Abstract
A filter for equalizing the frequency response of loudspeaker systems includes at least one band filter section () comprised an n-order high boost or cut shelving fitter () having a break point frequency, ω, and an n-order low boost or cut shelving filter () having a break point frequency, ω, wherein ω<ω. The order, n, of at least one, and preferably both of the shelving filters of the band filter sections can be selected for adjusting the slope of the shelving filter at one or both of its break point frequencies. The high and low n-order shelving filters forming the band filter sections have substantially the same gain and produce a resultant band gain for the band filter section. Gain correction is provided for the selectable n-order high shelving filter and n-order low shelving filter for correcting the resultant band gain to a base gain level.
