There is much debate about the best type of filters to use for equalization of loudspeakers in rooms and cars and a number of products marketed as providing an “ideal” result. This workshop seeks to explore the pros and cons of equalization strategies using IIR or FIR filters in such an application. It presents the engineering facts of both types, looks at the evidence to substantiate claims that absolute and relative phase is audible, and presents case studies for real world FIR and IIR implementations.
