I plan to use some fabric stain to make them black and ‘fade’ away as they are ugly and my wife is saying no way jose. We’ll see, they sure do improve the focus/clarity/presence of the tweeter output.
I agreed with this chaps logic regarding round vs square or non-symetrical and cut mine to be square and recessed a good bit away from the tweeter.
That would be an interesting application on line source speakers. My XR19s employ felt that which i use as left and right HT surrounds. The XRT20 and XR290 I have did not.
Plus no baffle, at least not in the 2ce Sigs I had years ago. I very much liked the sound but they were just too big and were sold during a move.
I’m still quite pleased with the calming and focus of the higher freqs. I don’t use them all the time but it’s a nice option and it improves many albums but certainly not all.
Focal speaker owners - I’m really curious why there is a systematic design bias towards NOT placing any anti-diffraction treatment whatsoever in any of Focal’s high-end speakers. Typically, with large baffle surface areas, the tweeters are extremely vulnerable to undesirable destructive interference - the deleterious effects can be seen in every Stereophile review waterfall plot of Focal loudspeakers.
Aesthetics is my guess. I know, it should be all about the sound but it’s not.
I used some Rit dye to make my natural, off white wool black or very dark grey. It mostly disappears now and is much more pleasing to the eye (in that one doesn’t really see it).
