Setting Sub Crossover Freq


I have speakers that have rated sensitivity of 89-90dB
and a frequency range of 45-22000/50000Hz.

Anyone have any suggestions where to set a sub crossover frequency given these specs ?

Not neccesarily. What happens is that the frequency changes to a lower and less used freq. Once the music hits the lower freq it will still have the same volume just a lower freq responce. Play around with it and you'll get it just to your liking. It takes time, several weeks or more to tune a system in. Aiming the mains is very critical for stage and imaging. Tweek and listen for a while and tweek somemore and when you get something you don't like just go back to were you had it before.
If you get and use a copy of RoomEQ Wizard so that you can measure what the speaker(s) are actually doing in the room, setting crossover frequency, slope and levels is pretty easy. It may also give you an insight into better positioning of the speakers/subs.

Doing it by ear is hit-or-miss unless you have a lot of experience in this endeavor.
