The golden ratio of 0.618 x 1 x 1.618 will help reduce the effects of standing waves and improve system transience. To apply this ratio to a specific volume of space, simply derive it's cube root and multiply the result by each of the three factors within the ratio.
Example:
Apply the golden ratio to a Vb of 1.5ft^3
• 1.5^(1/3) = 1.447ft or 13.736in
• 13.736 * 0.618 = 8.489in
• 13.736 * 1 = 13.736in
• 13.736 * 1.618 = 22.226in
Therefore, in order for a 1.5ft^3 enclosure to comply with the golden ratio, it's internal dimensions would have to be 8.489in x 13.736in x 22.226in.
To demonstrate how large an impact the internal enclosure geometry has on the overall efficiency curve, here's a graph simulating the infinite environment response of two differently shaped 1.5ft^3 enclosures. Both feature the same driver, the same vent, and the same coordinates along which the woofer and the vent is positioned:
