SET amps and speaker sensitivity.

Hi there. Just for the aspect of learning and future knowledge, can a host of folks explain how to match SET amps like for example, the Lamm ML2.1's to speaker sensitivity.

We can even get away from the Lamms, really any SET amp. How do you match those to speaker sensitivity and what is the relationship between the two? What dB level is considered "sensitive."

Just curious and always wanting to learn!

Cheers,
Peter

A good rule of thumb for watt/dB combinations is 4w/93dB where every 3dB decrease in speaker sensitivity requires double the power wattage from the amp. Hence, 8w/90dB, 16w/87B, 32w/84dB and so on.

This was taken from a review of the Dared 845 amp. The reviewer was using the 18W Dared SET 845 amp with 84 db sens.Apogee minor speakers and had no problems at all with power.
