Vinyl Junkie

Hello, new to community. I picked up a pair of speakers at an estate sale. They looked older, just grabbed them, unsure of what they were due to no badges or spec sheets. I have never owned a pair of Klipsch due to a little pricey for my budget. I have been doing research and I think they are 1980 Klipsch Heresy, S/N imprinted into the wood on the back top of the enclosure. #104U112 #104U113. Am I right about the year? I am going by looks of the speakers to identify. Enclosures have small nicks, scratches, grills are very good, have some fuzz areas on the cloth. I removed the backs that's when I found out they were Klipsch! Woofer is K-22-R, horn is a K-55-V, and tweeter is K-77-M Type E balancing network. I would like help in verifying what I think to be true. Thank you, going to enjoy these, as they sound excellent!
