Mr. Linkwitz' presentation (AES)

[gainphile]

The title is "Accurate sound reproduction from two loudspeakers in a living room"

It's quite amazing how he can explain complex nature of sound reproduction with such simplicity. Anyone who is about to invest on pair of loudspeaker should hear this beforehand.

Wow interesting talk. Is this authorized by Linkwitz?

Yep. You can download the very same lecture in MP3 format, and Print (or view) the Powerpoint presentation right off of Linkwitzlab.com. The info is given at the beginning of each video segment.

I think it was put on YouTube just to widen access - to "get the word out" about his findings. Some folks don't have Powerpoint, or perhaps just wouldn't have searched his extensive site.

Yes, these are widely available materials. Putting in on Youtube just to make things easier I guess.

I listened to the presentation yesterday and it was
very enjoyable to me.

I like the fact, that Mr. Linkwitz postulates some design
goals, but does not force a certain way how to get there.

There is place for different approaches. This is what we
seem to forget sometimes, even when discussing in
this forum.

For different living rooms, different setups may be suitable.

In the discussion after the presentation he states, that
in a very small room, where you can't keep the minimum
distance of 1m from the loudspeakers to the next walls,
an omnidirectional loudspeaker may be more "benign" than
a dipole.

The uniform dispersion of sound vs. frequency is important, not
necessarily the directivity index iteself. Even though, with a wide
dispersion loudspeaker you will usually prefer smaller
listening distances.


There is a further key statement of Mr. Linkwitz to which
i would agree:

Most commercial designs do not account for uniform dispersion,
even though the benefits are known since many years.

Thanks for the link !

Was I the only one that though all that was boring as hell? I got up to part 5 and just about lost the will to live. I know it wasn't the content, acoustics is an interesting subject.

I used to work in a photo shop in Santa Rosa, California and had
Mr. Linkwitz as a customer. . .I made a statement to the effect that
his name was the same as the fellow who created the Linkwitz-Riley
cross-over alignment. He admitted that it was him and that ended
the converstation. . .Didn't seem to interested that a DIYer who
worked in a photoshop would even know who he was. Not a
conversationalist but knows his math. I think I gave him the wrong
change and he had to correct me. . . Great impression. . .

The slow pace of the lecture, and the fact that we know the subject, make the presentation somewhat boring for me.

Thank you Gainphile for "youtubeing" the Linkwitz session! Very interresting talk indeed.
