I have been looking at the Dolby Atmos stuff. That's a ways off for me, but it got me thinking. They have speakers that aim up to reflect off of the ceiling to simulate ceiling speakers. I have a Denon 2113 that has the Dolby Prologic 2z. I'm in a rental right now so I don't want to mount the height channel speakers on the cieling. I 'm wondering if doing an up firing speaker like the Atmos speakers would work for the prologic 2z height speakers. Is it worth a try?
