Someone on here did testing between the regular and spinning tweeters using acoustic measuring equipment, and found the spinning version is a little brighter sounding
I swapped spinning units into my car and agree they do sound better, in addition to being a great parlor trick for passengers
I don't know if it was placebo but I feel the crispier sounds given same tracks compared to standard audio equipment but it was still too minimal to me
