Pioneer CS-77A Speakers
Pioneer CS-77A Vintage Speakers 1971 All Information:
The Pioneer CS-77A is a bookshelf type system, perfect for compact quarters, that handles a full 65 watts of music input but can be used with a relatively small power amplifier.
The enclosure is made of genuine walnut, hand finished, and a pleated saran grille cloth and grille gives the distinctive look of fine furniture.
The woofer and the midranges have high quality cambric surrounds, so they
won't rot or deteriorate the way foam surrounds do.
These speakers employ Pioneer's "FB" pulp material in the woofer and
midrange drivers. These pressed cones are made of specialized pulp material
that is stiffer and has better damping than standard paper cones. The result is
audibly different with solid and deep base that sounds natural and not
boomy.
Midrange presence is outstanding with the characteristics of the "FB" cone
material.
