Does anyone have Thiele/Small parameters for the Penta midranges?
I'm investigating putting together a recone kit for these for a small project.
The drivers are most likely produced to B&Os specs and I don't think, the T/S parameters are publicly available.There are ways to measure them, though, but a bit expensive and quite elaborate.

The easiest way to do TS measurement is with this:

Costs a bit under 100 dollars US, and I can measure a driver in about 5 min. As opposed to the hours it used to take me with a signal generator, DVM, etc.
PI can highly recommend it, works great for doing impedance plots for a whole spkr from 20-20,000 hz.

I'm afraid I'm recovering from the BeoVirus.
Jeff, what an awesome bit of kit. Failing a few leads I'm going to give this a try. Many thanks.
