I can tell you that I successfully used Guarneris with Rel Strata III. This is a sealed box sub with tremendous flexibility. The Guarneri are very refined. Make sure you get a great deal. They sell here all day for $4500-$5500 used and this is BEFORE the next Guarneri is introduced.
As an aside, the Guarneri might be the most beautiful audio component I've ever seen.
