Arms & Frequencies Sirs: TIME and FORTUNE, in recent comment about reproduction of recorded music, have said disparagingly that Zenith's Cobra tone arm cuts out frequencies above 5,000 cycles, and have attributed a much finer quality of reproduction to a pickup ranging out to 12,000 cycles...
...response curve of the Cobra is the result of more than three years' experimentation and hundreds of listening tests. Our human guinea pigs ranged from factory workers to outstanding musicians. We decided on the curve we finally adopted when the nonmusicians voted "Swell" and some of the musicians heard in old records nuances and even instruments that they had never known were there...
...could easily build the Cobra to almost any response curve desired. Some of our first experiments had cartridges peaked at nearly 10,000 cycles. They did not give the fidelity of reproduction, did not make each instrument speak with its own natural voice, as did the curve finally adopted. This curve, measured on response to pure frequencies, peaks at a point slightly below 5,000 cycles, falls away, and then continues out flat to well beyond 10,000 cycles...
Zenith's "Cobra Arm" pickup almost eliminates surface scratches, says FORTUNE, but in order to do so also cuts out frequencies higher than 5,000 cycles...
