Maybe I will create a passive crossover network in the next time for this loudspeaker, but only for the upper two rails (midrange and tweeter) for using a tube amp or single ended amplifier like a ZEN.
The most easy task is the adjustable active low pass for the bass - here I will use a good car hifi version like the syrincs subcontrol II - go to post #5 about

More difficult is the appropriate choice for the cut-off frequencies.
Maybe one of the members has performed this already.
Thanks for any hints and reporting of already present experiences in order to several different tweeter models, which are released over the time of manufacturing of the Keltik.

there is to find a schematic of the Keilidh schematic for crossover network, maybe this is suited, so that only an additional high pass is necessary.

Unfortunately the Owner's Manual under
ftp://ftp.linn.co.uk/Manual/KELTIK_KELTIKAKTIV_(E).pdf
don't provide the detailed schematic of the active Sallen-Key stages. Who can upload this?

I'm also very interested as I have a passive keilidh crossover that failed, I haven't pulled it out yet. I would like to find someone that has upgraded the components and can advise me because I'm a novice. Thanks
Same here, I have another question: i cannot find a 14mf capacitor, is it better to choose a 15mf one or combine 2 in parallel to get 13,8mf?
What would be the effect of both?
Thanks!
