Unlike other many other tweaks - the science behind this is not flaky. THIS IS REAL. The improvements are described as;
This accurately describes what I gained when I soffit mounted my speakers into a wall and made them flush with the wall with a smooth transition (totally eliminating baffle edge diffraction altogether). This is why all high end main monitor sound at a major $multi-million recording studio facilities is soffit mounted (in the walls - and they have been doing this for decades!!).
This sounds amazingly cheap for something that will certainly reduce edge diffraction from sharp speaker baffle edges. I doubt it will eliminate totally the problem but I believe the reduction will be audible in most cases.
For $50 bucks what do you have to lose - try it and perhaps you will be so impressed that you will be designing a soffit mount for you next set of speakers!
Only caveat that I see is that this will certainly change the dispersion pattern - so you may be compensating for something the speaker designer has already considered (for example why else do you see tweeters offset from center? - because this mitigates horrible edge diffraction issues)
Sound waveforms from your tweeters are shorter in length than the width of
your speaker cabinets. A 2000Hz waveform is 18cm or 7" in length, for
example*. We hear information up to approximately 14kHz on average. These
waveforms are being randomly reflected by your speaker baffles and edges to
your listening position slightly out of time with the original event. Not a good
thing. These waveforms carry the first arrival and higher harmonics of your
midrange along with all things high frequency. Our product removes this
almost as if you had taken the boxes away.
We size to speaker and professionally cut high density real wool felt (accept
no substitute) tweeter surrounds or fascias that absorb and quiet this
interaction.

What you will get when this is removed is a clearer view into your
stage and recordings. What the microphone captured is revealed in your
room without the distortion to time (body) and phase (space) caused by early
reflection. Space opens up, deepens. Vocals and instruments appear more
truthfully in that space, rounder and more physically right.
