@jcoehler , That got my attention as well as 28" is quite high for a speaker of that size to rest at. My ears reside around 37". A halfway point of 11.25" from the base is where the center of the tweeter is so, theoretically I'd need a stand around the 25-26" height.
If the off axis reach of the tweeter is good, I would think 22-24" would suffice and maybe even 20", if you slouch a bit.
All the best,
Nonoise
