Nils Landgren about Concrete Audio N1
“Concrete Audio is not only refering to the material the speakers are made of but also to the sound, being just that, concrete. I have never in my life heard Chet Baker sound so good! If you are looking for concrete sound, check out Concrete Audio.”
Nils Landgren, musician & producer
Intention
We love music.
Authentic and crisp. Accentuated and rich in detail.
We are fascinated by sound.
To perceive instruments naturally, to feel every nuance. The breath of the singer. The sound of a string on the fingerboard. The movement of an ensemble on stage.
Pure, vivid and intense, our loudspeaker systems transport the complete sound spectrum into any space. Nuances are so tangible.
Because we love music.
We design and produce unique loudspeaker systems of timeless elegance and impressive dynamics. Made of concrete.
CONCRETE AUDIO® – The Loudspeaker Manufactory in Germany.
Material
Cement, sand, water
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 today has evolved into a high-tech product with highly varied 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 smooth surface resembles cut stone and can be sealed with oil, wax or polish. If desirable it can also be lacquered or real wood veneered.
Story
The idea of a housing made out of concrete came to us during a conversation between friends about the ultimate sound for loudspeakers. 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.
Our speaker systems are produced in a limited edition in Germany.
Each individual piece is being worked on until it meets requirements for the highest quality.
Why concrete?
Unlike the body of a musical instrument, good loudspeaker housing should not vibrate, as modern drivers (the actual loudspeaker in the box) today render the full sound spectrum linearly. But if the housing itself does vibrate due to its construction or materials (wood, plastic), then those vibrations affect performance by amplifying or diminishing certain sympathetic frequencies within the sound spectrum. It is a complicated physical process with a simple and clearly audible consequence:
The music does not sound original, it sounds distorted and unnatural. Here, the difference with musical instruments is clear. It is desirable that the natural resonant frequencies of a violin body should colour the instruments sound. It is only in this way that timbre comes to distinguish a Stradivarius from other violins. The only sound that should be heard from a good loudspeaker is the input signal, nothing more and nothing less.
Concrete is:
Very heavy.
Its weight and high density prevent it from vibrating.
Irregularly structured.
Vibrations can not spread.
Castable in any form.
It is possible to cast a very robust loudspeaker housing with one single pour.
We manufacture the housing of our loudspeakers made from high-strength concrete.
By means of a special casting process, the housing is cast out of one single body with all sides closed and sealed. The monolithic structure has no internal walls in parallel and is lined with different layers of sound absorbing materials to prevent any possible reflections. The result is a resonance free housing that lets the driver function as it is intended.
Music in its original form.
The F1 is an innovative multipurpose wall mounted loudspeaker designed for use in different spaces and to compliment interior design – Ultra flat, active and wireless.
Patented array-technique of the Fraunhofer IDMT – 41 electrodynamic mini-speakers act like one large
membrane, allowing for a total depth of only 32 millimetres and giving a convincing performance.
Audiofly Syncronice wireless
Audiofly HighEnd Wireless Audio – Listen to music in CD quality with a smartphone, tablet or streamer.
Enjoy synchronised sound from a TV or games console without delays.
Uncomplicated & individually
The F1 is simple to install and operate.
Decorative – Stand out with a pure concrete design or choose from a wide range of colours and surface finishes.
Discreet – Combine the F1 with aluminum or real wooden frames or add a reversible cover with individual motif.
Winner German Design Award
“This innovative product is a high-end loudspeaker made of concrete – flat as a picture, completely active and wireless. Concrete Audio combines an ultra-flat concrete body and the patented array technology developed by Fraunhofer IDMT in a single innovative loudspeaker system. 41 miniature loudspeakers work like a large membrane and deliver a convincing performance. Concrete has a strong inner dampening effect and is also very dense, and the two spell ideal acoustic properties. Purist elegance with cutting-edge technology.”

The N1 is a passive floorstanding loudspeaker designed for a completely natural sound reproduction without any loss of quality.
The housing of the N1 is cast with
a single pour, all sides are closed.
For reasons of sound we dispense
with bass reflex tuning. That’s how
we achieve outstanding low bass
with extremely low distortion factor
and precision at very high levels.
HighEnd
The high-end drivers, built into our systems, are characterized by absolute accuracy,
speed and fidelity. The signal path is equipped with a very small number of selected
components. We use a 6dB filter, fitted with copper foil coils and silver-gold
capacitors of very high quality as well as VOVOX Textura internal wiring. 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 – CONCRETE AUDIO N1

AUDIO about Cocrete Audio N1
„You’re allowed to fall in love with this speaker. It is exceptionally streamlined, from the crossover to the drivers. Even the finest, softest impulses are on point. The bass drops down astonishingly low and satisfies with strong-contoured presence. Altogether this speaker is as sensual as it is sensible. Smooth, coherent and big. A loud bravo to Weimar!“
