Sounds pretty damn good to me.

Disclaimer: these settings are only temporary, I'll undoubtedly be doing a lot more tweaking once I get my last (?) 2 subs and MiniDSP to complete (?) the system.

I use LFE+main too. I know I'm getting extra bass at roughly 45-100Hz, but having two more bass sources seems to make an improvement.

I don't use delay. I could, but it sounds just fine without it.

I recently calibrated a system with a mostly open rear, and like a few cases I've seen before, found rear placed subs only made a mess of the situation and bringing all the subs back to the front wall gave very good results

+1. Many room mode issues are the result of the front and rear wall being too close together. If the rear wall is a full wavelength or more distant from the LP, or when it's rendered non-reflective, rear wall problems go away. Working in large rooms in pro-sound we tend to do exactly the opposite of HT, stacking all the subs in one spot at the front of the room. Problems arise when we spread them, unless the room is large enough that they can be spread by at least two wavelengths.
