When speakers disappear ...
... and Lifeklang remains.
Imagine if your loudspeakers have disappeared and you are sitting in the concert hall - this is how loudspeakers sound with the exclusive ones Vortex HiFi techniques.
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 your head (approx. 30 degrees) or tilting your head changes the sound in the ear canal by up to 20dB. A deviation of the virtual sound source from the real (loudspeaker) by approx. 30 degrees also leads to incorrect frequency responses of up to approx. 20dB. But this is always the case in hi-fi stereo practice! Not even the space is taken into account, just that human head and his individual HRTFs. Therefore, the phase responses and frequency responses can also nie be corrected by a measuring 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, the latest research shows that precisely the nervous system is affected by alternating fields (Dirty power problem), especially above 2.000 Hz is disturbed and stress arises.
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).
The perfect solution is ours Speaker Cables with our Distortion field absorbers - Technology. The interference is bound by an earth potential in each conductor and thus the radiation of the interference field is drastically reduced (see spectrum analysis, picture below). As the E-field measurement shows, the Distortion field absorbers - Technology clearly shows the radiated interference fields. Yellow line without Distortion field absorbers, red line with Distortion field absorbers. Ours Distortion field absorbers - There are speaker cables 1.200, - € the couple.
Our cables without distortion field absorber technology are in the connection areas with ours Nano Shield Umbrella equipped. This shields up to 40GHz and absorbs the energy of high frequencies. In the plugs there is a semi-precious stone with ours AIO Information for further Interference suppression and Stress relief. These cables the Nano Shield coax speaker cable cost 499, - € the pair.
If you don't want to use our speaker cable, you have the option of connecting your cable to the interfaces via ours AIO round blank 30 to suppress. the AIO round blank 30 costs 29, - € per interface / piece (for a purchase of 10 pieces).
The cheapest way of eliminating interference is ours 2D interference suppression chips Here you can get an interface for 2, - € suppress. The chips are simply glued to the connector or the terminal.
2. Optimize the speaker crossover solution
The switch also emits interference fields. Since this is usually not shielded and cannot be shielded, the radiation is that of Prof. Dr. Ing.Konstantin Meyl described Potential vortex to reduce. We have our own for that AIO interference suppression products developed. These have a field (bipolar active field), information to reduce the potential vortex (interference suppression) and to Reducing stress in humans (stress relief). By the Active field will the Debugging information radiated into the loudspeaker and can suppress the frequency crossover there.
If it is a large crossover and you want to suppress interference as much as possible, we recommend ours AIO round blank 70. If the frequency symbol is directly behind the connection terminals, you can use a AIO round blank 70 let it work from below or from the side on both the crossover and the loudspeaker terminals. You can use the AIO round blanks 30 or the 2D disposal chips waive. the AIO round blank 70 costs 118, - €.
The interference suppression of the switch with einr is cheaper AIO round blank 30which one sensibly lets work on the switch from the side or from below. One AIO round blank 30 costs 29, - € per piece (when purchasing 10 pieces).
If you expand the crossover, so can you 2D interference suppression chips insert. You can do this 6mm 2D interference suppression chips Glue to the ground potential in the coils as well as on the capacitors. The price per 6mm 2D interference suppression chip is € 2 (the chips are supplied on a 50-piece card).
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 possibility is the interference suppression by a AIO round blank 70 which is positioned under the loudspeaker at the front of the baffle. The aim is that all the chassis are covered by the field of the circular blank, which, like the light beam from a flashlight, emerges from the surface of the circular blank in a bundled upward direction. the AIO round blank 70 costs 118, - € each.
Biologically the largest samples are the interference fields with frequencies above 2.000 Hz. These should therefore be particularly suppressed. One possibility is the interference suppression by a AIO - pyramid on the speaker ahead at the edge of the baffle. The pyramid should stand in such a way that the “bottom” of the pyramid is “above” all the chassis. In this way, the AIO pyramid suppresses all chassis.
The AIO pyramids cost € 49 for the 30mm pyramid and € 89 for the 40mm pyramid each.
The perfect solution is the duplication AIO 70 round blank under the speaker and the AIO pyramid on the speaker. It is important to have the correct “polarity” of the interference suppression equipment. The best way to do this is to read the Operating instructions for the AIO pyramids on the subject of bipolar active field.
An inexpensive one Interference suppression the chassis represent ours 6mm 2D suppression chips These are attached in the center of the chassis on the membrane and, in the case of the tweeter, on the mounting plate below the membrane - so do not stick to the membrane in the case of the tweeter. Tweeters are usually 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 given on a card with 50 pieces).
