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 ?

I like a slight overlap of 10-15 hz. any where from 55-60 seems like a good starting point for the frequency of your speakers. Placement of the sub and of the speakers is critical. If your sub is in the corner then you'll have more bass but not the best bass. If the sub sounds boomy then pull it away from the corner. Also, and this is personal taste, find a song that you're familiar with on the bass and turn the sub volume down until it's not enough and then start turning it up until the bass notes are to your liking. I like my bass to be an enhancment to the mains instead of thundering and overpowering. But thats just me. Hope this helps. Zmanastronomy
Thanks very much. I see that if you roll the freq back, you sort of need to roll the volume up...
