I've made up a mixture of bees wax and linseed oil before, but I've never used it on speaker cabinets. I did it for a vintage-ish commercial grade credenza that I purchased for my TV/audio cabinet. The results are mixed. It darkens the scratches a bit too dark, and it doesn't give much of a shine. It does look better then before, However. It could be that it isn't the best to use on whatever the original finish is........ maybe a lacquer?
