Unbelievable

Say, isn’t Hokkaido where the epicenter for coronavirus was? Ah so desu ka! The Baltic is most likely at higher latitudes than Hokkaido, anyways.

So, with a nod to Kenjit, the ultimate speaker cabinet material should be dwarf star alloy?  Density beyond your wildest schemes...
Good luck keeping them in your listening space....;)

"Dear?  How come there's 2 holes in the floor....?"

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.
