Crossover settings

[03sonic]

Here is what I have wondering what settings.

Polk RTIA9 fronts
CSA6 center
FXIA6 rears
SVS PB12 plus
Xpa 1 (2 of them one per front speaker)
Xpa 5 for the center and rears
Sherbourn pre receiver

I read select the fronts to small, what is the best crossover settings for this set up. A base line would help fellas.

I kinda like Booms suggestive setting. Take the roll off and double it. Let's say your speaker rolls off at 35hz then set the crossover at 70. Tweak with your ears

The RTi A9 towers have bass response to 30 Hz.
The CSi A6 center has bass response to 45 Hz.
The FXi A6 surrounds have bass response to 45 Hz.

The "rule of thumb" is 2x the LF response of the least bassy of the speakers driven.

Therefore, 45 x 2 = 90 Hz.

But this is a loose rule, so anything from 80 Hz. to 100 Hz. should work just fine. Since 80 Hz. is the THX spec, I'd go with that were I you.

Okay so I am a little confused Set them all at 80 to 100 Hz? also what about the Sub? Thank you

I'm running the RTi A9s in my theater and have played around with x-over settings a bunch.

In a nutshell it depends on what YOU like combined with how they "work" in your room.

Movies:
I set them at 80 Hz but I also have a very strong sub that can fill in the "gap"

Music:
I set them at 50 and pull back on the subs gain a bit.

The RTi A9s can really dig down for the bass and the multiple drivers really take the strain off the mid range.
