Speculative Multichannel Waveguide Horn with Variable Throat Geometry (Revision 4.1)
Discipline: Speculative Engineering · Lead Researcher: Lucian Mercer
OPERATIONAL ABSTRACT
A speculative acoustic horn assembly featuring motorized internal petals that alter flare rate and throat compression dynamically during live sound diffusion. Enhanced revision 4 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
CNC-milled interlocking brass and carbon-fiber leaves slide along precision tracks, altering horn expansion cutoff from 180 Hz to 650 Hz without changing exterior horn footprint. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
