So the routing with two speakers or stereo should look like this?
An externally hosted image should be here but it was not working when we last tested it.
With more than 2 channels it's complicated even if an AVR is capable of routing bass to speakers and sub at the same time. There will be signals for which the whole thing is not calibrated for, e.g. LFE played back by the subs but not by the mains.
To avoid this you'll need an AVR that is capable of feeding the low frequencies of all channels to the sub out and back to all speakers—the LFE would need to be routed to every speaker too.
Implementation would be much easier if your code could work with fixed HP filtered speakers. Then nearly every AVR could be used.

That routing is basically correct, although one could just as easily take the L&R out of the DCX unit, but I know that audiophiles have issues with that. What you show is what I do.
It is my understanding (from an alternate site) that ALL AVRs will put the LFE onto any channel that is listed as "large" if the "No Sub" option is set. It's a standard function of the chips. This then covers 90% of the problems and if there is no unique center channel bass then all the bases are covered.

Please fill in where I went off track on this. I feel like I am missing something in this discussion.
On the DCX, can't you set all of the output channels to the one input channel?
So wouldn't it just be the normal sub out channel, the ".1" going into the DCX? Then the DCX controller feeds sub amp the filtered signal?

But you can send the full stereo signal to two low/mid channels, and the same signal to two other channels where you sum it and filter it to whatever you want for your sub. IOW, the low freq content can be summed to a sub as well as be filtered to a set of two-channel outputs at the same time. Isn't that what you need?
Example: channels 1 & 2 have stereo low/mid at 20Hz-400Hz, channels 3 & 4 have summed sub at 20Hz-60Hz.

...which is the optimal solution. There are several other multichannel volume controls out there.
Nevertheless if you don't use the DCX's digital in (which is buggy and can only be used for 2 channel pcm audio—NOT multichannel streams), there will be an additional A/D/A conversion. I don't believe that this conversion is audible—just to get the whole picture.

I will stand by what I said before, The DCX works fine as long as the center channel does not have unique LF content, in which case, it won't be properly played. BUT, from what I can tell this caveat is not an issue at the present time and unlikely to ever be one.
I would, in general, prefer not to send the mains signal through the DCX especially after the volume control. Subs are fine.

I'm trying to get my web site redone and this is causing some delays with updating it. I would estimate the subs at about $400-500 and will be very close to the AI BB15 and BB12 http://www.ai-audio.com/products_bb12.html . I intend to add a 10" sub as well at a lower cost.
