You are rigyht, tilt is different. I was just talking about speaker height. If you tilt a speaker left or right, up or down, relative to the listener, you are potentially in a different part of the 'lobe' of the speaker. You could hear a frequency delta.
I'm talking about speaker height, with the 'tilt' being constant. If you go higher, it tilts more towards you so it's still pointing the same place relative to the listener. In that case, I think a few inches might be tough to detect. Granted, I have not done any double blind testing or anything.
You do raise a valid point, however. Assuming you place the speakers (tweeters) at a height to split the difference between the front/back row ear height, where do you point the speakers? Also straight forwards, or angled down slightly to point at the prime listening spot.
Too many variables. I think I'll just go buy some Bose
