1. What is an RE Sub Box Calculator?

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

Purpose: It helps audio enthusiasts and car audio professionals design properly sized enclosures for RE Audio subwoofers.

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: Multiply the three internal dimensions to get the total airspace volume inside the enclosure.

3. Importance of Proper Box Volume

Details: Correct 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 internal dimensions (after accounting for 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 (subtract wood thickness) for accurate volume calculations.

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

Q3: What's the recommended volume for my RE sub?
A: Check RE Audio's specifications for your specific model, as requirements vary by subwoofer.

Q4: Does this account for port/displacement?
A: No, you'll need to subtract port and subwoofer displacement from the total volume.

Q5: What wood thickness should I use?
A: 3/4" MDF is standard for most car audio applications.
