Here are some pics of my new to me Khorns that I was looking for date information on. Thank you for helping me identify them.
I acquired these locally a few days ago. The seller also included new pairs of Klipsch woofers, tweeters and crossovers, which he bought from Klipsch a while ago. My understanding is that he purchased these parts from Klipsch because he thought with the speakers being so old the internals needed replaced. Once he replaced everything with the new internals, he couldn't hear a difference between the originals and the new, so he put the originals back in.
I'm currently renovating our detached garage and making it into a mancave which is where these Khorns will reside. They work and sound good to me. Any thoughts on the need for additional upgrades beyond what the original owner attempted to do?
