AB  - The subject of finite-duration impulse response (FIR) and infinite-duration impulse response (IIR) filters used to implement loudspeaker crossover filters is addressed. The filters have been tested on the TM32020 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.
