I have had for 35+ years two E-110 and two M12-8 in .6 sf sealed boxes and they have been the best sounding mid range Piano speakers I have ever had. They have been in my attic awaiting re-coning for 10 years. and apparently that is about 12 years past the expiration of available factory kits. I can't find any references for the M12-8 (not M112) except one line in a resource I found here that shows them to use the same kit as the E-110s which makes sense because they are Identical baskets to the eye. Now I see that there may be a glimmer of hope I can get the C8R2123H kits. or equivalent. Can anyone point me to a reliable and quality source you have got these from Or perhaps someone has 4 they need to sell. I really miss the hard hitting snap these provide. I can't get that kind of energy out of my Kappa6 and the 10W1-8s I replaced them with after they started making noise Just never had the crisp sound that the paper surrounds did.
any help or suggestions would be welcome.
