Speaker Height?

most speakers will follow the mid, tweeter at or near ear level, I like a woofer up top for a bigger and fuller sound, having had dynamic speakers, the Electrostats and now a high and low placed woofer with tweeters in the middle (my speakers happen to have a full length mid ribbon)...all the same I like what the woofer on top and bottom do for the sound.

As usual, there's no simple answer. From my listening experience, I'd say there is SOME correlation between soundstage size and the size of the speaker. However, the talents of the designer(s) and the design goals can confound your expectations in some cases. A speaker's dispersion characteristics and your seating distance from the speakers also influence how you perceive sound. Dipolar speakers tend to sound bigger than their physical size might lead you to expect.

Tweeters should be as close to ear level as possible. Period. It's simple physics. The shorter the wavelength, the more directional it is. Unless it's an omnipolar design, the high frequencies from the tweeter as so directional that moving even a little bit will alter the sound. It is because of the tweeters that you can get such a dramatic difference in soundstaging, imaging, etc. by moving speakers even a few inches.

Sure does... too low and you risk to knock over the beer can or wine glass... an essential part of the experience.
