KLH Model Six Speaker Restoration.

[morris 390]

The first speakers I ever had were KLH model 6. A gift from my parents when I graduated from high school. 

They have been in the closet for years because other speakers I've acquired sound better. I found that many people have been restoring them and the good sound comes back.

 

Acoustic suspension speakers are supposed to be air tight. The cloth surrounds dry out and leak air.

ebay seller vintage-ar has a sealant made for restoring the cloth surround. In hindsight, I should have applied the sealant las as it stays tacky and collects dust and fiberglass while working on the crossovers.

Here is the stock crossover after removing the woofer and half the fiberglass stuffing.

 

I replaced the crossover caps with Daytons from Parts Express. 2 2uF and 1 8uF for each.

The new caps are installed. They are glued in with Amazing Goop.

I replaced the woofer gasket with some rope caulk to insure an airtight seal.

Reminds me of when I rebuilt my Genesis Physics II's. Fun times!

The refurb is complete and the speakers sound great. Much improved.

Now I need to see what I can do to fix all the scratches like the one seen here on top.

I used this on my Genesis II's. Excellent results!

And these Minwax Stain Pens first for the touch-up...
