Monitor Audio's engineers have developed a secret weapon for the i-deck called Automatic Position Correction. An integrated microphone measures irregularities caused by non-ideal room positions and uses a sophisticated Digital Signal Processor (DSP) to automatically adjust the i-deck to deliver the ideal sound - this is achieved automatically each time you turn on the system at the mains.



Because positioning of a speaker is so important in determining the sound that you hear, we have integrated a Digital Signal Processor into the i-decks which automatically adjusts the output based on the environment in which the i-deck has been placed. This intuitive process takes place automatically each time you power up the i-deck at the mains so you always hear the best possible sound, no matter what space restrictions you are working with.



In order to liberate all of the music on your iPod/iPhone, i-deck takes the digital stream from your iPod/iPhone to its own high quality 28/56 bit dual precision Digital-Analoge converter (DAC). By keeping data in the digital domain until the last seconds of processing, our engineers have succeeded in preserving the essence of the original digital master.

Gold Dome C-CAM®

Gold Dome C-CAM®

The gold dome tweeter is formed from a ceramic-coated aluminium/magnesium alloy, gold anodised to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modelling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats.

The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.

C-CAM® Drivers

C-CAM® Drivers

Ceramic-Coated Aluminium/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminium/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.

Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAM tweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.

Airstream S300 Five-Star Review

"There's a lot to love about the Monitor Audio Airstream S300...."

"We play Lana Del Rey's West Coast and the S300's rich, full-bodied tone jumps to it; Lana's drowsy, breathy vocal is presented with expression and clarity."

"The midrange has a wonderfully clean character, and there's stacks of detail, giving a real insight into the track's subtler moments."

"The midrange stretches up into a smooth, controlled top end that can handle the hand claps on Kingdom's Bank Head without ever drifting into sharpness or hard territory."

"It's an alluring sound that grabs your attention right away and holds it, indulging you in a detailed and dynamic performance that will entertain time and again."

"...iOS users should most certainly RSVP."
