How Science Got Sound Wrong

" Looked it up, pretty neat stuff. Trying to get a better impedance match on the air vs the throat and dome?

machining the throat/horn is a bit of a bear, I’ll wager. that’s some painful bit of CNC work, probably with some notable finishing work. (I bought a 5 axis CNC set up a while back)"
It is a migration from the older tweeters used by Klipsch in many Heritage speakers to a modern tractix curve inside the lens cavity. Also meant to allow for mounting more than one type of driver if you choose to experiment. The best drivers so far keeping costs contained to reasonable levels have been the B&C DE10 and DE120.

Don’t know how to answer your impedence match comment but this was tested with TrueRTA and REW to curve much better than existing Klipsch Vintage tweeters and so far measures very well against anything else offered to fit as an OEM replacement for K-77 and K-76,79,792etc too.
Machining is a breeze just using HSM and a ,007 step over with a .5" .09" corner round bull nose end mill. Stickout is 1.625 inches flute length so plenty of reach to cut it all. Modeled in Solid Edge and cut on a Haas VF4. There is no hand finishing required inside the cavity. I do buff the top with scotchbrite as I think it looks better that way.

Learning how to model this kind of part was the big problem.

Well, any finishing/programming issues would obviously show up in the metal more than the wood and I don’t really see any, so it appears to be a nice combination of quality hardware and well reasoned programming. To my relatively untrained eye, that is. (you edited to offer the buffing comment)

I mean, that Haas hardware... is enough to get an enthusiast all wiggly inside like a happy puppy.

Enough of the side discussion, I guess.... and back to whacking each together with nail riddled 2x4's of poorly thought out hack attacks.

  Ended up having to buff the top only because the engraving left a bit of roughness to the edges for one and I like the satin look it gives as a contrast to the shiny cavity.

Arguably rarely right. The naysayer is almost always wrong. Sometimes they are right, and they end up with a Nobel prize, not selling a "Teleportation Tweak" to gullible customers.

Is Teleportation Tweak considered a "thing" or it is some other state of non-being?

The problem for the naysayers is that the science and the physics has always supported what he is doing and what he is saying. It has no method of disproving him -- rather the opposite, in fact.

>>>>That’s a commendable question. Personally I’m not sure what it should be considered. But I know it’s both the lightest audiophile tweak AND the only audiophile tweak that doesn’t involve shipping or costs thereof. It also cannot be reversed, unlike phone calls. Yet, it is guaranteed. You don’t see that kind of customer support too much, I’m afraid.

Audiophile tweaks are like pudding. The proof is in the eating. No technical arguments or explanations are required. And if one is desired I have the definitive explanation of how the Teleportation Tweak works on my web site.
