Low-pass setting

Is it customary to set low-pass to a sub at -3 dB or - 6 dB of a speaker response curve, e.g., 80 Hz or 45 Hz for a KEF LS50? What about high-pass in relation to low-pass?

I suppose it might be possible to use a SMS-1 with a KEF KC62.

There is a gradual roll-off just above then a sharp drop-off just below 30 Hz. That leads me to expect KEF's specs for average in-room response for the LS50 may be pretty representative.
