Solidsteel S4 Series 2 Shelf Audio Rack (Wide)

Extra-Wide Italian 2-Tier AV & Hi-Fi Rack | Brisbane HiFi Audio Specialist

The Solidsteel S4-2 is an extra-wide two-tier equipment rack designed for large-format hi-fi and home-theatre systems requiring substantially more horizontal space than a conventional equipment rack.

Handcrafted in Italy, the S4-2 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 S4-2 provides substantial space for wide electronics, multiple components positioned side-by-side, or larger AV equipment.

At Brisbane HiFi, we recommend the S4-2 for systems where conventional-width furniture is restrictive and additional horizontal equipment space is required.

Key Features & Mechanical Engineering Highlights

• Extra-Wide 1,114 mm Platform: The generous shelf width allows two compatible components to be positioned side-by-side or provides space for larger-format audio and AV equipment.
• 110 kg Load Capacity Per Shelf: Each level is rated for up to 110 kg, providing substantial support for heavy amplifiers, large AV receivers, turntables, and other high-mass 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.
• 325 mm Lower-Level Clearance: The generous lower shelf clearance accommodates tall amplifiers, valve electronics, monoblocks, and other large-format components.
• 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: Optional S4 shelf kits allow the rack to be expanded as equipment requirements grow.

Product Specifications

Ideal for Wide-Format Systems

The S4-2's 1,114 mm width provides substantially more horizontal space than conventional hi-fi racks.

Potential configurations include:

Top Shelf: Turntable + Phono Stage / Two Source Components

Bottom Shelf: Wide Integrated Amplifier / AV Receiver / Power Amplifier

Alternatively, the generous width can accommodate compatible large-format electronics side-by-side.

Equipment dimensions should always be checked before installation to ensure adequate clearance and ventilation.

Home Theatre & Display Applications

The S4-2 can also be considered for integrated audio-visual environments where wide equipment platforms are advantageous.

Potential applications include:

• Wide AV receivers
• Stereo integrated amplifiers
• Multiple source components
• Centre-channel or display equipment, where dimensions and loading are appropriate
• Large-format media systems
• Combined hi-fi and television installations

Any display or centre speaker installed above the rack should be independently assessed for weight, dimensions, stability, and manufacturer requirements.

Heavy-Component Load Planning

With a specified 110 kg capacity per shelf, the S4-2 is suited to substantial equipment.

Brisbane HiFi can assist with:

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

Large amplifiers and other heat-generating components should retain the ventilation clearances specified by their manufacturers.

Turntable Integration

The generous upper shelf provides substantial space for a turntable and associated source equipment.

For analogue systems, Brisbane HiFi can assist with:

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

Modular Expansion

The S4-2 uses a modular architecture that allows compatible S4 shelf kits to be incorporated as the system develops.

This provides a pathway from the initial two-tier configuration toward a larger equipment installation without necessarily replacing the entire rack.
