Sorry I thought I answered this. I have not heard the Lyngdorf system so I don’t what to think about it. I assume it’s a good product (to have a business actually survive on it), but worth the money? No idea.
In your video he talks a lot about the "Story" behind the model he designed, so if you are a fan, it’s a cool video. If you don’t know anything about Lyngdorf, they’re inner tech, you won’t learn much from this. These kinds of videos are effective and convincing you when someone smart like this starts talking about bass that is "so fast, it’s like a real live concert". You tend to believe them but they actually say little about the support information that proves what they are saying is actually true.
John Meyer, Billy Woodman (ATC), Ilpo Martikainen (Genelec), Raymond Cooke (KEF), these folks knew what they are talking about and got straight to it.
By the way, I don't think John Meyer had the first active studio monitor, that was Genelec in the very early 80s. I know as I was hauling their samples round Chicago in the early 80s. No one wanted to hear it! ATC was also building active systems around this time, locally in the UK, mostly custom systems for specific buyers. The Meyer HD1 which had some success for sure, came a bit later, around 1990. By this time Genelec and ATC was already installing large far field active monitors. In the UK ATC had customers like the Astoria Boat owned by David Gilmour. Genelec already well on its way in the monitor business in the US with an active small meter bridge monitors (1031) that completely dominated LA movie score mixing and music recording. You still find people using them!
