@tundratoad no problem and you can message me privately if you want to discuss this further.
I understand that the process "looks" tedious and long, but it is not, to the contrary it is a lot of fun to listen how the sound changes shape.
I learned this process/sequence from 2 of the best sound engineers there are in the EU, they both have a PhD in the sound physics field, and own 2 different companies that all what they do is room acoustics, from residential, to concert halls like the new Munich Symphony Hall.
I hired them to do all my 3 listening rooms in my primary home in Spain and the results are nothing sort of magical. I have been working with them for years, each time I change a component like speakers, amps, pre-amps I call them back to re-tune the rooms. I have been doing this for years, so by now we have become more friends than customers.
So I tried to do the same in the living room in my house in the USA. Granted I do not have the same gear they do, I have REW and 1 microphone, they have different hardware and software and use ~20-30 microphones in my rooms, but the process is similar and I believe that I have done a decent job. I still have to do some changes before where I need treatment if I end up needing it without overwhelming the living-room.
I have all my REW measurements, which I gave to one of them and they will let me know what to do next.
Is your system solid state?
