If you’re into audio systems or planning to upgrade your subwoofer, knowing the cone area is key. The cone area is the size of the circular part of the subwoofer that moves air to produce those rich, deep bass sounds.
Why Does Cone Area Matter?
A larger cone area means the subwoofer can move more air, which usually results in stronger and deeper bass. But it’s not just about size — the cone area works together with power and enclosure design to give you the best sound experience.
How to Calculate Subwoofer Cone Area
Calculating the cone area is simple:
- Measure the diameter of your subwoofer cone (in inches or centimeters).
- Divide the diameter by 2 to get the radius.
- Use this formula:
Cone Area = π × radius²
Where π (pi) is approximately 3.14.
Example:
If your subwoofer diameter is 12 inches:
- Radius = 12 ÷ 2 = 6 inches
- Cone Area = 3.14 × 6² = 3.14 × 36 = 113.04 square inches
