Just cut higher as they might play that frequency better than your 'full range' speaker
 
As I said, I don't want to play it above 120 Hz, is MORE THAN ENOUGH spl there.
 
I was asking about minimimum freq for cut off, type of filter BW or L-R, and slope db/oct.
 
Also for an known good bass shelving point.
 
Thank you.

They give there freq response, not optimal crossover points, bass shelving, etc.
 
Regarding those specs I decided to use BW filter with 30db/oct slope at 53Hz for low cut, and BW filter with 24db/oct at 120Hz fot high cut.
 
Any other opinions are welcomed, for low cut and bass shelving too.

depends a lot on your total volume/SPL required imo.
driver seems robust enough to take a beating. 500w p driver, hpf 18db bw 40-45hz, some eq to get desired response for the location, style played, upper x over to match your tops and prefered sound.. many people cut their bins way too high to get a smooth rolloff which imo forms the characteristics of bass sounds.
(for example 40hz dont need to be loud sometimes, hearing a 50hz bass rolloff naturaly down to 40hz sounds better than the same impulse beeing cut sharply above..)

I'm afraid to cut lower than 53Hz, afraid of overexcursion of the driver...

I would argue that the frequency response graph indicates pretty well where to put the crossover points.
