1. What is a Sealed Sub Box Calculator?

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

Purpose: It helps audio enthusiasts and car audio 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: The three internal dimensions are multiplied together to calculate the total air volume inside the enclosure.

3. Importance of Subwoofer Box Volume

Details: Proper enclosure volume is critical for achieving the 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 in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Should I use internal or external dimensions?
A: Always use internal dimensions for volume calculations, as the box walls take up space.

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

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 port volume in ported boxes?
A: No, this calculator is for sealed enclosures only. Ported boxes require additional calculations.

Q5: Should I subtract the subwoofer's displacement?
A: Yes, for accurate results, subtract the subwoofer's volume displacement from the total box volume.
