Sensitivity level of these speakers is high, but the 1 watt/1 meter level can be misleading. They are 93db with 1 watt/1 meter, but a line source does not lose sensitivity with doubling of distance like a typical point source. With a 1 watt input at 2 meters they are equal to a point source that is 96db at 1 meter. At 4 meters with a 1 watt input they are equal to a point source that is 99db at 1 meter/1 watt
These speakers are easy to drive and can be driven with low powered SET amps, but an amp with a high dampening factor and good driver control is recommended.
