Solidsteel S4 Series 4 Shelf Audio Rack (Wide)

Extra-Wide Italian 4-Tier AV & Hi-Fi Rack | Brisbane HiFi Audio Specialist

The Solidsteel S4-4 is a four-tier extra-wide equipment rack designed for substantial high-end audio and home-theatre systems requiring both extensive horizontal space and multiple equipment levels.

Handcrafted in Italy, the S4-4 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 S4-4 provides four substantial platforms capable of supporting large-format components and side-by-side equipment configurations.

At Brisbane HiFi, we recommend the S4-4 for extensive systems where conventional-width furniture cannot provide sufficient equipment capacity.

Key Features & Mechanical Engineering Highlights

• Extra-Wide Dual-Component Layout: The 1,114 mm-wide shelves can accommodate two compatible full-size components side-by-side on each level, subject to individual equipment dimensions.
• 110 kg Load Capacity Per Shelf: Each tier is rated for up to 110 kg, giving the four-shelf configuration a specified combined shelf capacity of 440 kg.
• 30 mm Heavy-Duty MDF Shelves: Thick ennobled MDF platforms provide substantial structural mass and a durable polymer laminate finish.
• StratoCell-Filled Aluminium Pillars: Anodised-aluminium support pillars incorporate StratoCell damping material designed to help control mechanical energy within the rack structure.
• Differentiated Tier Clearances: The lower level provides approximately 245 mm of clearance for larger components, while the upper levels provide approximately 225 mm for source and control electronics.
• 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 expand as equipment requirements develop.

Product Specifications

Ideal for Extensive Wide-Format Systems

The S4-4 provides four substantial equipment levels, with enough horizontal space to accommodate compatible components side-by-side.

A possible configuration could be:

Top Shelf: Turntable + Phono Stage / Dual Source Components

Second Shelf: Preamplifier + Network Streamer

Third Shelf: DAC + Digital Transport

Bottom Shelf: Power Amplifier + Power Supply

This configuration can consolidate a large analogue and digital system into a single furniture structure, subject to individual component dimensions and ventilation requirements.

Home Theatre & AV Integration

The S4-4's wide platforms make it suitable for large-format AV installations as well as dedicated two-channel systems.

Potential applications include:

• Wide AV receivers
• Stereo integrated amplifiers
• Multiple source components
• Large-format digital electronics
• Centre-channel equipment where dimensions permit
• Television-associated electronics
• Combined hi-fi and home-theatre systems

Any display or loudspeaker installed 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 440 kg total shelf capacity, the S4-4 is designed to support substantial equipment loads.

Brisbane HiFi can assist with:

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

Large 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 analogue electronics.

Brisbane HiFi can assist with:

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

Modular Expansion

The S4-4 retains Solidsteel's modular architecture and is compatible with additional S4 shelf kits.

This allows the rack configuration to evolve alongside a growing system without necessarily replacing the original furniture structure.
