What are some good example of baffle design to improve diffraction

[GDO]

Why do people I experience appear to prefer their headphones to home stereos?

Headphones are definitely diferent animals that provide different experiences.

Convenience anytime anywhere is also a big plus.

Most home stereo equipment suck, ghettoblasters dominate on a statistical basis too...

 

[GDO]

The sound is like putting earphones on, even they are in a 3x5m room with concrete walls!

Sure, but i have headphones for experiences like these,and in a much more convenient form factor...😉

Sure: Toooole!😀

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. 😉

Btw, as said before,maybe in part because no loudspeaker is acoustically small enough, i don't like the sound of any speaker at less than 1m. Don't know why, but...🙄

Maybe it's that small head-movements change the sound so much? That's very unnatural and something I find annoying.

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)

 

[keyser]

The point is to optimise it to be flat on and off axis and listen to it mid/nearfield.

I agree. My preference is to listen at about the critical distance* for mid and high frequencies.

Can anyone recall the last time diffraction was mentioned in this thread? It keeps drifting away, I wonder why that is

I am looking for a few baffle designs to improve diffraction.

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

In what way is it scattered and what exactly does that improve?

Diffraction itself is probably not important as the other factors for most people...

 

[scottjoplin]

Mmmm, directivity seems to be the in word

 

[graaf]

just use Edge software and look at the response

well for most people what is fancy is important

I don't quite follow Graaf. I am familiar with the edge, but what should I sim exactly?

What do you refer to as "critical" distance for mid and high frequencies ?

 

[GDO]

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!😀

 

[graaf]

same thing as always - the baffle shape and the speakers placement on it and mic position on the listening axis at the typical listening distance

am I clear now?

Among other stuff i use Jordan's JX92 in VTL cabs, and precisely i find that fullrangers small nastinesses (breakup modes) are mostly noticeable in nearfield.

I found the nasties of the JX92 hard to listen too at any distance.
