At first I was a bit skeptical because of the low power (100 watts maximum), but on the other hand Onkyo also has rather large output stages in their receivers and because it must indeed work scließlich. Once speaker at Amazon were available (because of the return if not satisfied), I could not restrain myself and have it ordered. After a few days they were already delivered. After unpacking I still thought that look more like computer speakers from (size because of), but no matter connect only once and configure. So, 2 front, 2 rear, screwed 50 cm below the ceiling upward radiating means mounting on the wall. As a receiver I use the Yamaha RX-3040 A and a Quadral Chromium Style 5.1 speaker system. Receiver menu asked the LS by Onkyo to Dolby Enabled and then leave the calibration room speakers (angle measurement). After completion of the calibration I have only changed the crossover frequency of the Atmos speakers to the subwoofer. The receiver has given 120 Hz, I set to 160 Hz. Now I have tested the whole a couple of days and am absolutely satisfied, Dolby Atmos course I could not test, but that will soon change. I hear all about the Atmos decoder, even stereo sources and that sounds good, you can effect the speakers no longer places, the feeling I have, anyway.
