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."

"No wonder Klipsch stopped using Baltic Birch!"
