Took a Heresy speaker to get "repaired" in Upstate NY. They claimed, it's the tweeter. I then specifically ask for a repair not replacement. They said they can do it, so I agreed. They charged me 150.00. I came back in 2weeks, pick up the speaker, got home and put it thru the paces. It was like night and day!! The repair failed miserably. So, I opened the back up to assess the work! They took my original Vintage K-77 Tweeter and switched it out with a replacement Klipsch tweeter. I was livid!! Went back, made them track down my vintage k-77, which they complied. SMH... So how can I get both of the K-77 Vintage Tweeters worked on to maintain that sound or is it impossible...

Can the vintage K-77 tweeters be repaired?????

Can anybody repair the original K-77 Tweeters
