I have 2 RSL 10S mk ii wireless Speedwoofers. They are very nice. They look like subwoofers, but since they are under my end tables, I don't see them unless I look for them. I have a HSU VTF 2MK5. It is long, front to back, so a bit awkward to hide. It sounds great.
I have 2 EP600s. Now, that is a really great subwoofer. I have 2 EP500s. Also great.
The RSLs were dirt cheap for excellent performing subs. The HSU is a great sub, costs $689, is musical. I like it. If you can afford an Axiom sub, you can't go wrong.
Good luck with your research and purchase.
