For music, you’re MUCH better off with two smaller subs than one larger one and will still work fine for movies. In your system and room I’d take a hard look at a pair of SVS SB1000s that you can get for about $1000 for both and I believe will get you down to an honest 20Hz despite their relatively small size, which will be nice for movies especially. And the new models come with integration software/app that should make setup much better and easier. They offer a very generous and truly risk-free trial period (including shipping) that makes it easy and painless to give them a try. I’d bet big bucks you won’t return them. Best of luck.
