A:AnswerYes you can buy these speakers separately. Yes they are sold in the store and we have ours on a short stool behind the couch but you can hang them as well.
A:AnswerIt is better but still not fixed. It doesn't unpair every time but I would say about 40% of the time it will either lose the surround sound setup you create or will lose any custom settings you create. But agree with you that the speakers are great and it is too bad the app isnt more reliable.
A:AnswerInstall is pretty easy if you follow the on screen directions. Keeping everything paired and setup is a bit of an issue with the App. It will lose your custom settings regularly and you will have to set things back up again and again.
A:AnswerGuess depends on how big your room is. One should be fine but if you have 2 you can use the app to set them up in stereo. I think the stereo sound is good, for what that's worth.
