>> When I loaded the FDS file into my FIR Designer M, I received the following message:…
You have version 4.3.15 and the latest is 4.5. To update, ensure “Check for update at program start” is checked in Preferences, then restart FIR Designer M and watch for the Update window.
>> I noticed that you used a Cosine tapered window. Is there perhaps some another window
>> type that could produce a more pleasant, warmer sound
Factors other than the window have much more effect on the perceived warmth of the sound, such as the target response, using single measurements instead of spatially averaging measurements, and the amount of fine EQ. A “flat” target response is often perceived as too bright and harsh, and this can be changed on the System Target tab by adding slopes on the “Curve” tab. Fine EQ – such as with the 12th octave smoothing on the Auto Mag and Auto Phase tabs – may also have an impact. Try changing the smoothing to 1/6th or 1/3rd.
>> something that reduces the metallic character and minimizes ringing as much as possible?
Perceptable pre-ringing can be an artifact of trying to make the processed loudspeaker linear-phase, since the FIR filter can have significant taps before the FIR filter peak. However I’d suggest first experimenting with spatial averaging and using a System Target that has some roll-off towards higher frequencies.
Respectfully, most of these questions relate to best practices for loudspeaker tuning, which is beyond the scope of our support. We can explain how to achieve your goals using our software, but the goals themselves are completely for you to decide, either from other learning or experimentation. We don’t advocate for specific tuning approaches.
