More information. The Kef Coda crossover was SP1035 (DN13)
It has 2 caps, and 2 coils.
The Coda was a bit bigger than the LS3/5a, about 7 litres.

Yes, thanks, specs are here KEF - Cadenza, Chorale, Coda, Cantor - United States.
What do you think to just removing the high pass section for the midrange in the Concerto's crossover?

I think it will lack bafflestep... 1.5mH and 5uF (or 4.7uF) might be closer.
The Early Cresta and Coda looked like this:
The Cresta had a very simple (guesses, 0.8mH?) bass coil, 4uF (3.9uF) and probably about 0.25mH tweeter coil. Probably positive polarity..

I spent a bit more time on this, and my rusty memory refreshed...issue being you have the early B110 SP1003. 🙂
The First two pictures show a KEF DN13 SP1017 crossover that might work for you. The coil in the notch has a resistance of 6.4R, which you could adjust by adding resistance to another type of coil.

The DN13 SP1035 had a 5uF tweeter capacitor and a tweeter coil probably around 0.2mH.
Larger bass coil, maybe 1 to 1.2mH and a definite 6uF. Positive polarity.

You seem to have a few options!
