Alongside Nivico (JVC/Victor, GB-1E), Grundig (Audiorama 8000) or Elipson (Chambord, way before everybody else), Tandberg also decided during its heyday in audio that loudspeakers didn't have to be square to produce music.
But, unlike a host of others during the late 50s and 60s that had disguised some of their speakers as false books (Weathers), false furniture (JBL) or false paintings (Fisher), Tandberg mainly gave the Fasett the colors and shapes of the day. Which is another way of being disguised :-)
Even if not really HI-FI, these are much better looking than the TOA p.a. speakers one can find all over planet Earth !
