Optimizing Acourate Room+Speaker+Sub Correction

[fds]

Indeed, a great post. Motivated by the great articles by @mitchco and his book I got a Win PC to use Audiolense. It is certainly great but not as automatic as I had thought before starting to use it. Still it works wonders in the region below 400-500Hz in my room to the extend that some tracks - previously basically unlistenable - are quite fine now without excessive room treatments. However, so far it is a bit of give and take since some magic in the mids/heights gets lost when I use it. Also my subjective best filter generated so far creates some preringing in my case that I do not like to see. Thus, I am probably still very much at the beginning of the learning curve. I expect that the findings described by @ecwl will be very helpful for me ... also since I am currently rediscovering my little Chord Mojo in my listening room fed by OpticalModule/OpticalRendu and the sound stage depth that it is offering (previously used only on the go).
