So I'm considering ditching my Sonos Sub. Without TruePlay it sounds like mud in my room (thank you Sonos for not facilitating TruePlay on Sub without a soundbar, more money down the drain).
I'll probably get a high quality, 12 inch subwoofer and connect to the Amp's subwoofer out.
If I do this, what kind of control will I have in the app as compared to Sonos Sub? Will I still have crossover setting? Sub volume?
