The pro monitors that have been recommended here are all certainly appropriate, although I'd personally choose the Lipinskis only for near field use. If you want to go another way, consider the Ref 3a deCapo. It is essentially a direct coupled mid/bass driver in a ported cabinet (augmented by a tweeter with a single capacitor for protection in lieu of a full blown x-over network). These will compress dynamics and don't offer much bass below mid 40 cycles (depending on your space), but they are also very neutral and revealing.
