I have a speaker with the below specs that I currently use as a subkick microphone (speaker wired in reverse)
I would like to add a passive low pass filter and understand that I would probably need an inductor coil, my question though being an absolute electronic newbie, what kind of coil would I need and would this cause problems to the electronics of my sound card receiving this signal?
much appreciated legends.
