What happens when loudspeaker design meets 3D printing? RD Physics explores why the sphere may be an almost ideal enclosure—rigid, material-efficient, visually striking, and capable of reducing diffraction—while tracing five generations of compact full-range speakers built with everything from carbon fiber skins to metal-filled filament and gyroid infill. It’s a fascinating look at how additive manufacturing opens up shapes, structures, and DIY possibilities that traditional cabinetmaking simply can’t match.

Just before our editorial cutoff for the September's Muse, a YouTube video dropped that explores the measured differences between 3D printed spheres and 'golden ratio' rectangular cabinets. The creator attempts to limit the variables between them and also add additional 'gyroid' cabinet fill (which is rapidly becoming popular in speaker design - see Node Audio's designs).
