Crossover for 705

[Zohar]

I got the front B&W’s 705 loudspeakers :T connected to my Rotel RSX-1056, in the receiver set up menu there is a program for speakers crossover which has a setup default of 100Hz.
What should be the crossover setup for the 705 loudspeakers (I got a 12" Sub woofer )?

Zohar,

A good guide is to set the crossover at a point a little above the speakers own natural frequency drop off so you don't get a double cut in volume happening causing a dip in response. For the B&W 705s this drop off starts at about 60Hz so an 80 Hz crossover would be perfect. Luckily this is also the recomended THX crossover point for the LFe channel etc that most movies are mastered to - so you get a double bonus.... :)

Enjoy your speakers and don't forget to use a Sound Pressure Level meter if you can get hold of one to calibrate the levels for the speaker and the sub. :)
