Set Crossover for CS10

rcpolk

My amplifier allows Center Channel speaker to be adjusted between 40Hz-200Hz.
I need higher frequency to come out of that speaker.
Default setting is at 120Hz.
Should I set the crossover to 200Hz and type to Small?

I'd set it to 80hz myself. That means that every frequency above 80 hz is going to come out of the center.

What do you have your sub crossed over at?

I've found that the best generic XO settings are 80hz for the fronts, surrounds and center, with a 120hz XO point for the sub.

Thanks for reply.
Sub is around 120hz. Does it mean that the sub only plays above 120hz? What about sounds under 120hz?
Have just set the others to 80hz.
I going to look for a movie with low dialogs and try it out.

That means that the sub only plays under 120hz.

The AVR applies a HPF(high pass filter) to the front/center/surround speakers...so that only frequencies above the XO will come through...and it applies a LPF(low pass filter) to the sub, which only lets frequencies below the XO point come through.


You may have to play around with the settings a little bit, but 80hz all around, with 120hz on the sub is a good general starting point. With the XO's set like that, your speakers will be carrying all of the information above 80 hz, and the sub will be carrying everything below 120hz. Notice that both the speakers and the sub are carrying the information between 80-120hz. I've found that an overlap like that helps, due to the natural rolloffs that the XO's will have. The XO's in AVR's generally aren't a brick wall type of filter...there is still information over the XO points that will bleed through. Overlapping the XO points like that, can help create a more natural blend between the subs and mains. You may have to tweak the XO's a little bit to suit your specific case though. Just play around with different settings and see what works best.

The important thing to remember, is not to set the XO's of your speakers higher than the XO of your sub. Otherwise, there will be information between the XO points that is lost.

Thank you. thank you.
Your explanation has finally made understand how the xo filters work.
Setting the XO as you suggested makes a big desirable difference to the dialog.
