Most Klipsch reference series are greater than 92db efficiency, and sound excellent.I am sure most of the models are below three grand.I ran a pair of Klipsch kg4 with a NAD 3240PE and they sounded great.The 3240 was only 40watts per channel but this combo could rattle the house and the sound was clean.The kg4 are no longer made but anything in the refernce szeries will give you excellent sound without having to mortgage your house.
