diffraction control

[dry martini]

Greetings-

Conventional box speaker owners, short and spreading waveforms produced by surface mounted tweeters are being diffracted by the hard surface and edges of your speaker cabinets and summing in out of time and phase with what is arriving at your listening position. www.diffractionbegone.com, my small enterprise, makes natural wool pads in a proper depth and density fitted to your speaker make and model to capture and remove that interaction and the offense to the linearity and time coherence your system is able to deliver.

Happy to discuss openly and answer anyone's questions. Hear your music, not your speakers. Thank you. Jim Goulding

A wee bump for the prosperity of what the microphone heard. Cheers.

Just remember that if you mount felt or use other kind of "diffraction control" you will need to follow up with crossover adjustments

I wouldn't be too concerned about that unless you have the wherewithall to make your own speakers from the ground up. As an aftermarket product, it has been unanimously a benefit. It seems that when diffracted waveforms sum into the direct radiation of the tweeter they cause an elevation in the frequency domain just north of the crossover that flattens out as a benefit. Then, of course, time and phase is preserved with their use, and that's a benefit. There is also less comb filtering, I am told.

In addition to the user comments at the link above, I have a ton of unabridged user reports I'm happy to share. And I sell with a money back guarantee so people can audition (they are removable) on their speakers for themselves.
