If you don't mind the hassle of shipping, go ahead and try the Emotiva towers. They are some damn fine crafted speakers. The workmanship in the cabinets and just plain fitting is excellent.
Of particular note, they use a sealed cabinet. The top half is basically the new ERM-6.2 monitor mounted over a base section.
If you want to try something smaller you could start with those to see how they compare.
Or maybe the new ERM-6.3 LCR speaker:
They are also running a closeout sale on the smaller ERM-1 monitors for $149.00 each. These are the smaller version of the ERM-6.2's. They'd be worthy trying out and even using for a second zone.
