I was able to find and purchase a set of 2 Sunn model 4 m, 8 ohm, 100 watt continuous, speakers yesterday (in 48 inch tall boxes). Would any of you have any kind of paper on these? (schematics, production years, manuals, parts lists, etc.) So far they appear to be in very good shape, minus the few expected dings and tears on the cover materials. They look like they're going to clean up very nicely!
Any help is greatly appreciated. (I'm brand new on this site, so if I've committed any grievous errors, let me know gently. I'm old and retired.)
