Lexicon: why no crossovers at 10 Hz Interval?

Chris,

140 Hertz is the next octave above 70, and 280 is the next octave after 140. The same goes for the opposite direction, 35 is an octave below 70, and 17.5 Hertz is an octave below 35.

Octaves you double or cut in half, harmonics you add the original amount to the fundamental frequency to find each harmonic up (or down). For instance, 1 harmonic above 70 is 140, but the next harmonic up is 210, the next 280. This is why white noise has so much more high frequency information as is adds per harmonic whereas pink noise adds per octave. FWIW, this is why the Lexicon uses Pink noise (not white noise) for calibration as pink noise contains a more “balanced” or “even” complex signal.

It can get confusing.

Chuck
