1. What is a Sealed Subwoofer Box Calculator?

Definition: This calculator determines the internal volume of a sealed subwoofer enclosure based on its dimensions.

Purpose: It helps audio enthusiasts and professionals design properly sized enclosures for optimal subwoofer performance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Internal volume (cubic inches)
• \( L \) — Internal length (inches)
• \( W \) — Internal width (inches)
• \( H \) — Internal height (inches)

Explanation: Multiplying the three internal dimensions gives the total air space inside the enclosure.

3. Importance of Proper Box Volume

Details: Correct enclosure volume is crucial for achieving desired frequency response, power handling, and sound quality from your subwoofer.

4. Using the Calculator

Tips: Measure and enter the internal dimensions of your enclosure (subtract wood thickness). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Should I use internal or external dimensions?
A: Always use internal dimensions for accurate volume calculation. Subtract the thickness of all walls.

Q2: How do I convert cubic inches to cubic feet?
A: Divide the cubic inches result by 1728 (12×12×12) to get cubic feet.

Q3: What's the ideal volume for my subwoofer?
A: Consult your subwoofer's specifications as requirements vary by model and manufacturer.

Q4: Does this account for speaker displacement?
A: No, you'll need to subtract the volume occupied by the subwoofer itself from the total box volume.

Q5: What about ported or bandpass boxes?
A: This calculator is for sealed enclosures only. Ported boxes require more complex calculations.
