I use Menzerna products. https://www.autogeek.net/menzerna-of-germany.html.
The Focals are finished with an acrylic lacquer. These polish out just like automotive finishes but they are a bit softer so you do not want to use anything to aggressive. Menzerna's 2500 will work fine. Use a microfiber cloth. Flip the speaker so the surface you are working on is horizontal, squirt some 2500 on the surface, about tablespoon and polish firmly and briskly with parallel stokes in the direction of the grain. Then buff off with a clean microfiber cloth. Repeat until the swirl marks are gone. If you can feel the scratch with a finger nail this will not be aggressive enough. You would have to use Menzerna's 1000 on a random orbital polisher or better yet. Wet sand with 1200 grit silicon carbide paper moving to 2000 grit paper then the Menzerna 2500. For wet sanding use a quick detailer.
One important note. This is assuming the speaker has a gloss finish. If the speaker has a satin finish rubbing it out like this will convert it to a gloss finish! A stain finish you would wet sand out the scratches and spray another coat of satin lacquer. Which is easy to do....if you have the equipment and a downdraft booth. I never use satin lacquer for this reason. It is too hard to refinish. If I want a satin look I use gloss lacquer and rub it out with the grain with 4-0 steel wool. You can fix minor scratches just by rubbing it back out with steel wool. You could do this with the Focals if you liked the look.
