I can't thank y'all enough for the information. I'm ordering the Advent woofers on Monday. I need to source tweeters. Is there anything recommend? I want to get them clean and operating to get a baseline for repairs to the crossovers. I also have to pick up a new fluke. My crapped ours after 30 years. Jon, I will focus on the components you suggested. Here's a picture of my progress with cleaning off the paint.
