KEF ls50 meta’s are on the way

Kenjit if you read the white paper, which is very well written, you will see the attenuation is down to 620hz not just the range of the tweeter and there are measurement charts that show it. Also that there is a lot of science and expertise that went into the technology to enable its high performance.

the attenuation is down to 620hz not just the range of the tweeter

How do you attach the absorber to the drive unit so that it stops absorbing below 620hz? I dont see how that works.

The white paper covers the implementation pretty well. If you have questions best to ask the experts ie the engineers at KEF. I suspect you would get a response if you inquire.

   Interested in hearing the Metas. A close friend had a pair of LS 50s in his office, Exposure components upstream. I really enjoyed them. If the Metas are appreciably better, they will probably set a new standard in their price class. 

You cant absorb down to just 600hz and call it a day. What abut the range from 600hz to 50hz? Why is it okay for that to be ignored?
