jon - the fiber is to increase impact and stress resistance and add some damping. It does not reduce shrinkage. Concrete is Portland Cement based, which shrinks. Gypsum cements expand. USG Hydrostone is a combination of the two and can be admixed with acrylic, etc. plasticizers to increase damping at the expense of lowering resonance frequency. Paul added some plasticizer. I chose to run straight but added two different fibers which serves to suppress resonance & increase stiffness. I like grown solutions, and used hemp and rice awn fibers, but most folks would choose polypropylene or glass, etc. USG has zero, expansive and contractive products. I suggest you look there. I investigated air entrainment in the baffle core for lower mass & higher resonance frequency. These were follow-on developments after the CS5 cast marble baffle, which worked well, but cost and weighed a lot.

All, is anyone here bidding on that 3.5 EQ? If not, I'll try to snag it for the lab. (Remember the idea of fully balanced EQ with better caps and resistors?)

Wow Tom, you've been around!

I thought the bass on my Hales T5s was excellent, but thought the bass of the CD6 even better (more dense, focused, punchy) as well as the 3.7 and 2.7.

Tom,

Also...after the Hale Transcendence 8's Paul built a new interesting looking flagship speaker, the Alexandra (or Alexandria), which can be seen down the page in this old CES 99 report:

The few people who heard it absolutely raved about it.  But since it never went in to production due to Hales folding soon afterward, it became something of a unicorn. Did you ever hear it?

I finally got around to measuring my room/speaker interactions on my Thiel 2.4s using REW and uploading a convolution filter to roon.  ITS AMAZING!  TIGHTENING UP EVERYTHING.  Imaging if far superior now to what it was before.  Frighteningly good.  Suggest you try it.
