Determining the of a loudspeaker (often referred to as Thiele-Small parameters or T/S parameters ) is essential for designing an enclosure that allows the speaker to perform effectively at the bottom of the audible spectrum. These parameters define the electromechanical behavior of the driver and are typically measured at low input levels where the mechanical behavior is still linear. Core Low-Frequency Parameters
(DC Resistance): The resistance of the voice coil measured with a DC ohmmeter, typically lower than the nominal impedance.
To accurately predict how a speaker will sound in a box, several key values must be determined: Fscap F sub s
