If your sub has speaker/high-level connections, I guess by definition it’ll work for both in this setup since everything goes through the integrated amp to the speakers. Personally I’d optimize it for 2-channel and just let those settings fly for HT whatever that gives me. The downside is you won’t be getting the LFE signal from the AVR so you’ll be missing out on some of the HT experience. For me this would be a fine compromise since stereo is more important to me and I think HT performance would still be very acceptable, but YMMV.
If if your sub doesn’t have speaker-level connections, this goes beyond my already meager understanding of the subject and I got nuthin’.
In a perfect world I guess you’d have a sub with both speaker and line level inputs and use one for stereo and the other for HT and be able to switch between the two, but I have no idea if such an animal even exists. I’m sure others more knowledgeable on this subject will be much more helpful and correct any errors in my recommendations, but just wanted to get something started here.
