    Installed as part of a new Home Theater system and the entire package is awesome. My in home consultant was responsive, listened to my objectives and installation was handled by a pro. Exceeded expectations.

    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.

    This is a beast of a sub! It only takes up a small amount of space. Was already a Martin Logan owner and fan. Buying the matching sub was a no-brainer. Highly recommend!
