KS 445

Another triphonic assembly in this set. At that time, it was a popular technology for the Grundig engineers, essentially for density reasons more than for the cost. An elliptic loudspeaker reproduces the bass tone on the central channel, while 2 mid-tone loudspeakers disposed at the ends of the tilting front panel and two tweeters on the sides of the cabinet diffuse the high part of the spectrum.
