A Loudspeaker Management System With FIR/IIR Filtering

Document Thumbnail

Most digital loudspeaker processor systems use cascaded IIR filters to perform the crossover function and system equalization. This work presents a multirate platform which allows FIR and IIR filters to be freely combined in each output channel. The pros and cons of both filter types are discussed and some techniques to obtain suitable FIR filter coefficients are described. Dual-range AD conversion satisfies the need for high dynamic input range, while look-ahead peak-limiters in the outputs avoid clipping and mechanical damage without introducing noticeable distortion.
