The Spendor S-8 is surprisingly full range (quite amazing for a 2-way) and worth looking into. This speaker goes quite low, is capable of filling a large space, and throws a big image even in a small room. In other words, it is quite versatile. My only quibble is that it has a slightly "plastic" sounding coloration.
I don't have extensive experience with the DeVore Super 8, but what I heard at CES (actually, at the nearby T.H.E. SHOW) was quite promising. This is a VERY musical, easy to listen to speaker, that, unlike so many modern designs, does not sound lifeless and constipated. It was hard to tell how good it sounds coupled with "normal" electronics because it was hooked up to some quite pricey Shindo electronics.
I recently heard the latest ProAc speakers and they too, sound reasonably good. I believe one of the models I heard was in the $4,000 range, the other was $2,500.
Some of the Nola (formerly Alon) speakers might fit the bill. The use of open-back dipole radiation for the midrange/tweeter gives it a big, open image.
