One speaker.
Thirty parts.
Everything here comes out of a Ø200 mm print bed, a bag of drivers, and one node board. Scroll to take it apart. Drag to orbit any time.
Model regenerates from cad/; hardware is dimensioned from datasheets where they exist and marked as estimates where they don't.
Two layers,
carved in.
The Voronoi is not a sleeve — it is cut into the 7 mm wall. A first layer of tall cells goes 2.5 mm deep; inside each, a finer Voronoi goes 1.5 mm deeper. What is left between them is a rib network at full wall thickness: the pattern is the bracing.
Every cell is roofed at ≤ 50° so it prints support-free, standing up. Each segment gets its own seed; no two are alike.
Segments,
sealed with O-rings.
Four Ø200 segments — base, bass, woofer, tweeter — each under the 200 mm print height. A spigot drops into the socket below it; a 2 mm nitrile cord in the groove makes the joint airtight at 22 % squeeze.
The Voronoi relief is carved into the wall in two nested layers; the ribs between cells plus ring ribs inside keep the printed shell quiet.
Norex, silk,
and a printed horn.
The woofer sits on a swap-in plate that fills the body's window — one body, a plate per driver tier. Above it the SB26STCN dome sits in the back of an oblate-spheroid waveguide, the one part a printer makes better than a factory.
Waveguide profile: 45°, Ø85 mouth, 34 mm deep. Swap the insert, keep the crown. Swap the plate, keep the body.
A fourth driver
aimed at the ceiling.
The crown's top is open; the Atmos head drops onto the same spigot: its own sealed volume, a top plate tilted 20° toward the listener, and a 3" full-range firing upward so the bounce lands at the seat.
Fed by the fourth amp channel; the renderer sends it the height objects only.
Power and music
down one cable.
PoE+ in, 24 V out. An ESP32-P4 keeps time with the hub to under a microsecond over IEEE-1588 and feeds two TAS5825M class-D amps over one TDM bus: four channels, 25 W budget, DSP crossover in firmware.
Two MEMS mics — one behind the baffle, one in the crown — measure the speaker in the room it is in.
