The manual that covers Yamaha NS10, NS15, NS18, NS20, NS30, NS20A and NS30A does not give a sensitivity rating. My guess is they are very efficient. The impedance is 8 ohms and maximum continuos power is 30 watts.
I had excellent results running Living Voice Auditoriums with a Scott LK-150. I also had excellent results with a Sherwood S-5000 on the same speakers.
