Tweeter placement

i agree with uber. Ear level with direct exposure may or may not be best. It all depends. Set it up whatever way sounds best. Forget about any audiophile dogma. The best tweak is usually the ones that are homegrown. It's the great equalizer and helps keep one of the audiophile merry go round. Think out of the box as needed and live happily ever after.

One rule to obey is to avoid early reflections that smear the sound. Too close to walls floor ceiling is all not good. Most tweets are all directional to some degree. So it's the reflections from room boundaries in the path of the sound wave that matters most. Ear level is just one option that delivers the most high frequencies to your ears which may or may not be a good thing. It all depends.
