Merely a matter of developing the right theory for simulations - after that, none of it needs to be empirical.
And when the hell did he say that?

Its a Cadence 12" car sub, I dont think its a phase plug just a bullet shaped dust cap if you look closely it has air holes in it(the black dots...)Paradise_Ice said:
i see, I company called Volt made this Exoskeleton radial drive, it was very impressive indeed, never did hear one but Wilmslow Audio rave about them! The heat is draw up through the pole yoke into the chassis fins, That also had a phase plug i remember.
Anybody know the working of that driver at all?

The Deckware Tweek!
Ha ha ha. I just had to try it. I pulled the wooden phase plugs out of the FE107E's. I then pilfered from the company tool box two 9/16" sockets, which fit perfectly. Hey, they sound just fine. I'm not sure whether I'll be able to get them out or not. They really slammed in there, I'm here to tell you.

Re: The Deckware Tweek!
how do they sound vs. the wood plugs and vs. no plugs at all?
i'm contemplating trying this mod. on my (damar'd) Fe166E one of these days.

Hi
this is the best - i found here an easy reading to the technicality behind - phase plug
if any one need s a more detailed specific reply as to designing of phase plug and application - materials to use ets , please let us know - how to couple horns , radial phase plugs etc

Plugs are definitely better than no plugs.
My first impression is that the metal may sound better than the wood (with metal screws). But I have not done a double blind or even a fast A/B. (It's hard to get those sockets out of there!) I *think* I may hear a reduction in high frequency raspiness. But we're talking very small differences now. At least the metal sockets didn't mess up the sound in any obvious way.

Socket 2 me
I set up an A/B test for the wood plugs and the metal plugs (socket wrench sockets) . I've decided I cannot tell the difference. I also cannot tell the difference betwee Husky and Craftsman sockets. 🙂
So the bottom line is that plugs definitely improved the sound of a couple of dammar-treated FE107E's, but it would take an ear more golden than mine to tell the difference between a metal socket and a wooden plug with a couple of metal screws in it.
The biggest difference seems to be how firmly they attach. I have to use pliars to remove the metal sockets.

There is a lot less metal in the wooden ones.
