Hi,

Thank you very much for the explanation.

I want to ask you another question:
– If we have a line-array with 12 boxes and we want to compensate the HF for the distance on the top boxes and attenuate the HF on the lower boxes. Assuming we are doing that EQ using IIR, how can we make the FIR filters so the phase is aligned along the whole 12 boxes, and the delay as well?

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.
