Great analyses, David, thanks.

I can’t concur as now with anything. Macondo in the room with midbass horn was a complex installation and with ULF it became even more complex. Some of the things I setup by ear and do not use measurements, I just know how the things have to sound. Of course I do measure the things but I do not always pay attention to it in a normal sense. Over the years I leans Macondo well and I have learned how my measuring techniques correlates with Sound, so it very handy to measure, to make decisions and to listed by the same person. I am saying it as there are quite a number of strange measuring monuments in my setup but all together it somehow works very well.  I do not talk about it as I do not think anybody would have interest but some of those logical anomalies do make to think about the reasons, to define my own rules and setting up shortcuts.

I do not do in-phase vs. out-of-phase experiment as I know what need to be in in-phase and what has to be out-of-phase in Macondo. What however fascinated me was the correlation of response of one channel with the same channel complimented by other channel. This is a very interesting way to see what is doing on and a very powerful tool for speaker room integration.  My very minor towing in and out speaker it was possible to fine tune some upper mid range attenuation and I was truly good with it. Why I am saying in past tense? Because my “new” ULF channels completely override this. The ULF linearised response of both channel in very funny manner making combined Macondo channels to sound practically identically to each individual channel, The individual channels of cause are “tactically linear”.

When you were saying about stereo recordings with phase differences between the channels in specific frequency range then you hit a very direct target of what I was thinking another day. Having the whole 14 channels in time-alignment it is very funny to see how people who record with multi-microphones are fucking the things up. Some time they use highlight mics with time delays and set the delays in wrong way. When it happens is sounds so brutally stupid….
