Ionomax – plasma speakers in a desktop audio system

Startup Cloudsound is preparing to launch unusual plasma columns Ionomax. They are superior in their characteristics to the usual dynamics, thanks to the physical process that underlies their work.

In most of the columns we use, compression dynamics are used, where the diffuser moves the air, or electrostatic, in which the membrane oscillates in a magnetic field. However, very few people know that there is also a third type of speakers – a plasma one.

Ionomax

A plasmodrive speaker, or plasma tweeter, is a speaker that generates sound by changing the air pressure with a corona discharge or an electric arc. Ionized air in an electric arc is thermally expanded and compressed, causing the air around the discharge to vibrate and create sound. The electric arc has negligible mass and inertia, which drastically reduces possible distortions. Due to this, plasma dynamics far exceed in quality of sound solid-state analogues with the membrane.

Ionomax speakers are supplied as a set of two parts: a preamplifier and the plasma speakers themselves. The preamplifier processes the incoming audio signal so that the bit elements of the column can create the desired arc.

The creation of plasma requires a high voltage – however, due to the thoughtful design of the Ionomax are completely safe. The preamplifier itself uses a low and safe voltage. When the signal enters the discharge module, a high voltage is generated in it, which creates an electric arc. This powerful current is enclosed in a shielded casing of the speakers and is not transmitted anywhere.

For additional protection Ionomax use aluminum alloy, which protects other devices from electromagnetic radiation from the speakers, and special glass absorbing ultraviolet radiation from the plasma.

The development of Ionomax began in January 2015, and on the market they will come out in November this year. The price of a set of a pair of speakers and a preamplifier is $ 499 .
