Yamaha really made this statement:

Glossy black piano finish provides improved signal-to-noise performance



I thought I would seek opportunity to hear these speakers, but now I do not think so






regardless of whether or not the finish on the front of speakers can affect the reflected sound, the advertisers have probably never met the engineers, so I say go ahead and listen...
If we start culling out gear because it might be over hyped, what's left? Enjoy the music
Unless they can certify the plywood from the island of Hokkaido was trees planted by Hattori Hanzo I would pass.
The whole list of features is overdone hype especially

  • Carefully crafted laminated plywood enclosure made of Japanese white birch from the island of Hokkaido.

but I love how they finish the list with a simple  and very understated "frequency dividing network"
