Need some speaker layout help
My old Onkyo receiver died which means I suddenly have permission to upgrade an audio system that hasn't seen improvement in nearly 10 years. That's the good news. The bad news is I'm not sure how to best deal with an unusual room layout.
I'm buying a new Onkyo TX-RZ800 7.2 receiver for the purpose of being able to pipe HDMI TV signal via Zone 2 through the wall to my outside deck. Until now I uses an old Polk soundbar under the TV with the old receiver. The new receiver has the ability to do both 7.2 surround as well as having Dolby Atmos processing for use with in-ceiling or "height" speakers, which I know next to nothing about.
Given the extra features on this receiver, I need help with figuring out what sort of speakers to utilize with the new receiver as well as ideas for placement.
Here's the layout of the room:
Thanks in advance for any feedback!
