well, other than height Actually, I'll be using a 2" dome mid and have been using that as listening height for the crossover calculations.
I guess I meant things like, how large should the top plate be in proportion to the speaker, construction, "features", etc.
Since you mentioned it though, what's a good "average ear height"? I think there was some number in a Vandersteen setup guide I used to have, but I no longer have it. I was assuming 38"-42".. 2" dome mid is 8.5" up the baffle, so 25" Dynaudio Stand1 probably is too low ...
