Hi!
I just finished to polish my new speakers, since I havn't found a convincing guide I decided to post my experience.
The wood is Afromosia, from Paraguay, glued with PVA glue (Vinavil). First prepare the surface wih sand paper till 320 grit (all the steps from 80 grit), then apply a mix of 50% boiled linseed oil - turpentine. The first two hands plenty, I found pretty useful a jeans small rag, it doesn't shed hairs and helps polishing. The following coats with less oil and more rub, 30 min after each hand it's good to clean the surfaces from residue. With less oil applied the drying time is shorter. After the VII coat (half day rest) a light clean with jeans rag with turp.
To reach a nice high surface apply a mix of Carnauba and Beeswax by hand and remove with wool cloth. I found pretty convenient to use the polisher tool, not very traditional but effective.
I found this method accurate and good for the result. I tried in the past another method with no satisfaction: it used pure oil in the last coats, a messy work.

Final polishing with power tool.
