Some Beovox RL 60.2 and RL 140 came home with me picking up a project Beocenter 9000 and of course the RL 140 foam surrounds had deteriorated after sitting in the sun for the past 25 years.

There is a great speaker shop close to a discounted liquor store in town so I grabbed some foam surrounds, dust caps, shims, glue, and Campari and gin Wink.

Gently pried off the paper outer rim and started scraping

Nice and clean after very thorough scraping of the surrounds and gently scraping any remains of foam from the outer come. Then I cleaned the metal outer with a little alcohol and my esophagus with a little Campari.

Then comes slitting the dust cap.

Placed the shims to keep the voice coil from rubbing.

And applied a thin layer of glue following the marks where the foam had been.

And to the foam surround and let the set for 10min until the were tacky.

Gently applied the foam and placed the outer ring over to assess they were centered. Having good quality foam made it easy since I mostly used the previous foam line on the cone as my reference point.

Then I applied glue to the under side of the outer foam edge and to the metal and underside of the cardboard outer rim and the upper edge of the outer foam and gently pressed together and assessed for a symmetrical placement. Then I flipped it face down to dry.

After

Dust cap. Easy.

Many, many screws later I caught a Pokemon.

And tested with some old Kanye

Happy ending, and a big Negroni.

Nice to see another excellent refoaming job. I miss our regular "to shim or not to shim" debates of yesteryear.

I wasn't here in yesteryear. $5 extra for the shims and dust caps seemed like a safe choice for a noob like me.

Is there suppose to be a boutique film vs regular electrolytic speaker capacitor replacement debate now? I wasn't here for those conversations either. And wire choice!

The debate wasn't electrolytic vs film, it was to recap or not to recap.

When I went to recap my Beovox 5700 I found one of the mid range drivers had the wires reversed. Fixing that made a big difference. The caps, not much. I can see why there might be debate.

To refoam or not to refoam, not as much of a debate.
