We are trying to test the FIR filter in AWD 5.16 as a xover in a two-way loudspeaker configuration. We use the rePhase tool to produce the parameters for the FIR filter, but it does not work. When we test it with a mic. and REW, it gives a whistling sound but that's all. Do you have a full example (AWD file) of using the FIR filter to control a 2-way loudspeaker?
