Reminds me of a pair of Paradigm Studio 10 that I bought new. I was so excited as they were my first pair of “nicer” speakers. I had only had the Monitor Series up until that point and the Studio’s were a step up. Just beautiful little speakers. I was being so careful with them while setting them up but somehow managed to indent one of the tweeters domes. Man, I was so pissed off, lol.
As to the original Post, I personally repaired some KEF Xq5’s. They had been knocked over and had a corner busted out. It was a curved surface with a crease line as well. I just sanded it down, and then built it back up with some putty (wasn’t bondo but similar. Mix 2 pastes together then apply, sort of thing.
I ended up sanding down both speakers, then painted on 3 coats of primer and then 5 coats of black followed by 3 coats of clear. I ended up sanding all the way through the clear so next time, I’d by pass clear and just lay the color on really thick. Then spend the next week sanding and polishing.
It was a fun project but the bedr part was showing them off to my brother whom I bought the kefs from. He was blown away at how they turned out.
They came out with a mirror finish and zero orange peel. Quite ghe fun little project but quite time consuming. The next pair I do will be smaller speakers!
