Hi,

a few years ago I tweaked my father's KEF Concerto's : other wires, Falcon Acoustic crossovers (6c), modern banana plug connectors. But they do not sound "crystal clear" as my Castle Harley S2's. Any idea how I could improve this?

Concertos, as was the fashion at the time, were a bit "middly". Try a 2.2, 3.3 or 4.7 Ohm 5W resistor in between the XO and the B110.

What is the logic behind the power of the resistor ? Why would it not be beefier given the rating of the speakers ? Not arguing.. Curious.

The peak to mean ratio of real programme material is never less than ~10dB plus you are only working over a fraction of the audio band. If you listen to over-compressed noise well past clipping for long periods of time, then you might have to use a bigger resistor
