I use 4 Atmos Onkyo speakers to my Denon AVR X5200W and am really excited what's even feasible to sound. Have the Setup Dolby Atmos 5: set 4: 1. Too bad that I now had to lose my Surround Back for. It is very important at all, to be run through the calibration after connecting all speakers. If you want a room-filling sound should buy these speakers. Who are the too cheap just have to buy the Kef, as does a pair of 799 Euro. Sometime also I'm going to buy better, until then this rich Onkyo first. I can definitely recommend it further.
