Avalon Flagship Series

, ,

How do you describe the indescribable? Surpassing all previous design conventions, ISIS represents the ultimate achievement in pinpoint accuracy from a full range high-energy transducer. Audio terms become almost meaningless in this award winning design that has already been recognized by the critics as “Revolutionary”, no other transducer is as complete in communicating the entire visceral and emotional impact of the musical event.

ISIS is the first full range loudspeaker in history to utilize proprietary neodymium magnetic technologies in all drive units, coupled to inert diaphragm materials of Nomex/Kevlar, Ceramic throughout with custom- smelted precious metal conductors. Multiple layering and material usage in there legendary cabinet construction eliminates the characteristic sonic signature of any “ single material” design.

ISIS £102400

is simply one of the most technologically advanced high-energy transducer ever created. Our focused research over a period of four years has produced a range of advancements in each aspect of loudspeaker performance. Proprietary conductors and magnetic technologies, as well as new techniques in cabinet construction, have been combined with the first implementation of full range neodymium driver motors, for the expressed purpose of empirical improvements in all aspects of energy transfer. In each facet of transducer refinement the Isis sets a new benchmark for lack of obscuring distortions of all types. The noise floor is lower, the transient response faster, the storage of stray energy less than ever before. Most importantly, the octave to octave energy balance is equivalent throughout the extended bandwidth envelope, developed without compression of any kind and yet critically damped, thus delivering a dynamic and spatial presentation that is absolutely faithful to the recording.

The result is a large dynamic system that behaves like a small monitor, revealing the most subtle details of space and time combined with the ability to create explosive sound pressure contrasts. By creating and combining our own proprietary technologies, we have produced a rare and exclusive transducer that will set the empirical and musical standard of reference for many years to come.

SAGA  £148000

Represents the synthesis of our multi-year research into low noise circuitry, developed during the TESSERACT design project, and the high resolution pin-point focus of Isis. Our in depth research over a period of four years has produced a range of advancements in each aspect of loudspeaker performance. Proprietary conductors and magnetic technologies, as well as new techniques in cabinet construction, have been combined with the implementation of an all neodymium full range driver array. A new family of all-pass phase networks confers empirical improvements in all aspects of energy transfer and transient speed. The noise floor is lower, the transient response faster, and the storage of stray energy is less than ever before. Most importantly, the octave to octave energy balance is equivalent throughout the extended bandwidth envelope, developed without compression and yet critically damped, thus delivering a dynamic and spatial presentation that is absolutely faithful to the recording. The result is a large dynamic system that behaves like a small monitor, revealing the most subtle details of space against black backgrounds within an envelope of explosive sound pressure contrasts. Modest impedance characteristics make macro dynamic distinctions possible with even low output, voltage source amplifiers.

The adherence to true high-end idealism, perfect phase behavior and accurate soundstaging, will stand the test of time when high priced mid-fi fads have faded into obscurity. Our goal is to always be true to our passion for music, while creating the most technologically advanced reference transducers in the world.

TESSERACT £poa

Represents the culmination of over 25 years of research into the subtleties of musical waveforms and the psychoacoustic perception of sounds in space. Our research into physical forms and how they react with ambient musical information has led us to two essential innovative concepts. First, it is possible to make a large full range system fully disappear sonically. Second, it is possible to create 3-dimensional images within a soundstage using conventional stereo recordings.

Our Stealth Technology, the redirecting and diffusion of ambient room energy, makes the disappearing act possible. The use of tensor field mathematics, assigning a value and direction to expanding harmonic waves, along with enormous amounts of number crunching, has given us the ability to make reliable predictions regarding which physical forms will best disappear in space. Making an array which is over 7 feet tall disappear is quite a feat of practical mathematical prediction and actual form fabrication.

Sonic Holography is accomplished through meticulousness in recovery and preservation of low level signal information which is encoded into any well made recording. Whenever a microphone is open it is collecting phase and spatial information which is rarely fully decoded by a playback system. This fragile information may be destroyed at many stages of the recording/playback process. Our goal is to preserve as much of the truth that inhabits each recording without putting our own fingerprints on the final presentation.

Most importantly, we never apply technique without considering the effect it will have on the emotional content of the presentation. For us technique is always in service to the music. There must be an aesthetic or emotional result for each intellectual or technical choice we make, one that speaks to our souls.
