OK, so I've had my Atmos setup running for about a week now, using the OWM3's as front/rear heights. The AVR is a Denon X4200W, with an added two-channel amp to power the rear heights.
I'm still experimenting and adjusting the trim levels to find the right balance with the rest of my system. Without a basis for comparison, it's hard to know how to rate them, but my opinion so far is they do an adequate job as Atmos speakers in my room, keeping in mind that where I have the rear heights mounted doesn't truly follow Atmos guidelines (they're supposed to be directly above surround back speakers, which I obviously don't have, since I'm running a 5.x.4 configuration with my seating directly against the back wall). Audyssey calibration set the crossover for the OWM3's to 80hz for the front pair and 90hz for the rears, probably because the front pair are pointed more directly towards the MLP, whereas the rears are a pointed a couple of feet in front of the MLP, so its measuring the speaker's off-axis response.
Both pairs of speakers are flush-mounted using the bottom key-hole slots, so they're both pointed 45° downwards (more or less, I made sure there was a bit of an air gap so I could add some padding directly over/under the mounting point to very slightly tilt the speaker a few degrees towards the MLP.
Listening to Atmos and DTS:X demo material, it sounds quite impressive - DTS:X/Neural:X in particular employs the height speakers in a very aggressive manner, so you really hear a difference. DSU upmixing is more subtle. So far, I've only watched two Atmos blu-rays: 13 Hours and In the Heart of the Sea, both good films, but I didn't find either used Atmos in a very active way. I obviously could hear the overhead effects in loud/action sequences, but I didn't get that feeling where you're immersed in a 3-dimensional cacoon of sound that some people have described.
My verdict so far - it makes a difference, but it's not a night and day difference. I'm thinking better speaker placement might help, and possibly better speakers as well, but I'm not going complain, considering the price I bought the OWM3's for (if you're in the US, I very recently saw the OWM5's drop to $99 on Amazon, so it may be worth considering if you want to stay with the OWM form-factor, but want something a little more capable than the OWM3).
As I mentioned, I'm still in the tweaking the setup. I'll be re-running Audyssey in the next day or two; when I first ran it last week, both of my cats were in crazy mode running around all over the place, so I don't think I got the most reliable calibration that first time around
