6db is what you want to use as the 3db point will give you a hump at the crossover point. If you can highpass (cut the highs to the mains) then 80hz would probably sound better as the “bass” drivers in the Kefs are tiny and will need to travel pretty far to make a lot of output).
Keep in mind the 6db point is NOT where the specs are but where they measure 6db down in YOUR room.
60hz is a good safe starting point for most small speakers.
