Phileosophos...5.1/7.1 setup needs low frequency content pushed to the...Sub channel

PhileosophosI'm looking for the drivers to provide the proper crossover options so that it will work with all applications, games, etc.

Right.  A decent AVR will do that for you.  Used to be called "bass management".  I know some sound hardware comes with PC software to do that, but if you have an AVR that does, that's the better place to do it.
P.S.  have you given this a shot?

Proper speakers should have high pass or low pass filters built in which are appropriate for that speaker's design.

You're missing the point: by the time it gets to the speakers it's too late. The whole point of having a subwoofer is to take the heavy-lifting off all the other speakers. In order to do that, the low-frequency content must be sent to the subwoofer in the first place. That has to be done via a crossover at the driver level, because otherwise the low-frequency content goes to the individual channels, isn't on the CSub channel at all, and thus your subwoofer is essentially a useless lump, doing nothing.

And what audio does one find in the center channel of any 5.1/7.1 source? In most cases, nothing more than dialogue. And since dialogue doesn't really have stuff in the frequency range your subwoofer is designed to operate (typically <80 Hz.), the most you'll get is some plosive thumps.

Bumping is not allowed on this forum.
 
Based on what you said, you've demonstrated that you don't understand that "bass management" is an act of low pass and high pass filters, and that configuring your analog audio inputs and/or outputs is a trivial task.

If it is dialog that you are after, add more than just a subwoofer to the center channel.  Wire in a subwoofer in line with a low pass filter (if it doesn't already have one incorporated) AND wire in a mid-range speaker in line with a high pass filter (if it doesn't already have one incorporated) in parallel.

You're avoiding the question: Do you have a sound card? Is this post relevant to you?

I just wanted to review the information to make sure I wasn't misunderstanding anything and I really think you're on to something here. I have a 7.1 system, but 5 of the speakers aren't full-range speakers. You're saying I just need to get five powered subwoofers with line-level pass-through (probably a built-in low-pass filter) and run each of the 'small' speakers through their own sub instead of depending on the sound card mixing low frequencies to the one subwoofer typically dedicated to that task? That's genius. Why do people even have 7.1 or 7.2 when they could have 7.5 or even 7.8? The sky's the limit.

No one produces audio with low frequency ("subwoofer") audio on only one left or right, front or back audio channel. Everyone produces bass content as monotone which occupies the "center" channel. Therefore, there is no crossover needed, unless you feel that your speakers are not working properly, or you feel that the record producer knows less than you do.

Like I said, add filters if you insist. You can easily do it; no software needed. Plug into all of the audio outputs, perform whatever crossover you want, and then connect your speakers to that. But don't blame EVGA for failing to do some goofy audiophile niche thing. If EVGA wanted to chase the audiophile niche-thing rabbit hole, they would find no end.

No one who is respectable, produces stereophonic bass. Why? Because the human ear is not good at localizing low frequencies. It's monotone. It's on the center channel. It doesn't need to be directed from the left channel or the right channel to the center channel. It is already in the center channel.

The bass remaining on the individual left, right, front, and back channels is the bass content (likely mid-range content actually) that the record producer or artist wanted to be there. They had full control when they recorded it and released it. All the bass on the center channel is what they wanted. Not enough? Add an amplifier to your sub. Center channel bass frequency too high for your sub? Add a low-pass filter before your sub because the sub's manufacturer apparently forgot to.  And if your individual speakers can't handle the mid-range content due to some defect or design issue, add a high-pass filter to them.

When you make this request, you are making 2 statements:
1) My favorite artist and/or producer is dumber than me.
2) My speakers don't perform to my expectations, and I think it is my sound card's job to fix that.

Both seem a little absurd to me.

To everyone looking for bass management on the NU Audio Pro 7.1, there seems to be a very simple solution: Uninstall the NU Audio apps/drivers, and then reinstall but exclude Nahimic EQ when given the option. Nahimic apparently overrides other Windows audio enhancements. Without Nahimic EQ installed, the Bass Management option returned to the Sound Control Panel:
 
Of course, this also means that you lose EQ capabilities inside the NU Audio app. is an excellent alternative (and more powerful).
