August 1963 - Produkt-Neuvorstellungen in den USA

Diese August-1963 Ausgabe ist darum so besonders interessant, weil gerade in 1963 zwei herausragende Innovationen von einer Funkausstellung aus Europa in Berlin (auch im August 63) kamen. Das war der neue DUAL 1009 Hifi-Plattenspieler und der Philips CC-Recorder. Beide Produkte schrieben im Anschluß Weltgeschichte. Und davon ist in der US-Ausgabe noch nichts zu lesen. Warum die ganz normalen Presseinfos bei den US-Importeuren bezüglich dieser europäischen Neuigkeiten nicht angekommen waren, ist nicht mehr zu ergründen.
Hier kommen also die Hifi-Neuvorstellungen 1963 aus US-Sicht.

LOUDSPEAKER MECHANISMS

Amerika war damals im sogeannten Kit-Fieber. Vermutlich auch aus Preisgründen baute jeder sein Stereo-Sytem selbst zusammen und war damit glücklich - weil selbst gemacht. Erst Jahre später kam die Erleuchtung, es klingt bescheiden. Die neuen fertigen Boxen auf dem amerikanischen Markt klingen erheblich besser als die mühsamen Selbstbauten. Die beiden Firmen AR und KLH räumten dann den Markt ab mit hunderttausenden von fertigen Boxen.

• Patrician 800. - Latest in a series of four-way loudspeaker systems utilizing a 30-inch foam-cone woofer, a 12-inch mid-bass driver, diffraction horn treble, and very high frequency drivers. Crossover network 12-db-per-octave with crossover frequencies of 100, 800, and 3500 cps. The superiority of the Patrician 800 over its predecessors is due in large part to the use of the 30-inch woofer, giving it efficiency and extended bass response. Although designed for corner operation, the Patrician 800 can be placed in almost any room location without seriously hampering its performance. Its bass enclosure, of an entirely new design, consists of an airtight chamber behind the 30-inch woofer and a straight axis horn, the mouth area of which leads from the front of the woofer into the corner of the room. Distortion is minimized by the use of four separate drivers, each operating in the specific range to which it is best suited.
