Thanks for the input but yes, I swapped the tweeter from one cab to another and the issues stays with the cabinet/crossover. I am thinking that the cheap capacitor I bought just wasn't up to snuff. I ordered a more expensive one (the original and replacement were both rated for 100v, the new one is rated up to 250v and has tighter specs). The trade up costs way more than my original pair was and is currently out of my budget. The new caps are due to be delivered today. Hopefully it gets me another 17 years out of these speakers.
You really think the M3v are better than M80v2? That seems like an apples and oranges comparison.
