most accurate loudspeakers....

if you mean a 'flat response throughout the range' there are are too many models (try hundreds)to name them all. i suppose over several decades, AR hit the mark as many times as anyone, and early on, wrote the book.....on the other hand, nothing sounds more like a real trumpet, than a trumpet played back through a klipsch of nearly any model, new or old...now lets start naming the hundereds of others....

It depends on what you mean by "accurate."

A good place to start is to check out what most of the prestigious studios and mastering engineers like to use. Full range accuracy at both low level and realistic live sound levels is actually quite rare in home hi-fi.

Viridian- I do like your thinking. If my man isn't to remote, he should go to dealers in his area toward the end of the week and see if they won't let him take home and audtion over the weekend. The latest Merlin monitors are getting a lot of press about their "accuracy". Their acoustic suspension designs as opposed to ported so their bass may be tauter and with better timbre than the latter designs but with less abundance. The word accuracy makes me think of Dynaudio, as well (Contour series and up). Chances are, my man may not know what's gonna groove him the most. In home auditions are the way to go.
