Ohm Walsh F Hope of Resurrection

Now I have F's with rotten surrounds, but rest look nice, perfect even. Cones, spiders look great. 

One surround is done, decimated.  Other is intact, perhaps replacement as is not identical. 

Perhaps I try replacing surround? 
Any new and improved surround options? Willing to replace/ get repaired more, if necessary.  

Cursory search doesn't reveal any drop in replacement.  Or, am I wrong? I see the Ohm return/upgrade to newer version options. 

Experienced and insider opinions sought. I'm not cheap, and I'll spend the money to obtain the exceptional if needed. So, what are the likely and less likely options   TIA
What is that one "clone", HHR? Need to check...  i heard it at a show years ago.

dgarretson, yes, I recall meeting you at Axpona, a very pleasant experience! Yes, Dale puts up a very nice speaker, no doubt. 

I appreciate the lead on the treatments for the cabinet! The epoxy/sawdust fix sounds like a winner!

Time moves Oh, so s.l.o.w.l.y. when waiting for a repair!  ;)

Repair now underway. It seems one driver is original and the other not. The original does not have ferrofluid, as it had not been invented at the time. A different lubricant, such as a grease, was used. At some point one driver failed and was replaced, the new unit utilizing ferrofluid.

The drivers are having spiders and surrounds rebuilt, the one with hardened/tacky ferrofluid has been cleaned, and both will be reconditioned with new ferrofluid. My understanding was that the original units were prone to failure, but the addition of ferrofluid ameliorated that problem. 

I may have reconditioned Ohm Walsh Model F’s for Christmas! That would be fun! :)

22 hours of driving, 1,370 miles, and total for project, including travel costs, of $400. DONE! 

Speakers are warming up (slightly; they were in car cabin, of course), and will be assembled tonight. Perhaps a first run this evening, too. We'll see. The hard work is over, now it's RELAX TIME!  :)

Now for the vintage Ohm community, a question; I have heard the joke re: 200/300 wpc wakes them up, and 301wpc blows them up. Ok. I have a super-clean class D that puts out 600wpc into 8 ohms and 1KWatt into 4 Ohms. Is this inherently a problem for these speakers, or only� relatively a problem, i.e. temptation to play them too aggressively? I see mapman is using plenty of clean power.
