speaker with good low level detail

Can anyone give me a recomendation for a full range (or close)speaker with a fairly small footprint that has good low level detail? I will be using this speaker with VTL MB 125 monos and probably a Cary CD running dir to amps. This setup will be for a second system that will mostly be used for background music but I still want a rich,dynamic involving sound. I definately prefer to buy used and looking in the neighborhood of $1000.00.
Thanks
