When speakers disappear ...
... and Lifeklang remains.
Imagine your speakers had disappeared and you were sitting in a concert hall – that's how speakers with exclusive Vortex HiFi technology sound.
How do speakers disappear if we can't try Harry Houdini. The solution is: through imagination or, better still, imagination. But you could also say correcting the wrong loudspeaker signal through learned structures.
The main finding is that in hi-fi stereo the speakers and the room always give us incorrect information about the placement of the performers. Only the correction of the extremely wrong acoustic signals in the ear canal due to the head-related transfer functions (HRTFs) by the brain results in a listening experience that feels right for you and creates goose bumps and rocking of the foot.
Turning or tilting your head (by about 30 degrees) alters the sound in the ear canal by up to 20 dB. Similarly, a deviation of about 30 degrees between the virtual sound source and the real one (the loudspeaker) leads to inaccurate frequency responses of up to 20 dB. This is simply a fact of life in hi-fi stereo applications! And this doesn't even take the room acoustics into account, only the human head and its individual HRTFs. Therefore, phase and frequency responses can never be corrected by a measurement system!
But why is it possible to hear three-dimensionally in perfect rooms with perfectly tuned systems, even though every loudspeaker tells your ear: “the singer, the piano, the cymbal and the organ come from me”.
The answer is that the brain has to find out its truth and impose it on the real acoustics - i.e. replace it. But this requires an extremely efficient nervous system!
However, recent research shows that the nervous system is disturbed by alternating fields (Dirty Power Problem) , especially above 2.000 Hz, and that stress is created.
It is precisely these fields that we generate to an extreme degree through the crossover network, the cabling and, above all, through the sound transducers themselves (e.g. the coils of the tweeters), which generate sound by generating a high-energy field in conjunction with a membrane.
Studies show that the interference fields worsen perception
In order to investigate the influence of the interference fields of a loudspeaker on perception, we have devised a large number of experiments.
The graphic below shows the spectrum of an electric field emitted by a tweeter. The green curve shows the E-field without a signal (essentially mass disturbances). The red curve shows the E-field with a noise signal. A drastic increase in an electric field can be seen, even though it is a magnetic field generated in the voice coil. But electric and magnetic fields are mutually dependent.
Through intelligently applied earth potentials, we were able to reduce the radiated field to the blue curve.
Although there was no change in the signal, the sound quality improved extremely in the areas of sharpness, spatiality, image and richness of detail.
Systematically reduce the disturbances
1. Solution optimize speaker cables
The loudspeaker cables are themselves antennas and therefore emit interference from the amplifier. On the other hand, they pass the ground interference of the amplifier on to the terminal, the internal cabling, the crossover and all loudspeaker chassis.
The two pictures below show field strengths with a phase tester with the loudspeaker group switched off (ground connection only) as with the phase of a mains socket. The interference fields are not only visible on the loudspeaker terminal (left picture) but also on the chassis (right).
Our speaker cables with Distortion Field Absorber technology offer the perfect solution . This technology binds interference by grounding each conductor, drastically reducing the radiation of the interference field (see spectrum analysis, image below). As the E-field measurement shows, the Distortion Field Absorber technology significantly reduces the radiated interference fields. Yellow line: without Distortion Field Absorber ; red line: with Distortion Field Absorber . Our Distortion Field Absorber speaker cables are available from €1.200 per pair.
Our cables without Distortion Field Absorber technology are equipped with our Nano Shield shielding at the connectors. This shielding provides protection up to 40 GHz and absorbs the energy of high frequencies. A semi-precious stone containing our AIO information is embedded in the connectors for further interference and stress reduction . These Nano Shield coaxial speaker cables cost €499 per pair.
If you don't want to use our speaker cables, you can also suppress interference at the interfaces using our AIO Ronde 30. The AIO Ronde 30 costs €29 per interface (for orders of 10 units).
Our 2D interference suppression chips offer the most cost-effective solution . For just €2, you can suppress interference on one interface . The chips are simply glued onto the connector or terminal.
2. Optimize the speaker crossover solution
The crossover also emits interference fields. Since it is generally not shielded and cannot be shielded, the emission of the potential vortices described by Prof. Dr. Ing. Konstantin Meyl must be reduced. We have developed our AIO interference suppression products for this purpose . These products contain a field (bipolar active field), information for reducing the potential vortices (interference suppression), and for reducing stress in humans (stress relief). The interference suppression information is radiated into the loudspeaker by the active field and can thus neutralize the interference in the frequency crossover.
If you have a large crossover and want maximum interference suppression, we recommend our AIO Ronde 70. If the crossover frequency is located directly behind the speaker terminals, an AIO Ronde 70 can be positioned from below or from the side, affecting both the crossover and the speaker terminals. In this case, the AIO Ronde 30 or the 2D interference suppression chips are unnecessary. The AIO Ronde 70 costs €118.
A more economical solution for interference suppression of the crossover is the AIO Ronde 30 , which is best positioned on the side or below the crossover. An AIO Ronde 30 costs €29 per unit (for orders of 10 or more).
If you remove the crossover, you can also install 2D interference suppression chips . You can glue 6mm 2D interference suppression chips to the ground potential of the coils and to the capacitors. The price per 6mm 2D interference suppression chip is €2 (the chips are sold on a card of 50).
3. Optimize the loudspeaker chassis solution
The speakers' magnets and voice coils generate very strong interference. The loudspeaker chassis move precisely because of their fields. Every investment in strong interference suppression agents is worthwhile here.
One option is interference suppression using an AIO Ronde 70 , which is positioned under the loudspeaker, at the front of the baffle. The aim is for all drivers to be covered by the Ronde 70's focused field, which, like the beam of light from a flashlight, emanates upwards from the Ronde's surface. The AIO Ronde 70 costs €118 per unit.
Biologically, the most significant interference fields are those with frequencies above 2.000 Hz. These should therefore be particularly well suppressed. One possibility is suppression using an all -in-one (AIO) pyramid placed on the front edge of the speaker baffle. The pyramid should be positioned so that its base is above all the drivers. This ensures that the AIO pyramid effectively suppresses interference from all drivers.
The AIO pyramids cost € 49 for the 30mm pyramid and € 89 for the 40mm pyramid each.
The perfect solution is to use both the AIO 70 Ronde under the speaker and the AIO Pyramid on top of it. The correct polarity of the interference suppressors is crucial. For more information, please refer to the AIO Pyramid's instruction manual regarding bipolar active fields.
Our 6mm 2D interference suppression chips offer an affordable solution for driver interference . These are attached to the center of the driver on the diaphragm, and in the case of tweeters, on the mounting plate below the diaphragm – do not stick them directly to the tweeter diaphragm. Tweeters are typically extremely sensitive.
ATTENTION - Before you stick the chips on the membrane, ask the dealer or manufacturer whether this could damage the membrane! It is best to have the chips attached by a professional.
The weight of the chips will not affect the functionality of the chassis.
The price per 6mm 2D interference suppression chip is €2 (the chips are sold on a card containing 50 pieces).
