I Built a 4-Inch Subwoofer Using ONLY Laser-Cut Wood!

Can a tiny, 4-inch DIY subwoofer actually deliver deep, impactful bass? In this video, I take on the engineering challenge of designing and building a high-performance micro-subwoofer from scratch. Unlike standard drivers, I focused on precision fabrication using 3mm laser-cut wood to create a rigid and acoustically optimized enclosure. This project explores the intersection of mechanical design and audio engineering to see how far we can push a small-scale driver. In this video, you will see: ✅ The design philosophy behind the 4-inch driver. ✅ The fabrication process using 3mm laser-cut wood for maximum rigidity. ✅ Assembly and testing the acoustic response. ✅ The final result: Can it actually handle the lows? This is the second video on the IRAUDIO channel, where we dive deep into DIY audio systems, restoration, and acoustic engineering.
