Most beautiful speakers in the world ?

Siegfried Linkwitz had a secret sibling who is a plumber by profession?

Someone like Siegfried Linkwitz is yet to be born!

No one has emerged with the same blend of innovation, generosity (free knowledge), and practical success (affordable, high-quality designs). The industry leans toward commercialisation or incremental tweaks, missing Linkwitz’s fresh, science-first ethos.

Quite interesting drivers...

It's rather interesting how the vibrations are transferred to the corrugated aluminium membrane and the wavy membrane. The transfer of vibrations to the woofer is not so different from what Sony and other Japanese companies were doing in the 1980s. I recall a particular group of people experimenting with a corrugated aluminium membrane made from food packaging a few years ago, achieving quite good results. There is a YouTube video available somewhere.

Yes, the idea was to get the mid range in the coax as essentially flat rather than conical to avoid some of the interference with the tweeter. Because they were doing first order crossovers Thiel was faced with the problem of both wanting a “flat” midrange driver -which loses the advantage of geometric stiffness from a conical design - which would nonetheless be strong enough to be driven over a wide bandwidth. He ended up with a corrugated “flat” driver. I believe he said it was so strong it could actually measure flat up to 20 K! (I understand that the motor drives a larger portion of the driver than usual to avoid flexing) .

While some people prefer not to discuss the transfer of vibrations from the "voice" coil, it seems that Thiel was indeed considering this aspect. Observing the woofer (with the wavy membrane), it is evident that the vibrations were genuinely taken into account, rather than merely the "pistonic" motion. In the case of the round corrugated foil (membrane) in the driver, the pistonic motion was not considered at all. (I've been keeping an eye on the other group conducting quite successful experiments using simple aluminium food containers, both corrugated and otherwise, as driver membranes, full range, and as tweeters.)

Good luck, I wish you rapid progress on your journey

Good luck,

You too!

Also, would be nice to see that Reckhorn on the Klippel.

The Reckhorn drivers are often interesting and refreshingly different designs but in the end their budget can be seen in the measurements where someone shouldn't expect perfection, exemplary.

Back in 2019, PS Audio actually produced a nice looking loudspeaker.

I wonder what happened to it?

Nice!
Simple old-fashioned speaker box.

Simple old-fashioned speaker box.

Only the outside.
The speaker chassis, the horn geometry and the crossover are state of the art.

However, I would have chosen at least two 12-inch or one 15-inch woofer given the performance of the mid-high range.

For $45k it's certainly disappointing.
The Everest has 2 x 15-inch.
