If you want better than full range performance, the Rythmik is the best choice.
The SB-2000 is good, Audioholics rates it for a medium sized room based on its volume output, your space is a bit larger. The Rythmik is about the same in loudness.
The HSU is good (keep in mind shipping costs is an additional $80 on top of the $780 price tag, so $160 more than the Rythmik), gets ~6dB louder than the SVS (same difference as going from 50W to 200W), just doesn’t go as deep as the Rythmik.
I’d say the HSU would be the best for your sized space unless you really care about subsonic performance, where Rythmik is king.
