Speaker Axis ?

Sounds similar to my former situation. Can you tilt the axis of your speaker back? That should tell you if this exercise is worth pursuing.

Also: How tall are you? How high is your seat off floor? How far back from front plane of speakers do you sit?

If you haven't purchased furniture recently, get ready for some serious sticker shock.

Just slouch down in the chair and listen.

It is easier and cheaper to raise the speaker than the furniture, unless you use a barber chair for a listening seat.

I tend to prefer the tweeter to actually be just slightly higher than ear level on conventional speaker designs.

surely nobody has to tell you to listen for yourself and see?

I have always used the rule of same tweeter height as ear height in listening chair..So 41" and 41" for me.....I would assume that each speaker is different depending on the Dispersion of the tweeters but I always try to keep them close in height...I am no expert,for sure....
