Worth Knowing

As with many other products, the story behind certification labels for acoustic fabrics is often more complex than customers initially realise. All too often, these labels involve a fair amount of window-dressing and greenwashing, with limited real-world benefits and significant costs for manufacturers and retailers. Even reputable certifications aren’t without their flaws. Here, we explain why we’ve decided to part ways with Oeko-Tex®.


Testing textiles for harmful substances is a complex field. There is a good reason for that. The health risks associated with the various substances that may be present in textiles are very real. These include heavy metals, pesticides, formaldehyde, and residues from chemical finishing processes.
All the more reason to look closely at what is actually being tested. Not every certification label means what people assume it means at first glance, and most certifications come with considerable costs that ultimately increase the price of the product. One example is the Oeko-Tex® Standard 100, a certification we oursel

Alongside the core characteristics, standards, and technical specifications relating to speaker cloth, sound transparency and frequency response in particular,  possibly also protection against mechanical impact or splash water, and fire safety, there is a whole range of additional standards and parameters which may initially appear secondary, yet still provide valuable information about the suitability and quality of a speaker fabric.


Colour fastness, wash resistance, pilling or dimensional stability may sound more like the language of clothing textiles or upholstery fabrics than loudspeaker construction, acoustic ceilings, home cinemas, or studio interiors. In practice, however, such properties play a decisive role in determining whether an acoustic fabric will still look pristine after several years or begin showing signs of ageing far too early.

After all, speaker fabric has to do considerably more than simply allow sound to pass through unobstructed. It must remain evenly tensioned over time without sagging, be easy to install, resist fading, avoid lint formation, and cope reliably with everyday s

On New Year’s Eve, a nightclub in Switzerland catches fire. Just three months later, another nightclub near Strasbourg, in the Franco-German border region, is engulfed in flames. Coincidence? What links these incidents is less their specific cause than a structural vulnerability in fire safety concepts for public interiors. Against this background, the question arises: what meaningful contribution can our flame-retardant speaker cloth FR make?



In the night of 22 March 2026, several hundred people are gathered on the dance floor of a nightclub in Kehl when, within minutes, a scenario unfolds that feels disturbingly familiar. A fire breaks out at ceiling level and spreads rapidly across the space. Only a swift and well-executed evacuation prevents fatalities. Around 750 guests manage to leave the building, but large parts are destroyed and the structure cannot be saved.

The event inevitably recalls the disaster in the Swiss alpine resort of Crans-Montana, where around 40 people died and more than 100 were injured in a bar fire. According to investigations, a firework ignited the ceiling lining of the bas

Which standards and certifications provide meaningful insight into the quality, practical usability, and performance of a speaker fabric? The second part of our blog series “Acoustic fabric and standards” focuses on the parameters that allow a reliable assessment of the workability of speaker cloth.
 Which parameters and standards define workability?A speaker fabric must meet high expectations not only in terms of sound transparency. It should also ensure that speaker fronts, acoustically effective wall coverings, ceiling panels, and AV furniture look as refined as possible, while protecting the technology behind them from dust, particles, and contact. This requires a material that is both easy to work with and sufficiently durable.
 A key factor: elasticity in acoustic fabricsElasticity, or stretchability, plays a particularly important role in these applications. The more elastic a fabric, the easier it can be mounted with the right level of tension, for example on a frame. Single jersey fabrics offer a clear advantage over woven or braided materials, which are

Which standards and certifications provide meaningful insight into the quality, practical usability, and performance of a speaker fabric? Our blog series “Acoustic fabric and standards” offers a step-by-step overview of the key standards, their practical relevance, and the defining parameters for these technical textiles. We begin with the most decisive aspect: acoustic transparency.

 How is the acoustic performance of speaker fabric measured?One of the main challenges when seriously evaluating acoustic and speaker fabrics lies in the wide range of technical standards that are often cited without proper context. The majority of these standards originate from building acoustics and focus on sound absorption. As a result, they are only of very limited relevance when applied to acoustically transparent textiles.
 Missing the point: standards focused on sound absorptionA classic example is EN ISO 10534-2. This standard describes how the sound absorption coefficient of a material is measured in an impedance tube. It determines how effectively a material convert

Acoustic fabric is far more than an attractive outer layer for loudspeakers, audio and video equipment, as well as absorbers and diffusers. But which standards and certifications actually provide meaningful insight into the real-world usability and quality of such a technical textile? In our new blog series, you will find a comprehensive overview of the most important standards, their practical relevance and the key parameters involved.
 Clarity – not only in acoustic termsIf you look more closely at sound-transparent fabrics for loudspeakers, home cinema, studio environments, or AV furniture, you will quickly encounter a confusing array of standards, testing procedures, and certifications: frequency response measurements and air permeability, colour fastness, elasticity, flame resistance tests, splash water protection, quality assurance … everything appears to matter. Some of it is highly relevant in practice, while other aspects are almost curious footnotes.

Which tests actually tell you something about the practical suitability, safety, and protective function of a speaker fabric? How can you as

There are plenty of situations where sensitive audio components such as microphones or loudspeakers are used outdoors and not always under cover. That is precisely why we developed Speaker Cloth 2.0. Here, we explain what kind of protection it offers against rain and splashing water and why the idea of a fully waterproof speaker fabric simply doesn’t make sense.


Picture this: you’ve set up your terrace for a warm summer evening. The speakers are in place, the playlist is already running and then, quite unexpectedly, a brief shower passes through. This is where outdoor-ready speakers really come into their own. You can leave them where they are, knowing that a bit of rain won’t do any harm. A key element of such speakers is a water-repellent front fabric that allows raindrops to bead off the surface, protecting the delicate speaker membranes behind it. That is exactly the kind of application Speaker Cloth 2.0 was designed for.

At Akustikstoff.com we believe in fair prices, solid advice, high-quality materials and customers who prefer to make thoughtful decisions rather than being rushed by artificial scarcity. Here’s why we don’t run Black Friday promotions and why that ultimately benefits you.


As soon as November begins, the pre-Christmas shopping frenzy starts almost everywhere. Retailers push Black Friday, Black Week, Cyber Monday, Singles Day and an ever-expanding range of cleverly orchestrated sales events, each promising offers that are supposedly available only today, only now, or only for a few hours. You may well have caught yourself clicking on one of these “mega deals” and later wondered whether the offer was genuinely good or whether you simply gave in to the impulse of the moment.

Perhaps you have also felt fooled when you discovered afterwards that a product had quietly become more expensive a few weeks before the big discount event, only to reappear at a “super-saver price” that looked suspiciously similar to the original normal price.

We know these mechanisms all too well and view them with c

Since 9 October 2025, real-time bank transfers have been available free of charge at all banks within the euro area. That’s a major improvement for customers who either can’t or prefer not to use external payment services, but still want to receive their acoustic fabric as quickly as possible.


Whether for an urgent client project or a DIY weekend plan, most customers who order loudspeaker fabric from us want it in their hands without delay. One of our long-standing principles is that all orders placed in our online shop from Monday to Friday are prepared for dispatch as soon as payment arrives. In practice, this means that orders paid by early afternoon usually leave our premises the same day with our shipping partners.

But what if, for whatever reason, you’d rather not pay by credit card or via an external provider such as Paypal? When you select the "invoice/advance payment" option, you receive an order confirmation by email straight away. Yet a conventional bank transfer still takes time. Under EU rules, banks must ensure SEPA credit transfers reach the recipient’s account by the next business day —

Sound transparency is not the same as sound insulation. But although we only supply sound-transparent fabrics, these play a key role when it comes to improving rooms with sound-absorbing measures that are attractive yet effective. Here is an overview of how optimal sound insulation can be achieved with the right choice of materials in combination with Akustikstoff.


It often starts with a misunderstanding: “I am looking for a fabric that blocks sound for my home cinema. Which of your products should I choose?” Our response is usually another question: what exactly are you planning to do? This often leads to a detailed conversation, because when it comes to “sound-insulating fabrics” we are not the right place to turn. In fact, fabric is rarely the best material to reach that goal.What does Akustikstoff.com acoustic fabric do? People searching for sound-absorbing textiles usually want one thing: quiet. They want sound absorbed, reverberation reduced, unwanted noise minimised. That is not what our fabrics are made for. Akustikstoff.com fabrics are designed to let sound waves pass through as freel

Many suppliers like to present impressive graphs, but without knowing how to read them, those graphics say nothing. Sound transparency is a term that many promote, yet only those who know what truly matters can assess fabric reliably. In this article we explain which factors influence acoustic transmission, how to interpret typical measurements, and what really counts when you don’t want appearance to compromise sound.


When you search online for speaker fabrics, you often run into grand promises and plenty of snake oil, just as with any other aspect of speaker technology. Only reliable measurements matter. But which metrics actually count? What do all those numbers and curves really tell you? And which marketing claims are just empty noise?
 The fabric must play alongA top‑quality loudspeaker only delivers its full potential when nothing interferes between the diaphragm and your ear. But speakers are frequently covered for aesthetics, protection, or practical reasons. And as soon as whatever material comes between the sound source and the listener (or a microphone, absorber, or diffuse

You’d like to place an order in our online shop, but at checkout you’re told that delivery to your chosen country isn’t possible – or you can’t find your country in the dropdown menu at all? We’ll explain what’s going on and what you can do to get your hands on our sought-after acoustic fabric anyway.


“Hello, I’m looking to purchase 2 metres of your 2.0 water repellent fabric, but I am having an error when checking out. Are you able to ship to the United States?” Messages like this reach us regularly. And indeed: we’re unfortunately unable to serve every customer everywhere in the world. The reasons for this are varied, and the implications differ depending on the destination country. Here's a quick overview:
 Delivery within the EUAs a rule, we only ship to private customers within the European Union. However, the various national implementations of the EU Packaging Regulation have created administrative nightmares and cost traps that make it economically unviable for us to continue shipping to private customers in all EU member states.
