• Internal bracing for durability and vibration control
• Designed for rugged use in mobile and event audio setups

📢 Disclaimer:
I do not claim ownership of the original design. This build is a custom interpretation intended for educational and tribute purposes only.

I am not a professional sound engineer. All tuning, frequency responses, and performance assumptions are based on general calculations and DIY methods. Actual results may vary depending on your drivers, materials, and tuning environment.

📌 For accurate design, always consult with a professional audio engineer or use simulation tools like WinISD or Hornresp.
