Unbelievable

I bet they sound really good.  Yamaha is usually a pretty safe bet to spend your money on.  

Their motorcycles are excellent! 🤗

This is a mystery. As we know, Hattori Hanzo lives on Okinawa, so it is unlikely that he planted trees on Hokkaido. Then again, the making of a katana involves the lamination of different forms of steel, soft, medium and hard steel. The types of lamination and the number of layers varies between sword makers. So it is possible that Yamaha could have convinced Hattori to come out of retirement to consult on wood lamination design for these speakers. Knowing Hattori, he probably made Yamaha sign a NDA. If Yamaha violates the NDA, their corporate leadership would be deemed “Rats”, and we know how that would end. Yes, it’s a mystery.

"No wonder Klipsch stopped using Baltic Birch!"

The story of SONY speaker has the second part, too.

"However, building the entire enclosure from a single type of wood can result in an excessively rigid and hard sound. For this reason, we selected another, somewhat softer cold-climate wood, Scandinavian birch, for the speaker’s side and rear panels. The birch is laminated and compressed to a thickness of 32 mm for the AR1, 24 mm for the AR2. The panels are then curved to a sculptural shape.

This unique choice of woods insures exceptional freedom from unwanted vibrations, as well as a natural, balanced, musically expressive tone.

You’ll remember the density of these woods every time you move the loudspeakers. Although these are not giants, the SS-AR1 weighs 126 pounds while the SS-AR2 weighs an impressive 84 pounds."

They are not Yamaha.
