Well, duh. You wouldn't imply in-ceiling speakers to potentially be as good as a pair of "ear height bookshelves" simply because you are directly underneath them, on axis?
Ear level is misleading and a misnomer, really. The only reason people suggest ear level for front speakers is because they are normally direct firing, and the drivers will be on-axis for your ears if the tweeters are at ear level. (High frequency sounds suffer most when you get off axis.)
Often when one uses the "misnomer" of ear level, the tweeter is what is often implied. I would hope anyways that nobody mistakes that to be for the bass driver in a three way tower.
You can mount surrounds at ANY level and still be on-axis if you aim them. Aim them in a way that's consistent with the speaker design.
Of course. Duh. You can do the same with in-ceilings too.
Further, given the type of stuff playing through surrounds, plus the use of high-dispersion designs for surrounds - there's quite a lot of flexibility.
IMO there are two reasons to mount surrounds above ear level ...
- It's the only way you have a chance of more or less equal volume from each ... when they are to the sides one will be much closer than the other for almost everyone, and be distractingly louder. Mounted above you the distances are less different. It's a geometry thing.
This could be true. But, just because something or other is not always easy to implement does not all of a sudden make a statement untrue, does it? In any case I wasn't here to argue the merits of easy implementation. After all, a lot of seat backs are too tall. Do you miss the part where I said, "I guess in such a case where the surround is above ear level, one could hopefully angle them"?
- If there's someone sitting next to you they will block the sound from that side. If the speakers are above, you can all hear.
Yes, this would be the case if your side surrounds were at a 90 degree angle, or at least very close to that. Even at 110 degrees, with say 5ft distance to speaker, the heads shouldn't be blocking, if they are sitting somewhat close together. Sure, maybe some reflections/diffractions off the noggin, but whatev's. No issue for rear speakers, or LCR.
Unless there's only 1 person listening and you can sit exactly in the middle. Which, by the way, is what you have in a production studio, which is what the link in that other thread is about ... not at all relevant to home theater.
Put them above ear level, well above ear level if need be, and aim them at the seating.
I agree that it's best to aim them, and I never once said otherwise.
