in Vintage Speakers
I have a pair of Monitor 7s that I bought new in 1987. For the last few years they habe been used in a garage-like block building that I use as a workshop. I have not been very happy with them, but I figured, it's just my workshop, don't care that much.

I recently started reading this forum, just out of curiosity, and ran across the posts of people who recommended recapping the crossovers and replacing the tweeters with RD0194s. I assumed new tweeters would be the big improvement, but they were not in stock anywhere I looked. I decided to try the crossover recap, and got the Dayton caps from Parts Express.

Holy crap! I am blown away. This is not a subtle change. Everything is rich and clear, Bass is clean, trebles are bright. Completely different pair of speakers.

Midwest speaker repair just got RD0194s back in stock, so I ordered a couple. I can hardly wait to hear them.

    Nice work! Sound "good as new"? "Better than new"?

    I'm afraid that my memory is good enough to remember what they sounded like new.

    Capacitor upgrades are a must for most vintage speakers in my opinion. Great job.

    And upgraded the resistor. Dayton is not a good choice for the 12uF either.

    Works for me, lol. Of course, now I'm down the upgrade rabbit hole, so I am willing to entertain all suggestions. Spent the last couple hours researching "magnet shift" and I guess I have more work to do.
    Thanks!
