Quadraspire Q4 Evo Hi-Fi Racks

Shelves shaped to avoid resonance

Quadraspire says parallel lines on rectangular shelves encourage resonance, so where possible it avoids them, as most musical instrument designs do. The Q4 Evo shelves have curved edges to their front and back.

Quadraspire says the shelves are machined to reduce resonance, lowering the noise floor and opening the soundstage, and that the chamfered edges help dissipate energy.

Solid bamboo ply and aluminium columns

Quadraspire says it chose solid bamboo ply after testing materials, because it suppresses vibrations and is carbon neutral. It says materials like glass resonate and distort the sound.

The columns and feet are solid aluminium. Quadraspire says steel tube can resonate and aluminium has much less resonance. The Q4 columns are 32 mm diameter curved SV columns in black or matt silver.

Build it your way

The Q4 range is modular. Quadraspire lists column heights of 100, 140, 180, 216, 256 and 326 mm, and a choice of spikes, flat feet or castors.

Quadraspire recommends not going above 8 tiers or 1500 mm for the whole frame, for performance and appearance. Each shelf holds up to 80 kg.
