fiogf49gjkf0d This type of the “time alignment” has as much to do with time alignment as if they whistle into the horn and observe the re-entering echo. What they do is perfuming the ritual dance in front to the loudspeaker that called “trade show ballet”. The Sit-Down testing is useful but for VERY different purpose sand they have nothing to do with speaker setup but rather for drivers TTH matching. From what I see in the video the Tweeter is not time aligned to MF anyhow and the only alignment they are trying to do is the alignment in-phase in comb-filtering zone. I mean they are tiring to set up the tweeter peak to be at the same peak as MF but a few periods delayed. This type of setting is possible by ear but you would never know to witch peak you aligned. They might have some kind of marking on the horn to see where the driver shall be and then they try to fine tune by ears. In any case it has nothing to do with time alignment. In fact if the people do understand the importance to have peaks synchronized even in time misaligned zone and if they despite the understanding still perform that bizarre padede instead of have very simple measuring tools then I question how much they care about the result.

fiogf49gjkf0d Yes, I noticed midway through the movie that they were not time aligning the drivers but it was to late to rename the topic (should have watched it all the way through before posting).
I wonder if the large majority of these japanese multi-driver horn assemblies is not time aligned because of their wish to keep the speaker from growing vertically...

If I understand time align well it can by also horizontal. They can align mid and highs...
