You have some good choices by other members so far. I would also add Montana speakers to the list. The EPS2s are 92 db efficient and are extremely happy with medium powered tube amps. They will play VERY loud VERY effortlessly, but handle any type of music with aplomb.
BTW, I had a pair of Coincident Super Eclipse IIIs and I would say their efficiency rating is exaggerated. Not to mention they couldn't fill my 26 X 16 room like larger speakers can.
