1. What is a Wedge Sub Box Calculator?

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

Purpose: It helps audio enthusiasts and car audio installers determine the proper air space for subwoofer enclosures.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of wedge (cubic inches)
• \( L \) — Length of box (inches)
• \( W \) — Width of box (inches)
• \( H \) — Height of box (inches)

Explanation: The formula approximates the volume of a triangular prism (wedge shape) which is half of a rectangular box with the same dimensions.

3. Importance of Sub Box Volume Calculation

Details: Proper enclosure volume is critical for optimal subwoofer performance, affecting frequency response, power handling, and sound quality.

4. Using the Calculator

Tips: Measure and enter the external dimensions of your wedge-shaped box. For internal volume, subtract material thickness (typically 0.75" for MDF).

5. Frequently Asked Questions (FAQ)

Q1: Why use a wedge-shaped box?
A: Wedge boxes fit better in vehicle trunks or under seats while maintaining needed air space for the subwoofer.

Q2: How accurate is this calculation?
A: It's an approximation. For precise tuning, account for subwoofer displacement and port volume if applicable.

Q3: What units should I use?
A: Inches are most common for car audio, but any unit can be used as long as all dimensions use the same unit.

Q4: How do I convert to cubic feet?
A: Divide cubic inches by 1728 (12×12×12) to get cubic feet - the standard unit for subwoofer specifications.

Q5: Does this include port volume?
A: No, this calculates gross volume. For ported boxes, subtract port and subwoofer displacement from gross volume.
