Unbelievable

Yamaha has the same piano black finish on the sides their integrated amps---does that do anything to improve the sound?

The wood for the baffle board comes from Japan’s island of Hokkaido. Winters are extremely cold, a condition reflected in the tight grain, hardness and rigidity of the indigenous maple. With the assistance of local wood specialists, Sony hand-selected raw maple logs from Hokkaido’s forests. The trees are felled in November, when their growth slows and the grain is at its tightest."

No wonder Klipsch stopped using Baltic Birch!

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.
