Solidsteel Supports Gain Scientific Validation

Solidsteel's globally recognised anti-resonance vibration-damping systems have scientific validation for the performance of its products.

After over three decades of producing popular hi-fi component supports alongside loudspeaker and amplifier stands, not to mention platforms for musicians, Solidsteel has gone the next step to gain scientific recognition for its anti-resonance and vibration-damping designs.

Solidsteel scientific certification

A series of technical studies were conducted with the expertise of Prof. Ing. Dario D'Orazio, an acoustics professor at the University of Bologna's Mechanical Engineering department, and his research team. These studies aimed to analyse the vibroacoustic characteristics of the S5-3 and HF-4 electronics racks, chosen as they represent key models from the Solidsteel catalogue, along with the iconic SS series speaker stands.

The main objective of the analysis was to identify the parameters describing the vibroacoustic behaviour of the systems under real-use conditions, with a particular focus on the materials used. This allowed for an accurate evaluation of the coherence between the system's performance quality and its corresponding cost.

Both the S5-3 and HF-4 racks were placed inside the electroacoustic listening chamber of the University of Bologna. Frequency response was measured using a pair of accelerometers positioned on different furniture components. To simulate real-world usage, both mechanical and aero-acoustic excitations were applied. A mechanical impulse was generated using a calibrated hammer, while aero-acoustic excitation was provided through a frequency sweep emitted from the chamber's audio system.

The results indicated that both racks effectively decoupled the shelves from each other and the structure from the floor.

The SS series stands also underwent a similar analysis to characterise their vibroacoustic behaviour, highlighting strengths and areas for improvement. A speaker was placed atop the stands, playing a frequency sweep, while accelerometers placed on different parts of the stands captured frequency response. This setup effectively replicated real-world usage.

The results showed that the stand decoupled the speaker from the structure, reducing signal transmission by 10-15 dB, especially at low frequencies. The stand's high structural rigidity, due to both its geometry and material, played a crucial role in its optimal performance.

applause awards

Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.

Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.

The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.

We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
