Technology / Home Audio / Gas Plasma: Gas plasma emitters are a type of Horn Driver wherein a plasma or ionized gas field is developed and then propelled between two electrostatic grids. The onrushing gas is then compacted or dispersed in conformity to the frequency and level of the high voltage input signal. This type of driver, while very effective, is also extremely expensive, and so has not been commercially successful.
