Appreciate the recommendations. leather may be a good choice but I am familiar with veneering techniques and a Rosewood or straight grained teak might be just the ticket for these. I also thought about veneer that has a pronounced heartwood color that could be centered down the front bevels. We shall see. The foam surrounds are a full 203CM/8" so most aftermarkets wont work. Ordered originals which take a bit to receive.

I had a pair of the first run Diamantés with solid black bases and the dark green swirled uppers.  I liked the appearance of them.  I toured the factory in Colorado Springs and spoke with Roy prior to purchasing them.  The speakers have a  live sound and excellent reproduction of dynamics.  They were definitely not a warm sounding speaker in my setup.  More of a sit up and listen presentation than a sit back and relax.  
I used OCOS speaker cables with the snap connector ends which greatly simplified installing the uppers onto the bases.  Routing speaker cables through the bases and trying to pull back the excess cable whilst placing the uppers on the bases was a PIA for one person.

Amplification at the time was a Classe DR5 preamp and a pair of Classe DR8 amplifiers.

You might want to look to see if yours have some of the updates.  The first one, and one that made the most significant improvement was the addition of C channel aluminum braces which were bonded to the lower sides of the cabinet in the woofer section.  As I recall the braces were composed of two per side, four for each speaker and bonded with construction adhesive.  The instructions also stated to remove approximately 18 inches of the wool from the transmission line. I did the install myself.  Later on there was an upgraded crossover, Series 3? which mellowed the speaker.  I didn’t like the crossover upgrade and eventually sold the speakers.  I don’t recall how one would identify which crossover is which.

Good luck on your project.

How do you post a picture? I would like to share one of the finished drivers.

So for those willing to attempt a replacement of a surround; It wasn't bad. If you remove the dust cap you can shim the voice coil so it is centered. I would recommend practicing putting your glue on some scrap first and understanding its working time and any idiosyncrasies. The first speaker the glue tube had some gel in the top and made a bit of a mess. Took some effort to clean it off. Some videos suggest using a brush to spread it evenly on the surround- I found my finger was far superior to avoid mess. Overall, the Eton mid- ranges tuned out pretty great. Still awaiting the ScanSpeak surrounds.   

@ovinewar1 ,

Any updates on the speakers?
