Quadraspire Q4 Evo Hi-Fi Rack

What you place your hi-fi equipment on will affect its performance. Placing your equipment on a Quadraspire Q4 Evo hi-fi rack will help reduce resonance, lower the noise floor and open the soundstage to make your hifi sound even better.

Avoid Parallel Lines

Parallel lines on rectangular shelves encourage resonance which can distort sound. Where possible, Quadraspire avoids parallel lines in the same way as most musical instrument designs.

Intricate Machining

The shelves on Q4 Evo racks are machined to reduce any resonance, lowering the noise floor and opening the sound stage whilst also improving sound quality and performance. The edges on all shelves are chamfered to help dissipate energy and help improve sound.

Materials

Quadraspire uses aluminium to manufacture all of the columns and feet used in Q4 Evo racks. Aluminium has much less resonance than the steel tubing used in many competing products.

Some shelf materials like glass can resonate and distort the sound of your system. After extensive testing of many different materials, Quadraspire uses bamboo ply which suppresses vibrations and is also carbon neutral and sustainable.

Choose Floor Spikes, Flat Feet or Castors

The base shelves of Quadraspire Q4 Evo racks are fitted with floor spikes as standard, but are available with a range of alternative feet options. Choose between floor spikes, flat feet and castors to best fit your requirements.

Floor Spikes

These adjustable floor spikes provide excellent isolation and easy levelling. Partner with floor protectors for use on hard floors.

Flat Feet

These flat feet have a hard rubber sole. They are great alternative to spikes and floor protectors for hard floors.

Castors

These high-quality castors make it easy to move your rack from one place to another.

Locking Castors

Just like the regular castors, but with the addition of a locking mechanism to prevent unwanted movement.

Bronze Upgrades

It is no coincidence that a lot of musical instruments use brass and bronze. Quadraspire’s research determined that bronze and brass are good materials for reducing resonance, so they developed a bronze upgrade for all of their Q4 Evo and SVT racks.

Bronze upgrade

The shelf with bronze upgrade is designed to sit directly on top of an existing top shelf, providing improved isolation.

Bronze upgrade with columns

The shelf with bronze upgrade and columns provides a bronze top shelf together with columns to provide extra space below.

Floor Protectors

Floor protectors are designed to sit under floor spikes, preventing damage to hard floors and improving acoustic isolation. Quadraspire offers a choice of high-quality stainless steel floor protectors to protect your flooring while enhancing sound performance.

QC Floor Protectors

QC floor protectors provide a simple and cost effective option. They protect hard floors and improve isolation.

QX7 Floor Protectors

The advanced QX7 floor protectors are intricately machined and shaped to provide improved isolation performance and sound quality.
