Your sub experience: Easy or hard?

@mijostyn --

Please let me know what you find out when having gone through the Pre8’s manual. I have no experience with the previous line(s) of DEQX units, nor the Trinnov Amethyst for that matter, but learning of your findings would certainly give me a bearing on whether to seriously consider the Pre8 as a future acquisition. My Xilica digital XO has given me a taste of flexibility and rather elaborate settings to work from, so I wouldn’t want to give that up with a new unit either. Connectivity range with the Xilica is a bit limited though, so seeing that being given a boost wouldn't hurt, and fortunately the Pre8 has that to offer. 

Good question, Erik!

One thing that made setting up a pair of subs much easier for me was to put a 2’x4’ x 6" Owens Corning 703 fiberglass panel in each front corner.   I plan to add a second pair in the rear wall corners.

I also have successfully used an Anti-Mode DSPeaker to help with room correction. Ultimately it was a matter of trial and error and making sure I didn't become obsessive.

Bass traps, properly used, are magical.  I use them both for subs and for two ways and it never ceases to amaze me how much better my life is thanks to them.  I simply lack some of the main bass issues (sub or no) others might contend with.

The Owens Corning 703 works a lot better for me than the 12" ASC traps I once had.
