Sound is better when I stand up?


Why is this? No matter my listening room (large basement with 7 1/2 foot ceilings or small office with 8’ ceilings), the sound is more open and more spacious when I stand up from my listening chair. When I sit, the sound compresses a bit. Sitting, the tweeters are about 5-6" above my ear level. Should I angle the speakers down?

My chair is at the apex of the .83 ratio Jim Smith suggests for getting better sound. I'm about 3' from the back wall and my standmount speakers are 3' from the front wall. 

What acoustics are responsible for this?

It's the wingback!

move a short back chair in same position, see what difference!

holmz no headrest, but it is a wingback. I wonder if that’s an issue

@simao
What is a wingback?
Is there a image of the model of chair?
(If there is some place for sound to bounce off of it can cause a problem.)

Have you tried a simpler chair, like a dining room chain, in the listening position?

Try standing up and moving rearwards so that your back is against the back wall… Does it also sound similar to the sound in the chair?

@simao 

I know what it’s like to work with a small room- you can see mine under user/systems. The tweeters in my speakers are above my head while sitting and it’s no problem. The image is centered and at a nice height. At first I would say to move a few inches further back but it sounds as though you’re very close to the wall already. Needs further examination 

@paradisecom Reference 3a MM Gen 2. I've had iterations of reference 3as for many years. They are in phase and the tweeters are on the outside.

 

@designsfx The speakers are 8.3 ft apart and my listening spot is 10 ft from both woofers.

 

I do appreciate everyone trying to help. This is more out of idle curiosity than any burning desire to rectify the situation. It could be that when I stand up I'm also getting the reflections from the back wall, whereas when I'm sitting down, those reflections are absorbed by the chair. It is a small room after all.

It could be a phase issue between the drivers creating the issue. What speakers are they?

@simao 

Help me out here- you mention a .83 ratio. How much separation is there between your speakers (driver center to center) and how far back are you sitting from the face of the drivers?

It would help to measure your room. Look into Room EQ wizard and get a mic. seriously.

Yes try angling them down ideally your ears should be level with the tweeters.

you need the speakers custom tuned so that they sound brilliant when youre sitting down rather than standing up. Nothing to do with acoustics. Its the speaker crossovers need retuning
