone else's system sounds because it's rare that two people will like everything balanced or biased in the same way. I actually like hearing the way other folks have tuned their vehicles so I can pick up on those differences and engage them in discussion. Sometimes I teach, sometimes I learn. It's the way it should be.

Everyone is right if they like the final product.

 
With a demo from someone I know who has a fairly loud frontstage, and thankfully he's into SQ, he was messing with the right side and left side and asked which sounded best. I have a little hearing loss in my ear so it was a little difficult to determine which sounded best to me. He got asked to judge other systems during comp times but sounds like he's gonna pass it up. Need someone with good hearing and no ear infections for something like this to have that perfect centered SQ stage.

 
a buddy of mine had tubes in his ears that were removed later in life that left scar tissue. He had his eq set to boost the shrill range of the mid/highs to the moon it was physically discomforting to listen to his stereo at a loud volume to me but he said it sounded normal to him. My dad cant hear high pitched beeps or ringtones so i just imagine his hearing is like trying to listen to stuff with your head underwater.

 
I've been into home and car stereos and EDM for 20 years. One thing that always annoyed that crap out of me is when your listening to drum and bass or any fast bass based music and the bass is always a split second behind the rest of the song. With my kenwood ddx6702s it dawned on me to adjust the time alignment for one of the listening presets. Instead of measuring the 3.8ft from speaker to center. I moved each speaker back 19.62 feet. Now no mater what song I play, the attack and decay of the bass matches upexactly with the rest of the song.

That’s mostly phase.

 
It’s on Spotify.
my stage is dead center on all the reference and tracks to me at least. But yeah, some people have significantly less hearing on one ear due to sh*t happening in their lives. Found out one of the guy was in a live band most of the times without earphones and the speaker was always on left so his left ear barely hears anything.

Check each speaker for shorts. A pinched wire grounding out or a individual blown speaker can sometimes make the internal amp go into protection.
