AB  - The magnetoelectrical performane of a loudspeaker driver is often characterized by the force factor B1, in units of tesla-meters. However, the parameter B1-Rc, in units of newtons per -watts, which can be described as a force conversion Fme, allows more meaningful comparisons of magnetoelectrical structures, while a second force conversion factor Fam, with units of -watts per newton, similarly allows comparison between the acoustomechanical characteristics of different cones. The efficiency (ratio of acoustic watts out to electrical watts in) of the driver is derived by multiplying these two force conversion factors together and squaring their product.
