Quadraspire Q4 Evo

The Quadraspire Q4 Evo is a modular hi-fi rack system engineered to reduce resonance and lower the noise floor of any audio system — built from solid bamboo ply shelves with solid (not tubular) aluminum columns and feet, designed without parallel lines, and configurable to any shelf height from 100mm to 326mm. Every shelf holds up to 80kg.

Design Philosophy

What you place your equipment on affects how it sounds. The Q4 Evo addresses this through three specific engineering choices: solid bamboo shelves to suppress vibration and reduce mass, solid (not hollow) aluminum columns to dissipate energy quickly, and a geometry that avoids parallel lines — the same principle used in acoustic instrument design to minimize resonance buildup. The result is a lower noise floor, a more open soundstage, and a reduction in mechanical feedback between components.

Configuration

The Q4 Evo is modular and fully configurable. Each shelf is purchased individually with its column set and feet. The base shelf includes spikes, flat feet, or castors. Additional shelves are added at your chosen height. To build a 3-shelf rack with 256mm and 140mm heights, add: 1 shelf with spikes/feet, 1 shelf at 256mm, and 1 shelf at 140mm. Contact us with any configuration questions before ordering.
