In this paper a special type of magnitude complementary IIR filter pair with variable transition bandwidth and impulse response length was used in order to examine the effects of these two characteristics on subjective perception of the reproduced sound. Two types of listening tests were performed. In the first type of tests sum of crossover outputs was compared to the original signal. In the second type of tests the IIR filter pairs were compared among themselves, as well with linear phase magnitude complementary FIR filter pairs as a reference. The results of the tests show that overall differences are not significant. It was found that considered filters are suitable for loudspeaker crossover applications.
