Non SVS subs with app or remote?

I love my SVS SB16s but would like something a little better for music. I'm also addicted to the app and can't fathom getting up to change volume/phase etc.. I love being able to immediately hear the difference in my listening position.  I know the higher-end REL's have a remote but is anyone else making a sub as good or better than the SVS with an app or remote?
