Why atmos? Wouldn't any receiver with a subwoofer out do? Many subwoofers have a crossover and you can could also wire your audio out through the subwoofer and then to your speakers if you really want.

There’s a difference between sub out and LFE. Sub out usually can’t accurately do frequencies that low. I believe LFE is Dolby tech too.
