    Hi,

    I’ve contacted DFM asking for the IIR parameters. Please let me know which information you need in detail.

    Regarding the Multiway FIR I have some questions:
    – We mainly use multi-way speakers with active processing (no passive crossovers). So, I want to know the differences (advantages and disadvantages) between making the X-OVER using IIR HPF and LPF and enventually All-Pass filter for Phase slope correction, and then use a FIR in the input to flattern the phase from around 400Hz and above – and using FIR on each way instead of IIR.
