I am building as pair of fullrange speaers, I want to limit as much bass to them as possible.
If I built two subs (one under each speaker) and fed them a mono signal how high can I go with the crossover.
If I was sending a stereo signal I am sure I could go as high as the subs will play but with a mono signal I am unsure. |

I'm a little confused as to what you want to do. Are you asking how high up in frequency a sub can play before you can hear where it is coming from?

mwmkravchenko,
i think thats exactly what he's asking.
ive heard that around 100hz - 120hz is where it starts being directional. |

I would say around 80 hz for this reason.
If that is your X-over point it is the beginning of the decline in the high end of the sub-woofer. It will only be attenuated by the slope that you have provided. Typically the slope is 2nd ordr or 12 db/octave. That means that at 160 hz it will be roughly half as loud as at the X-over point, and at 320 hz it will be 1/4 as loud. Ideally you would want a fourth order slope or 24 db/ octave . That would put it 1/4 as loud at 160 hz. This is enough to be an effective low end to high end crossover.
