Fibonacci Waveguides 1.618 fully printed
Key Benefits in Modern Car Audio In high-output car audio systems achieving 150 to 160 dB with sealed doors, traditional mid-range drivers in door or kick panel locations are prone to damage from excessive sound pressure.

Installation Versatility Designed for under-dash mounting similar to original USD models. A prototype pillar-mounted version is available, a novel adaptation for A-pillars. This custom design is adaptable to various vehicle models. 3D printing enables precise control over material thickness to minimize resonances, ensuring consistent performance in demanding environments. Features • Inspired by USD Audio WaveGuides for proven sound quality • Fibonacci curve geometry for natural sound wave guidance • Variable wall thickness to reduce vibrations • Under-dash or A-pillar mounting options • Compatible with high-SPL car audio setups • Fully printed in durable PETG material • Choice of color for custom aesthetic • Fully Printed Package • Complete pair of waveguides, fully printed and ready to install • Includes all necessary parts and components to connect to a USD audio driver or similar • Professional 3D printing services via our dedicated printing farm • Material: High-strength PETG for optimal acoustic performance and durability • Custom color options available$220 for a pair 2x (includes printing only).
