A dual-band equalizer for loudspeakers

Many digital equalization methods for loudspeaker systems have been propose d in the literature. However, a number of these do not equalize the low-fre quency components effectively. A new method is proposed, which involves the incorporation of a warped filter into the conventional equalization design . Computer simulation results show that the proposed method is able to impr ove the performance of the equalized response at low frequencies while main taining that at higher frequencies.
