AUDIO SYSTEM

Clear sound.
Classic design.


For over ten years now, Gerd has been working on creating loudspeaker systems and amplifiers for the most demanding requirements of mastering and sound studios. He discovered early on the potential of electron tubes and highly efficient professional audio drives mounted in high-strength aluminum enclosures. And the technical foundation for ART DÉCO ACOUSTICS was created: a focus on the absolute minimum number of essential components, all of the highest quality.

» Art Déco provides the perfect framework for sound. «

Gerd wanted this simplicity and efficiency to be reflected in the system’s look as well. This is why he began looking for a design to support the speakers and amplifiers and help it achieve the best possible playback. He found what he was looking for in the Art Deco era: Timeless forms, classy materials and sensual elegance create the perfect framework for extraordinary sound.

The result: Gerd Köck's ART DÉCO ACOUSTICS audio system that redefines sound and design.

MONITOR

Almost spherical.
For perfect sound.


The monitor loudspeakers can be individually positioned to enable the audio system to create outstanding immersive sound without the interference of resonances. This results in a linear frequency response that is reflected in an exceptionally transparent sound quality.

Spatial resolution at its best

The playback frequency of the monitor ranges from 500 Hz to 22 kHz.

Phase and angle correction

By means of the integrated enclosure design, the midrange driver and high-frequency tweeter form a virtually perfect point source.

No secondary acoustic emissions

thanks to the edgeless, high-strength milled aluminum loudspeaker enclosure.

M24 Monitor Loudspeaker

For an interference-free playback of 500 Hz in the transition zone, the enclosure emission axes of both the monitor and the bass are at the same height despite being in separate enclosures.

BASS

Strong bass. Spacious
and transparent depths.


The sleek enclosure of the bass loudspeakers is adjusted both optically and acoustically to the monitors. The bass loudspeakers develop a powerful and transparent bass response. The woofers excel with a high degree of linearity over nearly five octaves. Distracting resonances have been consigned to history through exquisite attention to design detail.

Base for immersive sound

The bass suppresses vertical resonances by means of the enclosure design.

No secondary acoustic emissions

thanks to the edgeless, high-strength enclosure. Integration of the woofer and bass-reflex openings in an edgeless front panel with all-round braced plastic rear panel.

B24 Bass Loudspeaker

Since the bass and the monitor are kept separate per channel, they can be set up in an ideal way in any room. This makes for incredible spaciousness and transparency.

CUSTOMIZATION

Tonality.


This ensemble always hits the right note. Whether in a polished or painted finish: the high-quality aluminum surfaces integrate perfectly into your installation space. As an alternative, they can add a definitively stylish touch.

One of a kind

The paint finish is available in all RAL colors and metallic shades. For bass and monitors, the base plates, front and rear covers or body and stand tubes can also be designed in different colors. A combination of painted and polished surfaces is also possible.

LOUDSPEAKERS

Ideal team player.


Playback in unison. Optimized phase response.

The bass is in half space, separated at 500 Hz with the monitor in full space. This allows both loudspeakers to be positioned freely in relation to the wall.

Side walls

with dished vertical grooves to disperse secondary acoustic reflections.

Passive crossovers

with third-order filters and impedance linearization. High-quality film capacitors and shielded inductors of premium design. Signal latency significantly below Blauert and Laws criterion with smooth course.

Highest quality

and high efficiency of the audio drivers: No audible frequency modulation with small driver excursion.

Thermal fuse

and ultra-fast power limit circuitry of the loudspeaker to prevent overload damage.

AMPLIFIER

Clear structure.
Intense power.


The heart of the audio system is a stereo push-pull amplifier. Six electron tubes, symmetrically arranged, unfold their full potential. The result is a maximum level of linearity and fidelity with an open, transparent sound. Hissing and ambient noise are a thing of the past.

Inaudible ambient noise

Thanks to the use of electron tubes in an optimized symmetrical arrangement and a separate external power supply unit, maximum interference suppression is achieved.

Edgeless milled enclosure

The side walls have dished vertical grooves to disperse secondary acoustic reflections.

E25 Integrated Amplifier

Headphones can be plugged directly into the amplifier parallel to the loudspeaker outputs. The amplifier constantly self-checks for wear and sends an alert when changes become necessary.

Stereo push-pull amplifier based on electron tubes in an edgeless milled aluminum enclosure · Dimensions: width 51 cm, height 31 cm, depth 31 cm · Stereo sound: 14 – 50 W output power per channel (6L6 – KT170) · Frequency response < 12 Hz to > 25 kHz +/- 3 dB · Four analog stereo inputs, 3‑pin XLR · Speakon speaker outputs, 4‑pin: Two 4‑/8‑ohm outputs adjustable per channel

AMPLIFIER

Electron tubes
taken to the next level.


Fully symmetrical design

with triode preamp and ultra-linear pentode power stage. There are only 11 components per channel in the signal path and low local negative feedback in the preamp and power stage.

Fine attenuator

in the preamp.

Digital control

Supervision, control and remote control with microprocessors, separated and shielded from the audio component. Adjustment of the quiescent currents of the electron tubes and constant checking for short circuits with the option of shutdown in the event of a fault.

Elegant protection

of the electron tubes by means of removable, anti-reflective borosilicate glass tubes and additional protection with automatic shutoff when a tube is removed. This makes it easy and safe to change the electron tubes.

Galvanic isolation

of audio paths with input and output transformers.

External power supply

for worldwide use with supervision of primary voltage, current and frequency as well as internal voltages and currents.
