Can anyone help me work out which Falcon Acoustics Cambridge R50 Crossover is right for me?

My Cambridge R50 speakers have the KEF B139B, KEF B110A, KEF T27 and Coles 4001G setup.

I see Falcon have a No.6 and a No.33M (super power) version but there seem to be a variety of No.33’s and other options as well. I am looking at the fully assembled sets.

Am I right that it really just comes down to the normal power No.6 and the higher power No.33m or are there other options hidden in there.

My R50’s have the sticker on the back that says 50w rather than the standard 25w.

Any experience of these crossover upgrades out there? Thanks.

Hi paulsaints - harking back to your R50 capacitor thread early this year....

I assume that you have decided that buying a fully assembled replacement xover would be easier than troubleshooting your old one/s?

You are correct in looking at the 2 versions of Coles 4001G tweeter xover.
Falcon have been around for a long time, so I would question them & discuss with them.

Alternatively, if you feel up to the soldering/desoldering, I would replace all the capacitors(7 of them) & the resistor(1) & you should be good to go again - the chokes/inductors are likely still good.

(I recently heard a pair of R50s going at a pal's, they still look very 'modern' - see below...)
