Recommended Fusion® Subwoofer Enclosure Volumes
All Fusion® subwoofers have an optimal enclosure size that is based on a specific tuning point.
To calculate volume for a given enclosure, a calculator and tape measure will be needed to apply the formula.
In inches, Length x Width x Depth divided by 1728 = volume in cubic feet
In centimeters, Length x Width x Depth divided by 1000 = volume in liters
In liters, volume divided by 28.317 = volume in cubic feet
Always account for the volume of the subwoofer that will be inside the enclosure. When calculating the volume of an enclosure, use the inside dimensions to account for the thickness of the material being used.
