ZeroPads Ultra – set of 4

Ultra high-end adaptive & adjustable air-cushion vibration control system for audio-video devices, center- and bookshelf speakers.

The ZeroPads Ultra 4 adaptive piezoelectric & adjustable air-cushion vibration control system is at the top of the ultra-high-end category.

ZeroPads Ultra 4 is a revolutionary product incorporating state-of-the-art materials and technology. The ZeroPads Ultra 4 are designed to provide a stable structure allowing for adaptive and damping, and individual adjustment of the air-cushion damping force.

Each ZeroPads Ultra 4 adaptive isolation feet incorporates Audio Engineers’ unique design principles to deliver unbelievable results, providing a high degree of adaptive and air-cushion damping. The sound stage blossoms to open up a three-dimensional image of natural, spatial sound.





Zero resonances

ZeroPads Ultra 4 isolation feet are able to adaptive eliminate the higher-frequency and micro-resonances over a wide range, and the air-cushion system prevents the propagation of low and medium-frequency vibrations, taking the music listening experience to the highest level.

ZeroPads Ultra 4 adaptive isolation feet are designed for audiophile and high-end category audio devices, projectors, turntables, center-, bookshelf speakers, and speaker stands. ZeroPads Ultra 4 isolation feet have been crafted to provide an extraordinary acoustic performance with enhanced sound clarity.





Adaptive technology

The “soul” of the ZeroPads Ultra 4 isolation feet is are Active Crystal Balls, which implement adaptive vibration-control based on the piezoelectric principle. The special crystal balls placed in the ZeroPads Ultra 4 isolation feet is a quartz crystal with a synthetic hexagonal structure, which is almost perfectly spherical shape by precision fine-machining.

The advantage of synthetic quartz crystal over natural quartz is that its composition can be freely modified and does not contain impurities. As a result, its piezoelectric efficiency is better and its hardness is higher, which is partly due to the iron and titanium additives.

The weight of the device placed on the ZeroPads Ultra 4 adaptive vibration absorbers is constant, but the different vibrations exert a constantly varying pressure on the crystal balls placed in the vibration absorbers. The specially designed, inverted-cone ball sockets only contact the surface of the crystal balls with a thin rim, thus increasing the force of the pressure, while providing axial and radial damping.

The pressure and its change creates an electric charge of opposite polarity at the diagonal pressure points of the crystal balls, which excites an electric field. The strength of the electric field varies in proportion to the strength of the pressure. The electric field forces synthetic quartz crystal to change size in the opposite direction to the pressure change so that the Active Crystal Balls are able to eliminate higher frequency vibrations and micro-vibrations adaptively, as the reaction occurs in a fraction of a second.





Air-cushion technology

The Zero Pads Ultra 4 isolation feet also feature an optimally sized and precisely machined air-chamber. The piston of the air-chamber creates an air-cushion that is capable of extremely effective vibration damping as the device placed on the ZeroPads Ultra isolation feet almost floats.

The damping of the air-cushion can be adjusted in 4 stages using the included elastomer rings, from ultra-soft adjustment to hard, depending on the weight of the device placed on it or individual needs.

The inner damping rings of ZeroPads Ultra 4 are made of a special elastomer with high wear and heat resistance properties.

Magnetic connecting

The top and bottom of the ZeroPads Ultra 4 isolation feet are secured together by strong neodymium magnets.

The advantage of magnetic capture is that the resonances can only reach the active crystal balls, while the bottom and top of the ZeroPads Ultra 4 are tightly connected.





Ultra high-end quality

ZeroPads Ultra 4 is made of non-magnetic high-strength stainless steel (HSLA), which is also used in the automotive industry and has extremely high damping properties. The ZeroPads Ultra 4 isolation feet are made with precision and laser machining, using the lowest possible tolerances.





Lifetime Warranty

ZeroPads Ultra isolation feet are known the world over as best-in-class that allow the users to achieve outstanding performance and high quality.

However, there’s added peace of mind with the Audio Engineers Lifetime Warranty. Should your ZeroPads Ultra or absorbers ever malfunction from defects in workmanship or materials, we will replace that free of charge.





The ZeroPads Ultra 4 isolation feet provide full 3 dimensions axial and radial adaptive damping, enabling effective vibrations absorption in all directions. The combination of adjustable multi-stage vibration damping, air in the air-chamber, adaptive piezoelectric crystal balls, and a high-strength low-alloy (HSLA) stainless steel housing provides more effective vibration absorption than previous solutions.









NOTE: The metal parts of the ZeroPads Ultra 4 adaptive vibration absorbent must not come into contact with metal parts of the audio devices. Do not remove the insulating and absorbing discs from the bottom and top of the ZeroPads Ultra 4 adaptive vibration absorbers during use.

*ZeroPads Ultra products are warranted to be free of material and workmanship defects. Warranty coverage ends when the product becomes unusable for reasons other than defects in workmanship or material. Failures due to misuse, abuse, or normal wear and tear are not covered by this warranty. Audio Engineers shall not be responsible for any incidental or consequential damages. The lifetime warranty does not apply to the crystal and elastomer parts of the products.
