Repair for speaker cabinet

@asvjerry yes my heart sank when I heard the bang and saw the Siamese kitty flying out the room! It’s my daughter’s cat and she feels horrible about it too. If only it would have went a little farther out it would have hit a pretty dense mat that is under the peloton and maybe did minimal dent or something. But it is what it is! That’s cool about the Tabby. My daughter loves cats and would like to see it.

thanks for all the feedback. It helps and as always gives perspective from others to gain knowledge 👍🏽👍🏽

Maybe I missed this but I would suggest bondo or similar epoxy wood filler, followed by meticulous sanding, then wet sanding, then paint.  I would think an suto body repair shop could do all or part of this for you.  (you were planning on having the whole cabinet repainted and not just "touched up", right? Black gloss if a very unforgiving finish.)

Let us know how it turns out.

KEF’s service dept. might as well be bad AI. If anything is outside of their lane, they don’t have a clue! 
If you have an old school piano store in your area, maybe they can fix your R3 or give you a lead on who can.

All the best.

@rayray57 from JayJay53, my advice is a combination of (1) live with it and (2) repair it enough so that you can live with it. 
Tier 1: Get out a black magic marker and hide the raw wood

Tier 2: Get some Plastic Wood or other wood putty on it, and either layer it up to size or oversize it before sanding smooth and either staining or painting to match

Tier 3: Considering the difficulty of matching a piano black finish, consider the putty + sanding repair before painting them a whole new color, like yellow for the patio, or pink for a bedroom, etc. This option will result in a whole new speaker in which the damage is well-hidden. (My grandfather was famous for eventually painting all his old furniture.)

Best of luck any way you choose to go. 
(Any professional repair will likely run you low three figures, in my opinion.)
