The Fibonacci Sequence
Out of sheer fun, the great mathematician Leonardo da Pisa, called Fibonacci, described in AD 1202 the growth of his rabbit population with the infinite sequence of natural numbers, henceforth known as the "Fibonacci sequence".
1, 1, 2, 3, 5, 8, 13, and so on.
This sequence of numbers is known to steadily approximate the Golden Ratio, an immensely important approach when it comes to designing our loudspeakers. We consider these aspects as much as possible, for example in the inner and outer proportions, the acoustic contexts, even with the internal wiring!
The date disc of our watch has a little hint to this: Each day of the Fibonacci series is marked in our special red.
