Thank you. Now I succeed to import mls files. But I have problem with design of crossovers which is designed in VituixCAD by another person. I can’t find some blocks like LP1, BEQ in your list. Attached you can see details about the crossover I want to design. Could you help me to design such crossover in your software. Measurement files of that speaker are files which I sent you in previous emails. It seems to me very complicated. I studied your tutorials , but still I’m not able to design my first crossover in Eclipse.
LP1 sounds like Low-pass 1st order. In our software, choose a butterworth low-pass and set the order to 1.
I’m guessing BEQ is just a parametric filter.
Regarding your analog circuit block diagram,
– the tweeter has two HP2 (high pass 2nd order) filter blocks which combine to be a 4th order high pass.
– the midrange effective has a 4th order low-pass, a 4th order high-pass and one parametric
– and the woofer effective has a 7th order low-pass, one parametric and a LEQ (which I don’t know). I think this 7th order is a mistake. It’s probably supposed to be a 4th order low-pass and a 3rd order high-pass.
Regarding your target diagram,
– the tweeter appears to have a 4th order linkwitz-riley high-pass
– the midrange appears to have a 4th order linkwitz-riley high-pass and a 4th order linkwitz-riley low-pass
– the woofer appears to have a 4th order linkwitz-riley low-pass and maybe a 3rd order high-pass.
In FIR Designer M you can use the IIR filters tab to implement all of these filters, and see the summed response. Choose “HPF LR” and “LPF LR” – both 4th order – and “HPF Butter” set to 3rd order.
Regarding your measurement files, they don’t appear to be useful; they are way too chaotic in both magnitude and phase. I suggest you go back to whoever made the measurements for you and have them redone. If they still look like this, maybe have someone experienced check the measurement equipment and measurement setup.
