Yeah....but this works independently of the felt around the tweeter or midrange.I've tried it on diverse speakers like the latest Ryans, Wilsons, Quad 57's, and it works extremely well. Actually I can not recall a speaker where it did not work well. Both Ryans and Wilson ( Watt, Puppies have felt around the drivers).Being a dealer exposes me to many many different brands of speakers, so experimentation is readily available
No matter how much felt you place around the drivers on a baffle, the sound coming off of the driver tends to be hemispherical, with perhaps a bit more emphasis on the front. In fact when looking at dispersion characteristics of almost any driver the propagation 180 degrees off the forward direction is always lower than the forward direction. However signal still "bleeds", for the lack of a better word, directly against the signal from the other speaker.
You can try and cure it at the source, but the issue will still remain in the center between the speakers.
Many have criticized tweakers for not addressing room acoustics. This however, is a very"out of the box" means or addressing fundamental , or at least what I consider fundamental issues with speaker placement. And believe me I have the levels and laser pointers to show for all the efforts I have made. They all help, but not to the degree this tweak does.
One caveat, if the speaker system is not time and phase aligned, these anomalies will be more evident. Also be aware that many pieces of software are also reversed in polarity, so if imaging gets worse try reversing polarity. For some odd reason the majority of my CD's are reversed.
