As for the second bolded remark, so now we're not even talking about the HomePod anymore? Certainly not as it exists today, which is what this thread is about.
Surround Speakers
And lastly, the surround speakers. Per Dolby and DTS standards, your surround speakers should be 90-110 degrees off center, directly to the side or just a little but behind your seating position. Also, as opposed to our front speakers, the tweeter of the surround speakers should be 2-3 feet above ear-level when seated as this makes it them harder to localize. In other words, it makes it harder to hear exactly where the sound is coming from, which creates a more realistic surround field. This will likely necessitate wall mounting or using tall stands.
Keep laughing and insulting but you may want to try and disprove any one of my points. You don't want them firing directly into the listening position you you want them going above the listing position and listening to the de localized surround content which audyssey is already fully capable of calibrating. Again yes you are talking about a home pod again the only difference between a wall and a ceiling is the orientation of the speaker. What is difficult about changing the orientation of the speaker? It's a hell of a lot easier than drilling and wiring 5 holes in the ceiling would be.
