Process of Making High End Stereo Speaker. Wonderful Sound Engineer of Korea

[lewdish]

Looks like Markaudio CHR-120 woofers, just a bit cut up and a Dayton Air Motion Transformer with some funny stuff at the back. That's about € 140 worth of drivers, sold for about € 2000 a pair.

If you look in the video its a modified full range CHR-70 which is like a $30 driver

Typical "high end", expensive materials and processing but doubtful engineering like for example a waveguide which with this shape most probably won't measure well.

The measurement confirmation of the problems:

"Second, I would completely redo the waveguide on the tweeter. I would make it a lot shallower in order to simplify the tweeter’s dispersion and make it a lot less jumbled."
