That's a heck of a system. Plus, I'm truly happy to see that you appreciate the history of your speakers, and that you want to preserve and protect them. Bravo.
Also, is there any chance of you providing any specifications? I see what looks like a JVC ribbon tweeter, the 3 Strathearn ribbons, 2 different style mid-bass woofers, and 2 lower woofers. Do you know the size of the various woofers? Any reason for the 2 style of mid-woofers? BTW, the woven mid-woofers look like the same drivers that Brian used in RM-1's. Plus, MCM Electronics used to sell those. They still sell a very similar cast frame carbon fiber woofer.
Oh yea, there's a guy in Tennessee that sells DIY speakers, using Strathearn ribbons, on eBay. He says he imported the ribbons at one time. Dr. Marks uses Strathearn Emits and ribbons, matched to Magnepan bass panels. They're a bit ugly, but I'd love to hear them.
Thanks for the dedicated thread, even though you were fine posting in my sales thread. Please feel free to update. I look forward to more info!
