Most speaker drivers have symmetrical Fs impedance peak but there are drivers (woofers and also tweeters) that have asymmetrical Fs impedance peak, which looks 'strange' intuitively if you saw many raw driver Fs impedances. What is the source of this and what are the realworld consequences (mainly audibility) of such an impedance? Thinking mainly about woofers where tipically using the drivers at it's Fs.
