What are some good example of baffle design to improve diffraction

Ahh, an assertion based on someone else's assertion of someone's assertion based on... Get out there and test the assertion for yourself, even just by chatting.

No it is not a matter of academic authority: Toole and Harmann R&D department have been investigating for years the preferences of their prospects: you do not become the Nº1 of the industry in the world just pleasing your golden ears.
 
One good example is when I got to see a Dali up close, really close. I'd seen the overall paintings many many times in books and prints etc and to be honest not really wowed by them as some seem to be. Then I got up close and saw how much detail there was in each and the vibrant colours (the way this one was lit anyway) - suddently I grew a strong appreciation! Something I liked about it that wasn't apparent from a distance.

Well, your example, Dali's paintings are extremely tiny compared to the sound stage of the stereo we listen to at home. Also they are microscopic by nature. The projection area of the high end stereo system is much larger, even larger than Jackson Pollocks' paintings. 😉
 
Of course, I agree . I was posting in reponse to GDO's assertion that those who choose to listen to high directivity speakers can't possibly enjoy it and therefore most only use them in a pro setting as tools..

So yes, I agree, there is no point making that assertion and implying that wide dispertion is correct. 🙂


I was not referring to reflections per se, but "how to listen" differencies (pinpoint vs. eterical imaging preference etc)
 
I am looking for a few baffle designs to improve diffraction.

the most effective way to improve diffraction is to scatter it, for example:

Maybe it's that small head-movements change the sound so much?

Yes indeed, the constant small changes in tonal balance and imaging break the magic and sound totally unnatural to me.

I criticized the narrow sweet spot, but this happens both in mono and stereo.

A natural acoustic sound source do no behave like this. At least, if the source moves slightly it might sound different, but if you move slightly you usually hear no difference.

Btw, stereo means literaly solid, not pin point! I need solid soundstages!😀
