Concrete Audio - Elegant Speakers Made of Cement, Sand and Water.





Concrete Audio is a Loudspeaker factory in Germany whose founders love music. They design and produce unique loudspeaker systems of timeless elegance and impressive dynamics - housed in, you guessed it, concrete. These speaker systems are produced in a limited edition in Germany.




The following information is from their website:
The Materials


Cement, water, sand are the essential ingredients of a material whose recipe was already known during the Roman Empire - concrete.



Refined by a variety of additional ingredients, concrete in modern times has evolved into a high-tech product with highly varied properties and applications. Resilient, durable, and pourable into almost any form and especially, largely resistant to vibration.

Concrete forms, by its very nature, the perfect base for the housing of our loudspeakers.



The curing process makes each a unique loudspeaker - identical in shape and surface quality, but individually in terms of the grain.

The surface provides for several options of sealing to emphasize the natural feel of the material.

The Idea


The idea of a housing made out of concrete came to us during a conversation about the ultimate sound for loud-speakers. We concluded: concrete is perfect yet hard to restrain. Thus an equally elaborate and passionate experiment began, executed and carried out by superb hand-craftsmanship and attention to detail.



After several years of development and numerous test runs, we finally found the ideal solutions for the design of the mold, the construction and the special mix of the materials and founded the Loudspeaker factory Concrete Audio.



The design of the model N1 consistently meets functional requirements without neglecting the demands of a timeless, aesthetic use of forms.

Each individual piece is worked on individually until it meets requirements for the highest quality.

The Sound
The sound of a loudspeaker driver (sound generator) decisively depends on the quality of the loudspeaker housing.



Unlike, for example, the body of a musical instrument, a good loudspeaker enclosure should not vibrate because modern high-performance drivers operate linearly, reproducing exactly the sound information, which electrically has been transmitted to them.

Commercial housing made of wood or plastic, have their own resonant frequency. Yet at certain points of frequency bands, the housing starts to oscillate, i.e. vibrate, and thus reinforcing exactly that particular frequency. Additionally, this phenomena forms integer multiples of this particular frequency creating additional vibrations (overtones). This facilitates unnatural changes of the overall frequency spectrum. The result is a distorted sound by means of basically, a flawed housing.

We manufacture the housing of our loudspeakers made from special concrete with a compressive strength of at least 30 N/mm². This is harder than conventional concrete curbs. The amorphous structure and the high specific gravity of this material reliably prevents oscillation of the housing. By means of a special casting process, the housing is cast out of one single body with all sides closed and sealed.



This monolithic structure is lined internally with different sound-dampening material made of tightening yet elastic layers to prevent any reflections.



For reasons of sound, we build our housing completely sealed and without a bass reflection-tuning. This way, we achieve an extremely low factor of distortion and superior accuracy even at very high levels.

The drivers, or undercarriage used, in addition to the characteristics of the housing, determine the quality of the loudspeaker-system decisively.

We use the Scan-Speak drivers.
The Danish company Scan-Speak is known worldwide for its high level of innovation and uncompromising quality. Their high-end drivers, built into our systems, are characterized by absolute accuracy and fidelity. This allows us to equip the signal path with a very small number of selected components. We use a 6dB filter of very high quality, fitted with copper foil coils and silver-gold capacitors.



The result is a largely loss-free signal path and a very direct control of the linearly coordinated and selected pairs of precision-drivers. Combined with our high-strength concrete housings, we produce a high quality loudspeaker system –

The Timbre Speaker by Casey Lin




21 year old Casey Lin is working on her Bachelor of Design Innovation at the Victoria University of Wellington. With a Bachelor of Architectural Studies already under her belt, the New Zealand based Chinese designer is primarily focused on product design, with a special interest in furniture, jewellery, lighting and household electronics. One of her most recent projects is the Timbre Speaker, an unusual design I wanted to share with you.




Timbre Speaker trims the essence of a speaker down to the very bare minimum, allowing the inherent qualities of the materials to become the centerpiece of the design. All superfluous detail is stripped away, leaving only the necessary audio and power ports at the rear, and combined power and volume dial.



Wood and glass were selected for their favourable acoustic qualities which enhances the audio experience of the user. The Black American Walnut wood adds a warmth to the tone, while the addition of the glass vessels bring a more reverberant characteristic to the music.




Surface transducers are mounted on the interior of the wooden box, vibrating the surface and turning the box into a speaker. The glass vessels act as physical equalizers, where the vibrations transfer through the wood into the glass and changes the timbre of the sound. The wooden box can act as a standalone speaker, or alternatively, vessels of other material, size or shape can be placed on the speaker to change the sound according to the users taste.



Timbre Speaker has an elegant, yet playful feel to it, users are encouraged to experiment with different objects and placements to find the timbre they enjoy the most.

A Case Of Bass. Vintage Suitcases and Train Cases Turned Into One of A Kind Speakers.





In March of this year, the Cimino-Hurt brothers decided to launch A Case Of Bass, combining two greats: vintage electronics and vintage luggage, to make super sweet boomboxes. While not the first to do this (I blogged about a similar company named BoomCases years ago), these are significantly more affordable.


above: The Cimino-Hurt brothers combine 'tude and talent

The Portland-based company, A Case of Bass, creates portable sound systems hand-built to ensure quality and craftsmanship. Each "Case of Bass" is created after scouring the world for the finest unique vintage suitcases (train cases, brief cases and make-up cases, too) and then pairing them with a selection of speakers that guarantee the best combination of sound and aesthetic.

The Burlap Banger:

The Champ:

The Starflight:

Bunny:

Nicky29:


The cases incorporate - to your specifications - the types of accessories that will make your case unique to you. These include input types, amplifier sizes, power supplies and batteries, and finally any personal detailing you might desire.

Cecille:

Sam:

Marcelle:


In partnership with local Portland businesses, artists, and craftsmen they create these one of a kind portable parties.

Up-cycled and Sustainable
Sustainability, for those at A Case of Bass, means taking materials and designs, into which great amounts of energy have already been committed, and re-purposing them to extend that investment. It’s not recycling, where objects are stripped into the basic materials and then smelted back into something else. It’s up-cycling, where things are given new life and expected to be passed on or designed to be completely usable for something else without the need of deteriorating initial energy investment.

Staxx:

Candy:

Scooter:


Because the brothers want to give universal access, they do things like sell their products at an affordable price and make an eighth inch input standard on all of the cases. They use some new electronics, but only when they can’t find a reliable substitute from their rescued electronics. When providing things that have great environmental and economic impact implicit in their construction, like batteries, they strive for low impact, long life, and of course, rechargeable systems. At present they offer lithium ion rechargeable packs that are lightweight, high capacity, and high efficiency.

Midas:

Ruby the Riveter:


Finally, to demonstrate the overall sustainability of each case, they give a percent by mass of up-cycled material for each case. This is a process and they don’t profess to have all the answers but are working to continuously improve the quality of each case as an environmentally and socially responsible piece of electronics.
