The Horn Range
Five bodies, one physics — from a pocket-money passive horn to a granite floorstander.
These are drawings of the CongoSky functional-art speaker range: five
back-loaded horns that share a single idea — one full-range driver, the cone's rear
wave folding downward as the horn and the pedestal, opening in a flower-cone mouth. The horn
geometry here follows the real closed-form acoustics of the
design instrument next door
(f_c = m·c / 4π). Illustrative cross-sections, not to scale, and not
a measurement — the shape a microphone will one day confirm.
These are drawings, and they say so
Illustrative cross-sections in the house style — not photographs, not renders, and not to scale. The horn shapes are drawn to follow the real geometry the design instrument computes (an expanding flare whose rate sets the cutoff; a folded path that tunes the bass), so the picture is honest about how these actually work. The final form is the ceramicist's hand; the final sound is a calibrated microphone's verdict. Modelling is not measurement.
