1. What is an RE Subwoofer Box Calculator?

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

Purpose: It helps audio enthusiasts and car audio installers 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 raw internal volume of the enclosure.

3. Importance of Proper Box Volume

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

4. Using the Calculator

Tips: Measure internal dimensions in inches (subtract wood thickness for external measurements). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert cubic inches to cubic feet?
A: Divide cubic inches by 1728 (12×12×12) to get cubic feet.

Q2: Should I account for subwoofer displacement?
A: Yes, subtract the subwoofer's displacement volume from the total for accurate results.

Q3: What about ported vs sealed boxes?
A: This calculates raw volume. Ported boxes require additional calculations for port tuning.

Q4: How thick should the wood be?
A: Typically 3/4" MDF is used, but thickness affects internal dimensions.

Q5: Does this account for bracing?
A: No, subtract bracing volume separately from the total volume.
