In the nineteen eighties the Atomic Loudspeaker engineers had developed the Vented Magnetic Gap Technology. This technology was intended to ensure proper heat displacement. This technology enabled the Atomic Loudspeakers to withstand larger amounts of thermal energy meanwhile protecting the magnetic structure from loss of magnetic force.

Electrical energy generates thermal energy (heat). When a voice coil is manufactured it is intended to tolerate a desired amount of heat. Exceeding the desired amount of heat ultimately results in the breaking down or burning up of a voice coil components.

Loudspeakers have powerful magnetic energy fields. The force of the magnetic field is measured in Tesla meters or Gauss. When a magnet or magnetic structure becomes exposed to relatively high temperatures, the amount of the magnetic force (Tesla meters) reduces permanently. After the loss of the intended magnetic force the original parameters also change and can cause detrimental effects.

A loudspeaker creates most of its heat inside the magnetic gap, in conventional loudspeakers the heat escapes slowly through the vent in the backplate (pole piece). The Atomic Loudspeakers have the ability to circulate cool fresh air in the exchange of the hot stale air a lot quicker! This circulation of fresh air-cools down the voice coil by hundreds of degrees, which in turn enhances the Atomic Loudspeaker's power handling capabilities and protects the magnetic structure from loss of magnetic force.

Atomic Loudspeakers have been used in sound-off competitions for a long time. The reason is simple; they are the loudest speakers on the face of the earth and are capable of handling more power. The V.M.G. technology has been one of the main reasons for the power handling capabilities.

In conventional loudspeakers venting is done through a hole in the backplate (pole piece). The pole piece of a loudspeaker also acts as a heat sink, absorbing the heat generated from the surrounding voice coil. The thicker the pole piece, the more heat it can absorb. This puts a great deal of emphasis on the diameter of the vent. Having a smaller diameter vent equals more material to absorb heat, but less area to vent the heat. This is also the same if the vent is too large, less material to absorb and more area available to cool.
