[I got Atmos-OT in another thread so am looking for some opinions in the proper place now.
I'm wondering what you guys recommend for a new Atmos ceiling/height speaker installation. I have 4 ceiling speakers now, re-purposed regular bookshelf speakers, but I installed them some years ago and there are now speakers that I believe would allow me to do a better coverage/installation job.
The room is 12'Wx18'Lx9'H. The room is fully treated for the base 7.1 speaker installation; 2 subs, all there's room for. Two "gotchas" for your consideration: the Front LCR are 6' from the front wall and can't be moved. There is a "cloud" ~half way between the LCR line and the MLP (pretend it's just me); this treatment does far more than I ever thought it would, and I really really want to leave it there, so pretend it's also immovable. The MLP is roughly 2/3 of the way down the room, so say this is roughly the 7.1 word picture going down the length of the room:
Front wall/sub - 6' - LCR - 3' - cloud - 3' - MLP/surrounds - 6' - Back wall/surrounds/sub (Hope that helps...)
I am also willing to (plan to actually) buy a new pre-pro/AVR. So if you think what I want is 6 ceiling/height speakers, don't be afraid to say it, I can only do 4 now. But considering the size of the room and that it already looks like a speaker breeding pen, I'd prefer to keep it to 4. I would also be getting new overhead speakers, in-ceiling not an option, so surface-mount of some form again.
Here's what's bugging me: See that 6' "gap" between the front wall and the LCR line. Does it need to have coverage? It doesn't now, and if it should have, heights rather than ceiling? Would coverage there be more of a "frill" rather than a necessity? Something to add in later, but it would require a 13.1 pre-pro so best at least considered
If 4 overhead speakers are enough, would you put them symmetrically on either side of the cloud? (That's roughly how they are now.) Or how about over the LCR and side surrounds? Do I need overheads behind the MLP? The rear surrounds seem adequate, but IDK, haven't tried another option. Thanks.
One other thing: right now the overhead speakers are powered by 2xstereo amps. Excessive, and I sure could use any freed-up space if I removed them. So I was thinking I could get a new AVR and use it to power just the overhead speakers, and power all the other speakers with the existing separate amps. As you know, going past 11.1 (4 overheads) gets you into another league of pre-pro/AVR pricing, with somewhat less choice for now, so it really needs to be worthwhile to do that (whatever you think "worthwhile" means...).
