I have been a big fan of Audio Concepts since they started. I have a catalog still from 1979 0r 80. They used Dynaudio drivers in some models. I would not give up on a ding. My favorite speakers the Dynaco-A25 Mark 2's had a ding. They had a beautiful walnut finish.
I sanded them down so they could except a primer, oil, it blocks tanin seeping thru the primer. 2 coats to make sure there is a thick enough coat to seal all. I used a wood filler from the hardware store. You use it like Bondo. Theres a little tube of activator to mix in with the filler and then you move fast because it drys like Bondo, quick. It's made by Minwax and is called Wood Filler, not plastic wood which sucks. There is a transparent top with the activator tube included on the can.
It may take a couple applications but with sandpaper and that primer you can make the ding disappear. Body work 101. The patch is solid and stays, my ding was the corner
So I lost my nice walnut finish but that doesn't make my speakers sound any different. It's just that (Monk) in all of us audio nuts that don't want to see that ding. I multicoated my speakers with a good black latex semi-gloss, the more coats the better looking. They look fantastic, but this is why I had to write.
I live in Maine and am a painter by trade. I have also worked in boat yards around here. Every spring a buddy of mine paint the hull of his lobster boat. On the top part above the waterline we used a special paint by Petit called EasyPoxy. It dries rock hard with a beautiful finish. It's what they use on exspensive sail boats over the fiberglass and dries with a jelcoat finish. They have a quart of black as well as other colors. This is the closest thing to a piano finish I have ever seen.
We paint his boat hull as a team. I roll it on and my friend feathers it out with a nice oil type brush. That technique is called feather and tic. Some old salt showed us how to do it and when it dries you will be amazed. With 2 coats I think you can be more proud of those speakers than ever before! I think the Easypoxy eliminates any need for clear coating.
Tonight I'll get my camera out and get you a couple pics. I also redid my grills with black burlap from JoAnns fabrics...very acoustically transparent. Don't give up the ship, remember American Restoration that show with Rick and son......take care Mark Korda..(firstname.lastname@example.org(https://www.wholesalemarine.com/pettit-easypoxy-high-gloss-topside-marine-paint-82251.html?gdffi=facc80a89aaa41289ca25f0e582c289c&gdfms=C1723CD9F9FD48D8A9741E5BEEE3BB4A
