How this tool works
Introduction
This visualization helps design a balanced spherical speaker enclosure. It shows the selected solid, face-mounted 32 mm speakers, passive radiators, geometry guides, shell projection, and estimated radiation fields.
Workflow
- Read inputs. The app reads speaker count, radiator count, shape, sphere diameter, directivity frequency, and visual sound range.
- Select the shape. Suggested shapes are compared from feasible polyhedra. Mass balance and directional separation are prioritized; face count is a secondary preference.
- Place speakers. Speakers are placed first on outward-facing faces. With six speakers, the app prefers three opposing pairs. Otherwise it maximizes angular separation and balance.
- Place radiators. PRs use remaining faces, avoiding speaker faces and maximizing separation. Every PR is at least the fixed speaker diameter.
- Balance mass. Speakers are treated as heavier than PRs, and the weighted center offset is calculated and displayed.
- Fit the enclosure. The shape is scaled after positions are selected so every component fits inside its face. The Minimum action finds the smallest safe diameter.
- Render the layers. Components sit inside the wireframe, the wireframe sits inside the shell, and the LED projection sits outside the wireframe.
- Estimate radiation. Speaker coverage is interpolated from the supplied CE32A-8 guidance by frequency. The PR field uses an assumed broad ±80° spread. Cone length is visual only, not measured acoustic range.
References and limits. Polyhedra provide the unique 3D faces used by this selector. 4D polytopes are excluded when their 3D projection duplicates one of these shapes. The CE32A-8 datasheet reports 77.9 dB @ 1 W/1 m but does not provide maximum SPL, room loss, or target-level range.
