Musical subwoofer under $2000

To better understand what you mean by a "musical" low frequency producer.

Imagine you had two units at your home for audition individually during the same session. They are both properly positioned in your spacious room and adjusted to a point were you can not discern were the speakers end and the unit takes over the low frequency output.

Played individually turning each one off, its apparent one displays a noticeably greater sense of extra low frequency fullness (not loudness) of your main speakers presentation than the other. Which units presentation would you consider to be more musical?

First and foremost, I’d recommend getting two subs instead of one. In your price range you can get a pair of SVS SB2000 Pro subs that’d likely sound great in your system. Best of luck.

You want punch in the gut tight bass? 
or blend just a little something down low?
