The Magnasonic Special
This Magnasonic Special Model K-CP297F Phonograph came with
a 10-watt amplifier, AMP-169AA. It has four speakers, 15" bass,
8" mid-range, and two 5" high frequency. Also, the set-up
included a Model S-29 matching 3-speaker cabinet. It wasn't
available anymore, probably ended up in the dump. Original cost
for this "Magnavox full-console 7-speaker Stereophonic High
Fidelity System" in 1958 was $279.50.
