Bass driven floorstanders?

Chris - I'm not sure what they sell for used OR how they'll compare to some of the other speakers suggested to you -  but for me, bass from the Totem Forest speakers has been a real surprise.  Early on with them, I'd considered getting a sub.  That is no longer necessary.  Two keys to getting great bass from them were 1. proper placement - nearer together rather than further apart &  2. adequate amplification - the quality of the bass with a Class D amplifier (Taranis from Merrill Audio) is excellent...deep, well-controlled and nuanced.  Cosmic Hippo by Bela Fleck is a great track for plumbing bass depths, as you may know.  I would note, bass from the Forests, even when driven by 78wpc Class A/B tube amps, did improve greatly once I found the proper placement for the them.  Placement takes priority over power in my experience.  Hope this helps.  Good luck in your search.

Vandy 1Cs it they're not too large…I had a pair of 1Bs years ago and the transmission loading works very well to give that 8" driver some mojo…great speaker for the subless.

  vandies 1ci are on top of my list, but I will probably loose the mid/tweeter clarity of the Regas.... I think i should just add a sub, even though I have always resisted this... the Svs sb 1000 is on my list (sealed box), and I will send signal using the pre-amp out of the marantz, and cross it over at 50 or 60 hz, frequency at which the Regas drop significantly in spl.  If this does the trick, I' ll get a second one later to have even even bass in the room.... I' ll report when I do it, very very soon I hope.
