@3db , first off sorry about your wife. I hope you can find some comfort and enjoyment in the near future as you go through this tough time. Hoping I can help, even in a tiny way. But remember that it's a process and there are professionals who can help you through it.
My first impression is that your initial measurements look really good in the low bass. I'm impressed you're getting that flat of a response. The mid/high bass has a lot more variation, but on average you look pretty good.
That said, a second sub always helps you even the response throughout the room, so of course we're going to recommend that. But you're on the right track thinking about miniDSP too. Having individual phase and delay controls solves most of my room's issues, before using DSP to really fine tune. It was a revelation for me!
Here's what I learned from using miniDSP and REW to tackle the challenges of my room. the miniDSP takes time (expect hours of playing, and then when you get close, starting all over and getting a bit better
).
So I’ve been taking some measurements with REW for a few weeks now and the MiniDSP I ordered will be here tomorrow. I’ve always had a dip at 90-100hz roughly and tonight I tried different crossover points, distance setting and eventually multiple locations for one of my 4 subs and my Mirage...
