quarter-wave theory
Martin J. King's Mathcad worksheets are a specialized suite of simulation tools widely used in the DIY audio community for designing high-performance loudspeaker enclosures, specifically those based on . Overview of Worksheets
- Beyond the Piston: King acknowledged that the air inside a cabinet is not a simple spring; it has mass, friction, and resonances that change with frequency. His worksheets predict the peaks and dips in frequency response caused by these standing waves.
- The Stuffing Variable: One of King’s most significant contributions was his modeling of acoustic stuffing (damping material). His worksheets allow users to simulate how different densities of polyfill or wool affect the speed of sound and damping within the line. This allowed DIYers to smooth out ragged frequency responses without endless trial and error.
- Iterative Design: The Mathcad interface allowed users to instantly see how changing a dimension—like the length of the line or the taper angle—affected the impedance curve and SPL output.
While modern users often gravitate toward slick, graphical commercial software, King’s worksheets remain a gold standard for understanding the physics behind the sound.
