Old dog new tricks, still learning FIRd-M. Thank you in advance for your attention and assistance.
I’m blessed that a retired EV engineer has found and sent to me Magnitude response .txt files for the 25+yo XLine speaker cabinets I’m still using. However, I’m not yet able to properly import them. I don’t know how to modify them in Notepad++ to create an empty phase column, but I’m hoping there’s a way to use just the Magnitude data. I’ve tried the Magnitude only check box, but the response curves don’t look right at all.
I tried to attach one of the files FYI, but this portal doesn’t seem to allow it –
