center speaker height with two rows?

I think a lot of people like it at the center of the screen.

I wouldn't call it thinking too much, but not thinking about it from the right angle. Can you really tell a 6" difference in height of a sound at 10-15 feet? Your ears are better than mine.

I'm probably going to split the difference and make my speakers (left/right/center) at half-way between front/back row. Since my front row eyes will be about 1/3 of the way up the screen, that puts my speakers about mid screen.

Probably also good to have the tweeters of all three front speakers at the same level.

My tweeters are all at the center of the screen, angled down slightly to ear level of the first (only) row.

your ears are much more sensitive than that. have someone tilt your speaker less than half an inch. if you can't hear the difference then start learning american sign language because you are on your way to total hearing loss.

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

What I did was put a laser on the top of my speaker and then angled it back until the laser hit the spot on the seats where the ears would be. From there, I was able to calculate the angle. I think 15 degrees is what I ended up doing. That seemed to intersect the spot on both rows 1 and 2.
