    This is a good sounding sub if you want to only use it for movies. But for using the RCA inputs for two channel or for any other reason you have to use an app for any of the settings, which to me foolishly. Then to be even more foolish to connect wireless you have to purchase an additional part for it to be able to connect wireless. It needs to be able to adjust and function by built in controls, needing an app to control a sub to me is completely stupid. Then you have to purchase another part to be able to connect wireless.

    The app (Martin Logan and ARC) sounded promising

    Still trying to get it integrated with my KEF LS50 Meta speakers, so I might become more sanguine about it. The app (Martin Logan and ARC) sounded very promising, but didn't do much for my set-up. It almost seems like they're more useful for ML's marketing than real world benefits. I've tried also a KEF 10 Kube, which was sounding much better - I might go back to it and return the ML. The quality of the built is NOT that of a $900 sub. One of the feet already came out when I've tried to take it out to change the speaker orientation to front firing. It seems the body is made of cheap particle board, not MDF.
