Depends on the sound that yiou like. If you like big, booming bass you could set your LPF for the sub at say 100. Most people have it at 80hz.

If on the other hand you like tight & crisp sound, you can try cutting them off at 50-63hz.

Best to let your ears decide.

General rule of thumb, your LPF on the sub should be the same as the HPF on your fronts. This way speakers recieve the frequencies they are best equiped to handle. Also crossing LPF and HPF at the same frequency ensures there are no holes in the sound. (frequencies that are being missed by the speakers).

You set the subsonic filter to the tuning frequency of the box, which is usually in the 30-45Hz range.
