Abstract

This paper addresses the subject of finite duration impulse response (FIR) and infinite duration impulse response (IIR) filters used to implement loudspeaker crossover filters. The filters have been tested on the TMS32020 digital signal processor. In the case of FIR filters, a very compact form of coding has been developed which requires only one convolution to give both the high and low pass filter outputs. Listening tests were performed to evaluate the improvement in the off-axis frequency response obtained by using very high slope filters. An FIR filter for equalizing a tweeter response was also designed.
