Speaker height...should known better

I appreciate all the responses. I am going to try an elevate the speakers a few inches higher by probably getting newer stands since changing chair height is irrelevant right now.

@bimmerlover I think these have a good vertical dispersion to a point they are sensitive to slight height difference. The problem I notice as I mention earlier is that high frequency drivers were below my ear level but visual perceptionfrom the listening position was not like that.

@erik_squires I feel I have that perception with my speakers. 

Remeber that you can just tilt them.  I've had good luck using relatively inexpensive wooden stands from Butcher Block acoustics with adjustable feet. 

Interesting how different standmounts can be designed for different heights. I have Marten Parker Duos and their stands are 30" from the floor to the base of the speaker. My ears are level with the lower part of the bottom speaker, not the tweeter, and it sounds awesome, with a very tall, deep soundstage. I've tried sitting on padding to bring my ears up to tweeter level and that did not sound right at all.... I realize this is very unusual design, but it works! Their other standmounts, the Oscar Duos are more traditional ear/tweeter setup. 

I know this isn't possible for some speakers, but I found that laying mine horizontally instead of vertically resolved that issue for me. That way all drivers are on the same plane, and with the tweeters on the outside, the soundstage widens considerably. I tried many combinations of height, toe in, and spacing with a vertical orientation but found horizontal at about 38 inches above the floor is best in my room. 

Easy thing to miss… and more important near field.
