Simple Bass Equalizer for Closed-Box Loudspeaker Subwoofers
Vladimir E. Filevski · 2008
Simple bass equalizer for closed-box loudspeaker subwoofers is proposed, consisting of a second-order low-pass filter with a low enough (e.g. 30 Hz) corner frequency, and with Q factor equal to Qtc of the closed-box. It is intended to be used with a closed-box loudspeaker with Qtc between 0.577 and 1, and corner frequency f3higher than that of the said low-pass filter.
