LEVAR RESONANCE
MAGNETIC ABSORBERS
All it takes is a revolution
The LEVAR magnet device feet work according to the principle of magnetic attraction. A piston moves in a magnetic ring. Compared to conventional magnetic bases, which are based on repulsion, the LEVAR magnetic bases automatically center the piston and the designer has a certain freedom to control the linearity of the magnetic spring action.
Scope of Application
Thanks to the patented arrangement of special and extremely strong neodymium magnets, we have succeeded in seamlessly covering the entire weight range from 20 to 200 kg per set of 4 for a wide variety of device requirements
Technical Summary
In contrast to the levitation designs already on the market, the new Levar Resonance magnetic dampers are based on the principle of gravitation, i.e. magnetic attraction. Here, a piston moves in a magnetic ring.
Compared to conventional magnetic bases, which are based on repulsion, the LEVAR magnetic bases automatically center the piston, and the designer has a certain freedom to control the linearity of the magnetic spring action.
This makes these absorbers highly resilient and stable, and allows us to manufacture devices with extremely compact dimensions.
A special feature of this magnetic damper is the complete decoupling of components from even the smallest and finest resonances and vibrations emanating from the supporting floor into the device, and vice versa. In this way, undesirable microphonic effects are avoided.
Optimal Application
For optimal use, the dampers must be placed directly under the bottom of the device so that a level connection is guaranteed.

Threaded pins for LR magnetic absorbers
All LR magnetic feet are equipped with an approximately
17 mm deep M8 internal thread.
To screw the magnetic feet to speakers and other devices, M8 set screws and M8/M6 adapters / reducers are typically available in two lengths each.
M8 Grub / Set Screws
30 mm (10 - 20 mm useful length *)
40 mm (20 - 30 mm useful length *)
* If the length is not sufficient, these threaded pins can only be partially screwed into the feet.
However, it is recommended to turn them in at least 5 mm.
M6 > M8 Adapters / Reducers
Version A / M6 useful length - 6 mm
Version B / M6 useful length - 12 mm
* These threaded pins must be screwed in completely

The Challenge ...
Sound waves are the basis of everything we hear acoustically. Sound waves are triggered by vibrations and oscillations, which reach our hearing via the ambient air that has been set in motion. The human ear “usually” perceives vibrations from musical instruments or singing voices as pleasant. The best way to experience music in a real and authentic way is of course a live performance. For this you are forced to attend a concert.
However, in order to be able to reproduce music as realistically as possible in the home environment using a hi-fi system, a sometimes quite high level of technical effort is required. Since our human hearing is very sensitive and can precisely perceive even the smallest nuances, hi-fi enthusiasts often spend a lot of money on suitable equipment.
But where there is light, there is also shadow. The vibrations and oscillations generated when listening to music inevitably cause disruptive resonances and feedback effects in the room. The sound radiation from loudspeakers causes everything else in the listening room to vibrate, which is physically inevitable. The floor of the room, on which the hi-fi system naturally stands, reacts very sensitively, as do the walls and all objects in the room. The feedback effects that affect the music system in this way undeniably have a negative effect on the quality and purity of the sound. No matter how heavy the base, such as granite slabs, will help. Regardless of their weight, these swing happily. In addition, footsteps or the finest vibrations from surrounding roads or even railway lines are unpleasant.
A record player reacts most sensitively to resonances and vibrations. But CD players and tube amplifiers don't like this either (microphonic effect).
So what can be done to eliminate disruptive resonances as efficiently as possible?
Of course, this is where damping elements come into play. There are heaps of these on the market. However, despite their advantages, these all have one decisive disadvantage in common: Due to their design, they also represent a firm connection to the floor space. Because even the best and softest base hardens due to the applied load (e.g. loudspeakers) according to the weight and ultimately forms but again a firm contact to the ground. The material-specific signs of fatigue of the soft materials used should not be concealed.
Optimal resonance damping would inevitably be an air cushion without any intermediate material for the audio component to rest on. This is where our innovative and patented LEVAR RESONANCE MAGNETIC ABSORBER with magnetic functionality come into play. These damping elements were specially developed to produce the best possible and therefore optimal damping without the use of soft materials (rubber, gel, etc.). There is a magnetic field here, only with air in the damping area, which is extremely effective in eliminating vibrations.
What they say ...
"...The idea is impressive, even if it is not completely new : Instead of elastic, dampening materials, magnetism ensure a practically complete decoupling from the background and thus prevents any influence, for example from impact noise or bass lines coming from the loudspeaker.
The device literally "hangs" in the air, i.e. on an air cushion.
Test with tube equipment
In the test, we used tube components that were more sensitive to microphonics, such as the Modulus M3A preamp from Audible Illusions, an older stereo tube power amp Q-3535 from Sansui, and an Appassionato LUA tube CD player Mk III.
Each isolated component exhibited a very clearly audible sonic performance.
The positive effect included audibly more "breath", increased clarity and better harmonic structure, as well as reduced distortion across the entire auditory spectrum.
Our transistor amplifiers and, of course, our turntables in particular, also benefited from the “exemption” here.
These feet are highly recommended, definitely try them out !"

... more of what they say ...
TOTALLY DECOUPLED ... TOTALLY TRANSFORMED
Everything used to be more difficult ... back when there was no neodymium ... and for a long time magnets could not achieve the force effects as they do today, especially with these totally novel absorbers from Levar.
Sonically, the transition from the hard spikes to the Levar decouplers resulted in most striking differences in our system, particularly in the bass which was literally "transformed", revealing a much tighter and better differentiated pace.
Atop this newly found "lower-spectrum foundation" appeared a very noticeably "liberated upper-spectrum , replete with enhanced spatiality and emotional vibrancy.
