Church Organ With Acoustic Cloth From Akustikstoff.com

The field of application for our sound transparent fabrics is surprisingly broad. They also play an important role in organ building, for instance. It is quite possible that you will come across products from Akustikstoff.com when visiting a church, for example in Ahaus in northwest Germany. 

The pipe organ, whose roots reach back to antiquity, has played a central role in Christian liturgy since the Middle Ages. Elaborately designed organs are special treasures of numerous churches and impress with their enormous sound variety. Mozart once called the pipe organ the “king of instruments”. Like other instruments, however, organs need regular professional care and occasional restoration. For many parishes such a restoration project is a welcome opportunity to expand and redesign the instrument in order to broaden its musical range and move it closer to modern sound ideals. 

One example is the widely known Church of St. Mary’s Assumption in Ahaus, Germany: The local Catholic parish commissioned the old-established organ builder Orgelbau Fleitner from nearby Münster with extensive restoration and extension work. The task was to clean the old parts of the church organ, reassemble them, and make reasonable additions.

A particular challenge for organ builder and voicer Eberhard Hilse, one of the owners of Orgelbau Fleitner, was to harmoniously adapt the appearance of the instrument to the church interior, which dates from the mid-1960s. Hilse chose our acoustic fabric to implement a visually appealing design without compromising its sound and acoustics. 

Completed in February 2018, the three-manual instrument is 9.35 meters high and boasts the impressive total of 2,520 pipes: The swell at the top has 772 pipes, the grand organ in the middle has 840 pipes, the positive behind the console 728 pipes. In addition, there is the pedal with over 180 pipes. The largest pipes belong to the principal 16′, which can be seen at the front of the organ and is assigned to the pedal. The largest of these pipes in the front left with a total length of 664 cm has a diameter of 250 mm and weighs about 105 kg.

Tape Magic

How to use our self-adhesive hook fastener tape

A couple of days ago we received an email from Casper, a customer from Denmark: »Shouldn’t the fixing tape I received consist of two parts – one for the fabric and one for the cabinet?« To get straight to the point, his assumption was wrong. But Casper was completely happy with the product after we’d emailed him a few explanatory lines and a link to our video tutorial. So, what’s the secret of our fastening tape?

Just like Casper, most people are under the false impression that hook fastener tapes always consist of two components, a strip with tiny hooks and another one with soft loops. This is true indeed for the classic »velcro« as we know it from numerous everyday applications, which is called a »hook and loop fastener« (there’s even a lengthy article on Wikipedia for those who are interested). In our case, however, you won’t find a single hook under the magnifying glass. Have a look at the closeup photo and you’ll find that the upper side of the fixation tape is covered with small stalks that have a mushroom-like top.

To mount the speaker cloth, simply press the fabric onto the tape. Best protect your fingers with a robust glove or use something like a wallpaper roller, as the little heads are quite hard and edgy. They will penetrate the mesh and keep the speaker fabric in place tightly. Our video tutorial on Youtube provides you with more detail.

Mounting speaker cloth

The great advantage of this mounting method is that the speaker cloth can be detached again if you ever feel like giving it a wash or replacing it with a new piece of Acoustic Cloth in another colour.

»Color of the Year 2020« An Ageless Classic Blue

Trust, hope, peace, and tranquility are properties that are traditionally associated with the colour blue. No great surprise, then, that the Pantone® Color Institute has made a very classic, neutral blue the “Colour of the Year 2020”. After all, our life feels considerably more turbulent than a decade ago: Megatrends such as digitisation, along with political and social upheaval around the world, are contributing to a general longing for harmony and security. 

The calm, appealing, and confidence-inspiring deep blue colour of the year 2020 “lends itself to relaxed interaction. Associated with the return of another day, this universal favorite is comfortably embraced” says Pantone, explaining the choice of the colour that is expected to shape fashion and beauty as well as interior design and the design of electrical and electronic devices worldwide for the next twelve months. At Akustikstoff.com the colour of the year is available as “Navy Blue”.

When it comes to loudspeakers, “Navy Blue” spontaneously brings to mind JBL’s classic 43xx and 44xx studio monitors. These treasured vintage speakers still have a firm place in many studios and we have recently supplied the speaker fabric for countless refurbishment projects all over the world – evidence to suggest that blue speaker fronts will see a renaissance in loudspeaker manufacturing in 2020. 

Navy Blue, a particularly calm, balancing, and attractive hue, is a good choice for interior design purposes as well: It can be combined with black and white as well as with silver, gold, and numerous organic brown hues. 

Acoustic Cloth in Navy Blue is available as Standard speaker cloth (colour code 38), as water-repellent and stain-resistant Acoustic Cloth 2.0 (colour code 138), and as non-flammable Acoustic Cloth FR (colour code 238), which is particularly suitable for projects in public spaces.

Spray Adhesive as a Problem Solver

Many hifi enthusiasts have developed a great passion for the DIY refurbishment of vintage speaker cabinets. An update of the speaker grille with new Acoustic Cloth is one of the key elements in most of these projects, but it’s not always the easiest task. 

The JBL* LX55, for instance, a popular speaker among experts that is sold at increasingly high prices today, has a plastic frame with a relatively small edge to which the original speaker cloth is attached to. Moreover, the slot between the frame and the cabinet is extremely narrow. This construction makes it impossible to staple the speaker fabric to the frame (the method of choice with wooden frames) or to use of hook fastener tape instead. 

This is where our special spray adhesive comes into play. The adjustable nozzle of the container ensures convenient and economical application of the adhesive without any scattered spray mist and the high immediate adhesion of the adhesive provides for the easy and precise mounting of our sound-transparent fabric on such frames. It’s the perfect solution whenever you want to make speakers with plastic frames look like new.

»Your adhesive is really good for mounting fabrics. Very easy to use, no spill, and good adhesion. I used it for my JBL LX55 speakers with your grey cloth (colour code 14). I also refurbished a pair of Bose* 601 series 1 speakers with your beige fabric this year and I am perfectly happy with the result«, wrote Emmanuel D. from Digoin in France as he proudly sent us some photos of his speaker refurbishment projects.

DIY Embellishment: Covering AV Furniture With Acoustic Cloth

Sometimes it’s the little things that make small rooms look friendlier, less cluttered, and more attractive. That’s why it is a good idea to cover the often small-sized compartments of an AV rack in such a room with Acoustic Fabric in a matching colour. The immediate effect is that the entire room appears more straightforward and comfy.

Making such a cover doesn’t require any distinct DIY skills. All you need to build is an accurately fitting wooden frame with a hinge and a magnetic catch. Cover this frame with an appropriately sized piece of Akustikstoff.com Speaker Cloth (watch the tutorials on Youtube for details) and you’re done. The Acoustic Cloth lets infrared signals pass easily, so remote controls for receivers, amplifiers, etc. will work through the closed front, while all equipment along with the centre speaker or a soundbar remain hidden – as well as the countless little thingies that inevitably tend to accumulate in such a shelf over time.

MC Audiotech chooses Akustikstoff.com as OEM supplier

MC Audiotech is a new name in high end audio, but the people behind the company and the products are not. With over 60 years of combined experience in the high-end audio industry through Linaeum, Impact Technology, and Veloce Audio plus an array of patents that speak to true innovation under their belt, they are driven by the true passion to develop trendsetting products that serve both the needs of most demanding customers and the music. 

The company, which is headquartered close to Philadelphia in the U.S. state of Pennsylvania, now offers a brand-new speaker system, the »Forty-10«. MC Audiotech say that this speaker truly »mirrors the sound of real-world voices and instruments«.

A brief summary gives a hint at this amazing speaker’s characteristics:  The »Forty-10« is a two-way design consisting of in-house designed and built proprietary transducers mounted in a double-curved so-called »spaced array™« and a separate »folded cube™« low frequency enclosure. 

MC Audiotech claim that their system is so efficient that can be driven by as little as 15 watts from the softest pianissimos to the most massive crescendos and is seriously full range, treating the lucky owner to a complete presentation of the recorded information, regardless of genre.

»Forty-10« speaker by MC Audiotech

Visually, the speaker is an elegant nod to mid-20th-century modern design. By default, it comes in a satin walnut veneer with bright aluminium work and grille covered with Akustikstoff.com’s off-white speaker fabric. Other options for material and finishes are available. One example is the Figured Maple option which is paired with black metalwork and beige speaker cloth from Akustikstoff.com.

We are delighted to have contributed to the creation of this wonderful product with our Standard Speaker Cloth. The »Forty-10« by MC Audiotech gives further proof of the fact that the quality of our fabrics meets even the highest demands of proven high-end professionals.

Simply Great: Individual Speaker Cloth Pre-Cuts

Speaker cloth laser pre cuts by Akustikstoff.com.

Quiz question: What does our boss present in this photo? A new, even more sound-transparent speaker fabric? Nice try, but not even close! Such grids remain when we produce individual pre-cuts of our speaker cloth.
Manufacturers of consumer electronics, AV furniture, vehicle components, and even slot machines are increasingly relying on such laser-cut pieces of our speaker fabrics produced exactly to provided standard CAD data.
As required MOQs are extremely small and lead times are next to none, Akustikstoff.com pre-cuts are also worth thinking about for companies that only produce very short production runs: Any tedious – and in most cases little precise – cutting of the fabric on the shop floor is eliminated, the pre-cuts can be processed immediately. On request, we can even “engrave” the speaker fabric, for example with a product name or a company logo.

Acoustic Cloth 2.0 for Italian High-end Sound Studio

»The Spheres« is a recording studio and events space in Pescara-Montesilvano (Italy) on the Adriatic coast, offering state of the art audio and video equipment as well as an active concert calendar. Without doubt, the studio, which also offers mixing and mastering services along with outstanding recording opportunities, can be considered one of the finest recording studios in northern Italy and even beyond – especially for classical, jazz, and world music. It is available to all labels, engineers, projects, and artists who want to benefit from the extraordinarily high levels of acoustic and technical standards that characterize the studio throughout.

Main room of

The studio was designed principally for acoustic music, but is versatile and welcomes all genres. It was rapidly constructed inside an adapted warehouse between November 2016 and May 2017. Planning and acoustic design was by producer, sound engineer, and studio owner John Anderson. The classical pianist, who runs the record label Odradek Records, holds two performance degrees from the Accademia Musicale Pescarese and a degree in musicology from the University of Oxford. 

Having had a look at samples of our Acoustic Cloth 2.0, John decided to use this stain-resistant, liquid-repellent, and B2 fire-rated fabric for the numerous wall and absorber covering purposes in the recording rooms and the control room of his studio. Altogether, 160 square metres of Acoustic Cloth 2.0 and 250 metres of our adhesive hook fastener tape were used in the construction of »The Spheres«.

Main room of

The main room offers 135 square metres of space and a diffuse sound field that is achieved with eight 2D QRD »Skywalker Sound« replica movable diffusors/gobos, and a further 144 2D QRD »BBC style« diffusors mounted on the walls. Every corner has a wedge bass trap from floor to ceiling, a column of 115kg per cubic meter dense rock wool covered with Acoustic Cloth 2.0, which help control the room’s bass build-up and modal distribution. The dropped ceiling is sound absorbent. The floating walls are insulated and isolated via rubber decouplers from the structural walls behind. The result is a silent, world class lively ambience with no boomy bass build-up confusion and silky-smooth highs with no harsh flutter echoes.

Control room of

The control room features 48 square meters with four-metre ceilings and has a separated machine room. It is a Tom Hidley »non-environment room«-inspired design with vertical and horizontal wave guides angled to capture incoming sound from their opposite side monitor. Sound is trapped by eight cm of dense rockwool behind. Unabsorbed energy is directed away from engineer’s listening position to create a reflection free space, ensuring accurate monitoring. The waveguides are completely covered by Acoustic Cloth 2.0 for an elegant finish.

Colour Trend 2019

A lively, warm and gentle tea rose hue has been designated the »color of the year 2019«. It »appears in our natural surroundings and at the same time, displays a lively presence within social media«, explained color specialist Pantone LLC as they presented their choice, which they decided to call »Living Coral«.

Presumably Strong Trend
The color of the year 2018, a bold, bright, and somewhat pompous violet referred to as »Ultraviolet« didn’t really catch on. For the much more harmonious tea rose hue »Living Coral«, chances are expected to be much better. It is expected to become a dominant trend in fashion, consumer goods, and even interior design next year. The trend was already looming on the catwalks lately. Tea rose and coral hues are playing an important role in spring fashion from Prada, Hermès, Brandon Maxwell, and Giambatista Valli for instance, while Calvin Klein, Moschino, and other fashion labels already used them in their 2018 fall collection.

Always on trend in 2019 with speaker fabric from Akustikstoff.com in «Tea Rose«

Sound-transparent Fabrics in the Colour of the Year
Speaker cloth from Akustikstoff.com in Tea Rose keep you well prepared for the upcoming trend. The colour is available as a Standard Acoustic Cloth (colour code 35), as water-repellent and stain-resistant Acoustic Cloth 2.0 (colour code 135), and as nonflammable Acoustic Cloth FR, which is particularly suitable for public buildings (colour code 235).

Design Hints
Tea Rose can be harmoniously combined with many colours – another big difference to last year’s somewhat conceited violet. It comes especially nice when combined with speaker fabric in Pastel Blue (color code 34) – a combination that creates the positive, maritime yet warm color play of a coral reef, to which Pantone themselves refer in their video for their color of the year 2019. Artichoke (47), Navy Blue (38), Light Ochre (20), Off Yellow (21), and Green Tea (40) also make for attractive, warm, summery combinations.

Play it Safe With Acoustic Cloth FR

We raise the bar for sound-transparent fabric again: Our new Acoustic Cloth FR is non-flammable and will fulfil the dreams of many architects, interior designers, stand builders, and PA techs.

It’s a speaker cloth the world has been waiting for: Flame-retardant, easy to work with and elastic, with excellent acoustic and aesthetic properties,  available off the shelf in numerous attractive colors. Our newly developed Acoustic Cloth FR makes the world of sound-transparent fabrics significantly better.

Akustikstoff FR ist nach NFP 92502 als nichtbrennbar (M1) zertifiziert.The renowned French test institute FCBA has certified Acoustic Cloth FR to be nonflammable according to the European standard EN 13773-1 as well as to the much more demanding French standard NFP 92503 M1. It puts an end to a notorious problem that bothered architects, interior architects, PA and event technicians day by day: So far, applicable fire protection regulations and the use of visually attractive, sound-transparent fabric in publicly accessible buildings didn’t go well together.  Sound-transparent, visually appealing speaker fabrics  are usually made of flammable plastic fibres. But building codes and other regulations—as well as technical guidelines that are part of many contracts—require fabrics to be certified at least fire retardant (FR)  according to EN 13773-1.

For the first time ever, this dilemma can be considered solved. Our non-combustible Acoustic Cloth FR combines optimal preventive fire protection and outstanding acoustic properties and is available in 42 different colours right off the shelf with no lead time. The nonflammable (M1) speaker cloth exceeds the fire retardancy requirements that are part of most tenders. According to the FCBA test results, it’s about as combustible as plasterboard.

Whether used as speaker fabric or in decorative applications that require acoustically transparent fabric: Acoustic Cloth FR enables optimum fire protection without compromising on sound transparency in architecture and interior design as well as in exhibition booth building, stage building, shop construction, advertising technology, and at exhibitions, concerts, and events—and last but not least in the entire catering sector.
