Abstract
In accordance with embodiments of the present disclosure, a method may include using an adaptive filter system to estimate a response of an electrical characteristic of a loudspeaker based on an error between a first electrical parameter of the loudspeaker and a second electrical parameter of the loudspeaker and adding a non-zero delay to the first electrical parameter relative to the second electrical parameter prior to calculation of the error such that the adaptive filter system captures a truncated non-causality of the electrical characteristic.
