Dolby 7.1 surround sound was pretty easy for me to resist; $700 plus for a new AV Receiver and another $700 in speakers to add two more channels behind my head? Nope. I'm good sticking with 5.1 surround sound. So to even think about 9.1? Hah!
But Atmos, Dolby's latest sound technology seems a lot more impressive, and may be a lot harder to resist. Think of it, literally, as 3D audio. The system is designed to deliver sound from above you, not just around you. When utilized properly, it fills a room with sound, and gives filmmakers the tools to place individual sounds exactly where they want them in the theater space and move them around.
And, unlike 3D movies, I don't think it's a sucktastic gimmick. (All due apologies to Mr. Cameron and Avatar, but, most movies didn't do 3D nearly so well.)
That said, this was going to be a really simple column. Dolby Atmos sounds really cool, but my fear was that you would have to spend a grand or more on a receiver that supports Atmos. And then you'd have to mount FOUR speakers in your ceiling. And there's not much content mixed for it yet. Like 7.1, it could be an easy pass.
Turns out I was wrong on two of those counts. You can have Atmos even if you a) don't have all the money, and b) aren't allowed to cut holes or pull cable through the ceiling (with caveats). But before we talk bargain receivers and Atmos enabled speakers, let's talk about the Atmos technology itself.
