Solidsteel S4 Series 3 Shelf Audio Rack (Wide)

Extra-Wide Italian 3-Tier AV & Hi-Fi Rack | Brisbane HiFi Audio Specialist

The Solidsteel S4-3 is a three-tier extra-wide equipment rack designed for comprehensive hi-fi and home-theatre systems requiring substantial horizontal and vertical equipment capacity.

Handcrafted in Italy, the S4-3 combines 30 mm-thick ennobled MDF shelves, a rigid anodised-aluminium support structure with StratoCell damping material, stainless-steel hardware, and adjustable M8 floor spikes.

With an extended 1,114 mm shelf width and a specified 110 kg load capacity per shelf, the S4-3 provides generous space for multiple full-size components, wide-format AV electronics, or carefully configured audio-visual installations.

At Brisbane HiFi, we recommend the S4-3 for systems requiring substantial equipment capacity without moving to separate racks for audio and video components.

Key Features & Mechanical Engineering Highlights

• Extra-Wide 1,114 mm Shelves: The generous width allows two compatible full-size components to be positioned side-by-side on each level, subject to their dimensions.
• 110 kg Load Capacity Per Shelf: Each tier is rated for up to 110 kg, providing substantial support for heavy amplifiers, turntables, AV receivers, and other large-format equipment.
• 30 mm Heavy-Duty MDF Shelves: Thick ennobled MDF construction provides a substantial mounting platform finished in durable polymer laminate.
• StratoCell-Filled Aluminium Pillars: Anodised-aluminium support pillars incorporate StratoCell damping material designed to help control mechanical energy within the rack structure.
• 245 mm Lower-Level Clearances: Both lower equipment levels provide approximately 245 mm of vertical clearance, accommodating larger components while providing useful ventilation space.
• Adjustable M8 Stainless-Steel Spikes: Precision-adjustable floor spikes allow accurate levelling and establish a defined mechanical interface with the supporting floor.
• Protective S Series Floor Pads: Included floor discs help protect timber, laminate, tile, and other finished flooring from spike contact.
• Modular S4 Architecture: Compatible S4 shelf kits allow the rack to be expanded as equipment requirements grow.

Product Specifications

Ideal for Wide-Format Multi-Component Systems

The S4-3 provides three substantial levels for systems containing multiple audio and video components.

A possible configuration could be:

Top Shelf: Turntable + Phono Stage / Two Source Components

Middle Shelf: Integrated Amplifier + Network Streamer / DAC

Bottom Shelf: Power Amplifier + AV Electronics / Additional Sources

The 1,114 mm width can accommodate side-by-side equipment where dimensions permit, helping consolidate a large system into a single furniture structure.

Home Theatre & AV Integration

The S4-3's wide platform makes it suitable for installations combining high-fidelity audio with home-theatre equipment.

Potential applications include:

• Wide-format AV receivers
• Stereo integrated amplifiers
• Multiple digital sources
• Centre-channel equipment where appropriate
• Television-associated electronics
• Combined music and home-theatre systems

Any display or loudspeaker placed on or around the rack should be independently assessed for weight, dimensions, stability, and manufacturer requirements.

Heavy-Component Load Planning

With 110 kg capacity per shelf and a specified 330 kg total shelf capacity, the S4-3 is designed for substantial equipment loads.

Brisbane HiFi can assist with:

• Horizontal load distribution
• Component dimensions
• Equipment weight
• Amplifier ventilation
• Side-by-side component placement
• Cable routing
• Future expansion

Heat-generating equipment should retain the ventilation clearances specified by its manufacturer.

Turntable Integration

The spacious upper shelf provides considerable room for a turntable and associated analogue equipment.

Brisbane HiFi can assist with:

• Rack levelling
• Turntable positioning
• Mechanical isolation
• Tonearm cable routing
• Speaker positioning
• Floor-vibration considerations

Modular Expansion

The S4-3 uses Solidsteel's modular architecture and is compatible with additional S4 shelf kits.

This provides a pathway for expanding the system as additional components are introduced without necessarily replacing the complete rack.
