One nifty thing about Classic Klipsch products that came with the WO (walnut oiled) finish is that if you take boiled linseed oil and 0000 steel, (remove grll cloth and put speaker on a drop cloth of course)
1. put a generous amount of linseed oil on the wood,
2. polish the wood with the steel wool (with the grain),
3. take a clean cloth and wipe off the dirt that has accumulated in the pores of the wood, the aged wood, the broken down steel wool and the dirty linseed oil,
4. repeat above three steps 2 or 3 times
5. apply linseed oil and buff out with a clean cloth
6. repeat #5 until the cloth comes out clean
You will get a spectacular finish on the wood that looks like the grain is a mile deep.
Re-oil with boiled linseed oil once a year or so to keep dust out of the pores.
