Cinema uses arrays and have to cover long distances.......different animal.
In a home Atmos system, the last speaker you need are wave guide or horn configurations....ie Klipsh/HSU. Simple......90 degree dispersion is the goal......not to many speakers on current market comply. CEDIA 2014 might have new products that conform.
I've been trying to find out what the vertical / horizontal dispersion values are for the speakers I had in mind for my height channels, the LSR 305s. I totally love the sound I get from my three 308s as LCRs and now I think I'll be running 5 of them for my base 5.1 setup, and then four 305s mounted not on the ceiling, but high up on my walls angled downwards as per the Auro 3D diagram which apparently can be made to work with Atmos pre-pros as well.

I have really high ceilings like 13 feet (a loft), but instead of installing actual downfiring concentric drivers, I'd like to stick to my active speaker goal of using all JBLs but I'm just wondering if this is a bad idea for the height channels at least. I don't own this place so I can't really cut out holes from the ceiling to install 4 in-ceiling concentric drivers, but I'm hoping with a decent Atmos receiver I can put my height channels on walls but angled down towards the seating area.
Can you tell me why waveguides are bad specifically? I mean, they don't all spread sound out more than 90 degrees, do they? I wish I knew whether these 305s would be decent as height channels prior to purchase because in that case I won't buy them. My upgrade plan is to get two 305s to finish my 5 channels, then add two more for 7.1 classic, then put all four of those as height channels and get two more 308s for my seating height surrounds and then end up with a 5.1.4 setup with near identical speakers that are all powered.
Am I crazy to try and do this? I figure I could upgrade to 7.1, then when I get an Atmos receiver try out the surround rears as front heights, then decide if it sounds good and the sound field is decent.
