How To Fix (Almost) Any Set of Audio Speakers 3

Feb 19, 2010

Are you ready to rock, Unplggd readers? Do you want to save your hard earned dolla bills? Welcome to the third and final week of our easy vintage (or just plain old) speaker resurrection. Be sure your paint brushes are at the ready...

Last week we talked about the rebuild process in re-surrounding your woofer with a Parts Express Speaker Surround Repair Kit. We got the woofer reattached and added back the new dustcap after pulling out the shims.

What You Need


Here is everything that comes in the kit. And for icing:


1. This is really about reassembly, so the tutorial is simple. First of all, make sure you don't leave your speakers out in the sun. We left ours in a window sill over the weekend and when we came back, some of the glue where the outer part of the surround meets the metal gasket had come loose. BAD.

2. Next... make sure you align any gaskets that go between the woofer and the speaker box and if you have a bezel like we did for these Bose 301s, don't forget to put it back on. The bezel actually served to compress our foam surround back to the metal frame so that the problem we had above is solved.

3. From here on out it is about decoration/restoration. We decided on a nice red finish to confound the next owners of these speakers in the future. At least it's not cesspool green. Fill any holes that may have been made in the cabinets. Ours had what appeared to be mounting bracket holes drilled into them. A little wood filler and a quick pass with some 150 grit sandpaper and these holes were brought flush.

4. It is a good idea[r] to sand the whole thing so that there is some tooth for the paint to grab. We opted to not paint the inner black areas of the boxes so there was a lot less work to do. The contrast will be nice.

5. Wipe them down with some cheesecloth or just some paper towels if you don't want to be anal about it and start priming. We did a little masking to protect the business areas of the speaker from overspray- this may not be necessary for you. We had a couple different colors of paint on the cabinets so we decided to paint the green areas white. This insured that the final finish would look the same all over.

6. We had some "Colonial Red" paint in a can that wasn't busy and while it wasn't the final color we wanted, it gave us a nice base upon which to spray our final "Monkey Butt Red". We applied it with a really awful brush we had lying around so the strokes are highly visible. This is just part of the fun; no need to be super perfect about it. Then just spray the final coat.

So there you have it: ressurected speakers. We didn't have the grills for these but whatevz. The sound is back to its original tightness- the bass! Where did that come from?!?! Really amazing to see the )

Don't be afraid to do this yourself, the kits are $25 or so which isn't cheap, but we brought back some $300 speakers so, in the end, it's a great value. If being green is important to you, you can't do much better than this. Imagine the kudos you will get when you explain to your friends how you saved these old beauties from certain landfillery.
