Econik 1851

Ceramic tweeters from Eton Audio

The Econik 1851 tweeter uses a high-precision ceramic system from Eton, a manufacturer that has been renowned for many years for its exceptional material expertise and particularly low-distortion high-frequency reproduction. The extremely rigid yet sensitive ceramic dome enables impressively clear reproduction of the finest details and guarantees exceptional resolution across the entire upper frequency range.

The high internal damping of the ceramic composite material effectively suppresses unwanted partial vibrations, resulting in a silky-clear, unadulterated sound image. The precisely tuned motor system contributes to a very low distortion structure and ensures exceptional impulse fidelity – even with demanding music passages and high levels.

The tweeter fits perfectly into the overall design of the Econik 1851 and offers brilliant, detailed high-frequency reproduction that impressively combines analytical clarity with musical smoothness.

Low-midrange speaker from the Arcosia series by Eton Audio

The low-midrange driver in the Econik 1851 comes from Eton's renowned Arcosia series and represents high-end engineering "Made in Germany". The characteristic Arcosia cone, made from a specially hardened composite material, combines high rigidity with excellent internal damping. This results in extremely clean, controlled decay and ensures neutral, precise reproduction in the crucial bass and midrange frequencies.

The carefully designed magnet system enables dynamic, differentiated reproduction of even the smallest changes in volume. The entire chassis design is geared towards high resilience, fast impulse processing and extremely linear performance – characteristics that offer audible advantages, particularly with complex music and high volumes.

Combined with the precise tuning of the Econik 1851, this results in a sound image of exceptional naturalness and clarity: voices come across authentically, instruments retain their characteristic structure, and the transition to the high frequency range is seamless and harmonious.

This flexibility makes it easy to integrate the speakers into any room concept and interior design, allowing you to design your music system or home cinema exactly the way you want it.

Future-proof technology

Through its ongoing development and improvement of transmission standards, WiSA is establishing itself as a future-proof technology. Owners of Econik speakers can rest assured that their systems will continue to meet the highest audiophile standards. Continuous innovation in the field of wireless audio transmission promises long-term compatibility and performance that meets the demands of modern audiophiles.

Highest signal purity and integrity

One of the key advantages of WiSA technology is its ability to transmit audio signals with a resolution of 24 bits and a sampling rate of 96 kHz, ensuring unrivalled sound quality. Unlike traditional wired systems, where signal quality can be compromised by resistance in the cables, wireless transmission ensures pure and unadulterated reproduction that is every bit as good as the original.

Minimisation of internal signal paths

The Econik 1851 features internally minimal speaker cables to minimise any losses and maximise efficiency. This internal design decision, combined with wireless transmission, ensures that the audio signal is routed directly to the speaker chassis with minimal interference. The result is exceptional fidelity and dynamics that are difficult to achieve in traditional systems.

At the heart of the outstanding sound experience offered by the Econik 1851 lies advanced technology that goes far beyond traditional audio concepts: the digital crossover. This innovative component is the heart of our loudspeakers and is responsible for the exceptional clarity and precision they deliver. By using specialised digital filters, in particular Finite Impulse Response (FIR) filters, the digital crossover achieves a level of detail and sound quality that previously seemed unattainable.

Precise frequency separation and optimal chassis control

The digital crossover separates the incoming audio signal into different frequency bands, each optimised for driving specific drivers, such as woofers, midrange drivers and tweeters. This separation allows each driver to reproduce only the frequencies for which it was designed, resulting in a significant reduction in distortion and an improvement in overall sound quality.

Thanks to digital processing, we can achieve a level of precision in frequency separation that is not possible in analogue systems. The digital crossover allows for extremely fine and precise adjustment of the filter characteristics, so that the transitions between the drivers are seamless and without audible discontinuities. This results in perfect harmony between the drivers, with each element of the audio spectrum reproduced with optimum efficiency and coherence.

The soul of active loudspeakers: the digital crossover in practice

A key feature of the digital crossover is its ability to control the time delay between the drivers to within a fraction of a millisecond. This precise timing ensures that the sound waves from each driver arrive at the listener synchronously, which is essential for maintaining phase coherence and creating a spatially accurate and three-dimensional sound image.

The digital crossover is therefore more than just a technical component; it is the soul of active loudspeakers, opening up a new dimension in sound fidelity. With its help, we achieve sound reproduction that sets new standards in terms of both precision and naturalness.

Overcoming phase problems through advanced digital signal processing

In the Econik 1851, we have overcome these challenges through the use of advanced digital signal processing. Our specialised digital crossovers enable accurate phase control that far exceeds the capabilities of passive systems. Precise digital algorithms allow us to ensure that the phases of the sound waves from each driver – whether it's the tweeter, midrange or woofer – are perfectly aligned.

This precise phase alignment is crucial because it allows the sound waves to combine into a harmonious whole instead of cancelling each other out or interfering with each other. Phase coherence is particularly important in the transition frequencies, where the acoustic contributions of the various drivers should blend seamlessly. In passive loudspeakers, poor phase alignment can result in an unclear sound image, as sounds no longer reach the listener at the same time. This can impair the sound stage and the localisation of sound sources, ultimately diminishing the overall listening experience.

The importance of precise phase alignment for a harmonious and detailed sound image

The Econik 1851, on the other hand, uses digital precision to overcome phase problems. The result is a coherent and integrated sound image that is so detailed and lifelike that it is as if you were sitting in the front row of a concert. With our technology, every musical detail is reproduced with extreme precision and without time delay, which is an unattainable luxury in passive technology. Phase coherence is therefore not just a technical specification, but the key to a natural, immersive and emotionally touching listening experience.

Digital purity: A new era without analogue components in the signal path

There are essentially two different approaches or philosophies for passive loudspeaker systems:

1. The first variant involves the use of many components to achieve a uniform frequency response. However, this complexity inevitably leads to undesirable side effects. Phase shifts and delays in the sound definitely occur, which makes the music sound unnatural and impairs playback.

2. Alternatively, a reduced number of components can be used in the signal path to minimise interference. However, this simplification inevitably leads to uneven sound, as not all frequencies are reproduced equally loudly by the chassis.

Our innovative technology goes beyond these traditional approaches. With our digital crossover, we not only achieve an even more linear frequency response compared to passive systems, but also completely avoid disruptive analogue components in the signal path. The result is a clear, precise and natural sound that combines the best of both worlds and takes the listening experience to a new level.

Stereo Hub and Surround Hub offer two options for sound correction: an automatic calibration system and manual EQ settings. These functions can be used independently or in combination to achieve customised sound optimisation.

Automatic calibration for perfect bass

The calibration system uses advanced algorithms to automatically analyse and adjust the bass range of your room. Targeted correction below 500 Hz makes the bass more precise, controlled and free of unwanted resonances or overemphasis that can be caused by room acoustics. The result is clean, tight bass that forms the basis for a clear and detailed overall presentation. This selective calibration process ensures that the room acoustics are precisely corrected where it is most needed without compromising the sound quality in the mid and high frequencies. This preserves headroom and does not restrict dynamics, which is particularly important at higher frequencies.

Manual EQ settings for individual preferences

The manual EQ settings allow you to customise the sound completely to your liking. With a selection of parametric, low-pass, high-pass, high-shelf and low-shelf filters, you can target specific frequency ranges. These settings allow you to change the sound character of your speaker and tailor it perfectly to your listening habits.

Three memory slots for individual manual settings

To further increase flexibility, you can save up to three different EQ configurations in presets. This allows you to quickly and easily switch between different sound profiles depending on what you are listening to or the mood you want to create. Whether for an intimate jazz concert, a dynamic film scene or relaxed background music, the storable EQ presets allow you to adjust the sound in no time at all.
