Sorry, but that is not an adequate answer to the question "why". I must also say that it suggests a lack of understanding of the relationships among receivers, subs, and speakers when it comes to bass management. When you say "this particular sub/receiver" combination, you are leaving out the most important component of all, the speakers. If the OP needs to set the Onkyo crossover at 120Hz or 100Hz because of his speakers, then an 80Hz filter at the sub creates a rather significant hole. But, unfortunately, you are unwilling to address that issue. It would be helpful to the OP if you were to explain your thinking here. We might all learn something.

You're world use, but not real world use

If you say so. I am so glad to know understand that you know all. But since I have evaluated and setup up about 10 of these systems in the last several months, I speak from experience...

No explanation necessary. I didn't post this for you to question it. If you don't like the suggestion it is noted. Too bad you fail to see beyond your blinders. I will not post a 3 page description of the relationship of this equipment and it's functions to satisfy you.

Let the OP do what they want. Go trash a thread somewhere else.

I never said I know all but you seem to think you do. I have read many of you're post in the past and you always have good advise and or information but I still have to disagree on the way you are telling the OP how to set his subs crossover up

There's one additional switch on your sub - the one that says LFE/Normal. Here's what p5 of the PS210 manual says about where to set that switch:
Quote:
If you have a Dolby® Digital or DTS® receiver/processor with a low-frequency effects (LFE) or subwoofer output: Set LFE/Normal switch to “LFE.”
p6 of manual then explains how that affects the Crossover Adjustment:
Quote:
NOTE: This control will have no effect if the LFE/Normal Selector ™ is set to LFE. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting.
Since you have an AVR with DD and DTS decoders and a SW output, Infinity recommends that you set the LFE/Normal switch to LFE. That disengages the crossover adjustment on the sub and lets the AVR handle bass management. The sub will then play whatever your processor sends it.

So, on the sub, you should set the volume around the middle, the selector switch to LFE, and the crossover level doesn't matter since it will be ignored based on the switch setting. On your AVR, set the crossovers based on what your speakers can handle. Speaker manuals usually contain that information.

Good post BIslander and correct. For someone who has tested this sub in the real world, so he says, has no clue on how to set this sub up or any sub for that matter. Makes me wonder his credibility on any feedback on any products since he wasn't even able to back up his so called research when he was called out on it. Buy the way if you need any medical assistance I am a doctor

That is certainly one way to do it and a proper way as well but not the only way.

That's the response from a so called "industry professional (design/engineer)" Makes me wonder who is hiding behind the computer

After post #5, #7, #24, you finally admit this is the correct way I have only one question then, why all the disagreement

Actually, when bass management is performed by the processor in a multichannel system with a powered sub, I believe it IS the only proper way. From UltimateAV Magazine's primers on bass management:

http://www.ultimateavmag.com/howto/805bass/

Quote:
This brings us to subwoofers with multiple line-level inputs. The concept of a subwoofer with multiple inputs that have various filtering and summing functions makes no sense in light of our discussion of bass management. In a multichannel audio system with bass management, a subwoofer needs one input, a polarity switch, a power switch, and that's all folks! Those other things-diverse inputs with misleading names, a stereo summing input, a lowpass filter, a volume control, etc.-are only useful in a stereo system without bass management.
