Question Do you set the center channel crossover higher or lower?

Question: Do you set your center channel crossover at a higher or lower crossover than your left and right speaker?

My setup:
Front Left / Center / Front Right : Polk Owm5 (Freq Res 80Hz - 22,000)
Surround Left / Surround Right: Polk Owm5 (Freq Res 80Hz - 22,000)
Top Front Atmos / Top Rear Atmos: Polk Owm3 (Freq Res 100Hz - 22,000)
Subwoofer: SVS PB-1000
Receiver: Onkyo NR787

I currently have my front left/right speakers at 100Hz. My Center at 90Hz. My surrounds at 100Hz. And the Ceiling speakers at 120Hz. I ran the AccuEQ and it was way off (in my opinion). It set my fronts and center at 40Hz! So, I quickly readjusted using an SPL meter at the previously mentioned crossover settings. My fronts are 11-12ft from the listening position.

The reason for my question is... left/right/surrounds/ceiling speakers are essentially for background noise or effects in movies. So, should they have a different crossover than the center channel if it is the same speaker (Polk Owm5) ? Just wanting to get a pulse of the crowd. What is your setup like? This is of course for TV/Movies... not music.

Tell the receiver all speakers are "small". Set crossover to 80 HZ on all speakers.
All this means is that the bass below 80 HZ will be redirected to where it belongs, at the subwoofer.
You will not have a reduction in bass. I hope you don't think so.

No real answer. The quick answer is keep it the same if you have the same speakers up front but a lot is at play. The fact that the center is more in the middle of the room will give it a different response. I've been in rooms where the right speakers needed a higher crossover then the left as it was close to the wall and 80Hz had a large hump. Test, listen and repeat till it's done.

Onkyo doesn't allow the option of "small" or "large" setting for speakers. However, I can independently set the crossover.

I've read to always set the crossover 10Hz higher than the lowest freq. You would suggest setting them all at 80Hz? My Polk Owm3 ceiling mounted speakers only go down to 100Hz...

I think most people use the 80hz crossover point all around.

Okay, so if your speaker can reach down to 80 HZ, and you want to move that number to 90 HZ, it's fine...bass below 90 HZ will go to the sub. Don't be concerned that you will be taxing the speaker by letting it play down to 80 HZ.

As long as your subwoofer is near the front three 100 hz for the front three and 120hz for the Own3s is likely where I'd end up.

You don't want a "hole" where the small speakers drop off and the woofer kicks in.

These test tones can help ID that.
