AB  - The aim of this paper is to present a new generation of EQ. It provides a way to ensure phase compatibility from 20 Hz to 20 kHz over a range of different speaker cabinets. This method is based on a mix of FIR filters and IIR filters. The use of FIR filters allows a tuning of the phase independently from magnitude and allows an acoustic linear phase above 500 Hz. All targets used to compute FIR coefficient are based upon extensive measurement and subjective listening tests. A template has been set to normalize the crossover frequencies in the low range, enabling compatibility of every sub-bass with the main cabinets.
