As I mention often (too often maybe, but hey...I’m an insecure attention monger!) I have been enjoying a new pair of Heresy III "Capitol Editions" (meaning they’re signed or have different finishes than stock...or something...mine are labeled Ebony but actually ARE "deep purple") for months, with 2 RELs I already owned...a simple tone generator from a test CD will tell you exactly how low the Heresy will go (so will reading any reasonable review) and I simply enjoy the room charging feel of a good sub providing that extra sense of realism to things. Without the subs and with these things on the floor where I think they belong, the Heresy will still display a powerful tone palette. RELs can be unobtrusive, they’re powered of course, and you can get ’em cheap as good ones like mine (Q150e and a Q108II) show up on Ebay frequently. I make my own REL cables from Canare Star Quad and Neutrik Speakon plugs. Read the recent Ken Micallef review in the June Stereophile...he experienced some strident tweeter issues here and there, but otherwise he seems to really like these things.
