Does the rotation of tweeter on the front doors with the High End sound system have any actual function other than dazzling passengers as it spins?

Is the tweeter proper superior sonically in any noticeable way to the standard tweeter?

 

I have heard people say they think they sound a little better, but thats not worth much...

 

The tweeter is likely marginally better but the improvement is mostly done by the additional speakers
The rotation is simply for show.

 

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
