I definitely am not looking to just scrape the barrel. In the grand scheme of things, a few hundred bucks on 4 bookshelves on the ceiling is not a lot of cash for this. Mainly I was just curious if it actually mattered or if it was just spending for the the "what ifs" and all that. I'm not sure what info really comes across atmos and if it matters. There's so much contrived contradicting material out there that's pretty much all anecdotal and I'm not interested in some goldenear style review. I definitely like a meat & potatoes review with honest numbers or at least as close as it can be to that, with some preference stirred in as a lot of this is entirely preference anyways.
So I'll axe the $50 speaker approach and just get good bookshelves since they can be re-purposed to nearly anything if I decide I need better. I don't want to cut holes in the ceiling but I also don't want little tweeters chirping from the ceiling and then the balance is that I don't want huge MTM bookshelves hanging from the ceiling to catch someone's head.
It's really hard to find good resources on atmos in general from the end user experience, relative to finding material on subwoofers or the mains. Surround sound in general I suppose lumps into this, it shard to find good education and resource material on surround sound compared to the LCR/Sub stuff. Surround just seems to not get the emphasis, as I understand it shouldn't, it's extra. I certainly subscribe that I'd rather have the better LCR/Sub option going before worrying over having higher quality surround/atmos speakers. I just don't know how much it matters for atmos. Personally I found surrounds not to be all that important relative to the mains. I can't measure them dynamically, but anecdotally mostly what I hear from surrounds over the years is some little details, mids and treble, nothing profound, little to zero actual dialog, just background noises, effects, which are interesting and nice, but nothing that seemed to scream the need for high quality speakers. But, this is from a movie stand point. I'm sure the game changes a lot with the newer surround mixers that will better use surround and atmos (dolby surround upmixer) and then I can totally see needing good speakers to bother with that.
All of it is hard to digest since without auditions it's blind every time.
Very best,
