Musical Sub to pair with Mani2 Sigs..

Looking to get a very musical sub to pair with Mani2 Signatures..

Any thoughts? Opinions?
I'm using a Rel Storm III and it integrates nicely with my Mani's. . . . incredibly musical . . .

The Mani's hardly need a sub. I cross it over at 30Hz, and it covers those deep bass notes only.
I second the REL brand - they mate seamlessly with just about any speaker. Very versatile.
I'll go out on a limb here and say maybe a Totem sub.
I looked at the totem subs, but I don't get the feeling that they are really as stellar as the Mani's.. Maybe I'm just skeptical because I love the Mani's sooo much.

I heard that REL sold to Sumiko in 2006 and I have wondered about the quality since then.. Can anybody speak on this?
I first bought a REL B2 and was happy; then I upgrade to the B1 - extremely happy. I use it with some Sonus faber Cremona Auditor Ms. I prefer this setup over my previous all Dynaudio monitor and sub combo.
