Motor force.

Motor force potential or factor...very different than motor force.

BL - The magnetic strength of the motor structure. "Expressed in Tesla meters, this is a measurement of the motor strength of a speaker. Think of this as how good a weightlifter the transducer is. A measured mass is applied to the cone forcing it back while the current required for the motor to force the mass back is measured. The formula is mass in grams divided by the current in amperes. A high BL figure indicates a very strong transducer that moves the cone with authority!"

Correct. Motor force was too broad, as it changes with many many variables.

Ugh....the thiele/small parameter represents a motor force factor....it requires actual current through a coil to make real force.

And a high BL figure doesn't indicate a very strong transducer...high BL^2/Re does but we must consider mass and suspension as well to determine how the cone is moved....aka Q factors.

The12volt.com....be cautious, although they're usually pretty spot on.
