I'm not disagreeing with what you are saying, just modifying it a bit. As I illustrated in Post 18, if your ears are within 1 foot (horizontally or vertically) of the tweeter, there is pretty much no change. Though that is a based on an estimated 10 foot listening distance.
Tweeters at ear level is not always the best solution, though, in general your point is right. If we change the context to Toe-In, you can tune your speakers by using varying degrees of Toe-In. For brighter speakers, perhaps facing straight forward is better, for softer less bright speakers, perhaps pointing straight at you is better.
The same can result from the tweeters being higher or lower.
Could the Original Poster tell us SPECIFICALLY what is floorstanding speakers are (brand and model)
or could he give us the measurement from the floor to the center of the tweeter so we have some context to respond in?
Again, I'm not saying you are wrong; I'm just saying that there is a ±
factor in the Tweeter Head High guideline.
