Tip of the Week
The Golden Ratio is based on the 'Golden Number' from ancient Greece, Phi. Phi (1.618033988749895...) is considered an irrational number like Pi (3.14159265358979... you probably remember this concept from geometry class). Phi is present throughout the natural world. The growth pattern of many organisms, bucky balls, and Quantum Physics are just a few examples.
The Golden Ratio refers to the ideal ratio for height, width, and depth of a speaker enclosure to reduce internal standing waves which is 0.6: 1.0: 1.6 (Phi). The details are very mathematically specific and have to do with sound wavelengths in relation to the lengths of the internal walls of a speaker cabinet. Regardless, however, if you're a math genius or not, if you have a speaker cabinet that follows the 'Golden Ratio', internal standing waves will be greatly diminished.
