I did not set them up inside yet but they are so easy to take down that I will. We were having a 4th of July get together so I wanted to have them set up outside. I do like that the Denon receiver allows me to switch between mono and stereo in zone2 without have to wire them in parallel. I have them mounted 18 feet apart 9 feet high and angled slightly downward. They sound great in mono and stereo but if you are standing anywhere in between them stereo is better. Once I go beyond the boundary of the speakers mono works best. I still want to add another 2 on the other half of the patio and then I'll wire the two on the right together and the two on the left together and see how they sound in stereo when I'm out in the pool area. I may end up having to run mono with all 4 hooked up. It's definitely something I will have to experiment with.
