The Music

Revolutionary New Driver

Vienna Acoustics "THE MUSIC" introduces a truly revolutionary new flat, concentric 18 cm driver that closely approximates the Platonic ideal for which speaker designers have been striving. It places 7 octaves of music in a single, phase coherent time plane. With a wave launch that mimics a "pebble dropped in a still pond", this remarkable driver reproduces spatial coherence unfamiliar to anyone, save perhaps the original recording engineer.

The physics of this patented driver are an outgrowth of Vienna´s longstanding use of reinforced cones designed to maximize strength at nodal multiples, while keeping mass to a functional minimum.

Flat cones actually do not provide stiffness, but we turned a disadvantage into an advantage by our patented one-sided-cone-light-weight-framing. Not only this delivers the best weight-stiffness ratio of any construction (the construction coming close in stiffness is sandwich, but it is too heavy as it needs a second layer and a dense honeycomb mesh), it also allows specific and calculated sound and impulse-response tuning by varying the quantity of ribs, their shape, their thickness, radial or concentric orientation, and specified placements on critical spots.

The basis for the cone material is TPX, in a proprietary mix with other materials for the optimum result of stiffness/inner-damping ratio in combination with light-weight-framing on the cone's rear side. The maximum final stiffness is defined by adding glass fibres to the compound, aligned in the optimum arrangement by according injection moulding tool execution.   All cones are developed and produced by Vienna Acoustics in Austria, afterwards manufactured to a complete driver by Eton Germany.

By using finite element analysis, Vienna Acoustics ´chief designer Peter Gansterer was  able to create a radial-veined structure (like architecture scientists we place a rib where necessary), cast into the flat cone that produces an enormously stiff, flat surface(thereby eliminating time and frequency specific phase shift across the driver), with a new state of the art silk dome tweeter, using a vented neodymium magnet structure placed in its centre.

Years of development made the flat cone possible, for Peter Gansterer the prerequisite of a realization of the optimum reproduction unit, a coax. Having 2 drivers at the same centre (point source), results in otherwise inaccessible homogenous sound, but current technology of cone shaped midrange diaphragms disqualifies itself by unacceptable colourations of the tweeter by the cone induced horn loading. In our technology it enjoys a flat surrounding as usual in high-end applications. Similarly, the midrange itself is incomparable in its lack of coloration: Cone-shaped drivers reproduce upper midrange mainly by the inner part, which again suffers from the horn loadings distortion.

At the same time our flat cone is ultra-stiff because of the ribs and the glass fibres, but exhibiting smooth musical sound due to the soft inner damping of the TPX material. The resulting piston like behaviour extends the frequency span, resulting in a range from 100 Hz to 20.000 Hz from the coax alone, defining it as the heart of the speaker, thereby being also the heart of music reproduction. We are that enthusiastic about this music centre that we gave it its own cabinet.

Bass Drivers

While the top-unit handles mid and upper bass in its own enclosure, below this primary driver we built a separate large enclosure, featuring 3 proprietary bass drivers, each with our on proprietary 25 cm ultra rigid NAWI cones die cast by Spider cone-framing (finally assembled also by Eton Germany), handling the frequencies from 18 Hz to 100 Hz. The 3 units are working in parallel, while the upper bass operates in its own chamber. Finally, a remarkable Super tweeter manufactured by the Japanese high-end specialist Murata, t ops the lower enclosure, extending response from 20.000 Hz upwards to 100.000 Hz.

Super Tweeter

During development we revealed that piezo technology, which is used in the super tweeter, has superior advantages above 20.000 Hz (optimum dispersion, acting like balloon inflating).

The total decoupling from the bass chambers allows the coax music centre, in its dedicated housing, to reach the absolute optimum in clarity and naturalness in sound.

Cabinet & Finishes

The cabinetry is clearly evolved to make the most of this technology; the separate top unit enclosure is decoupled from the bass enclosure by a high-tech, drawn aluminium swivel joint, which allows optimum room  tuning by enable not only adjustment for rake, but also for toe-in.

This allows you to create a sweet zone rather than a narrow sweet spot. By adjusting the dedicated coax point source cabinet and directing it like swivelling a flashlight you are able to easily create the sweet zone wherever wanted. Furthermore this allows for optimizing the sound to any room condition as many rooms will strongly benefit from the reduction of the disturbing early reflections which cannot properly be separated from the direct signal by the human ear.

As always, the speaker’s veneer and finish quality is to the highest of standards. "THE MUSIC" is available in true Piano Black version and Sapelle veneer finish.
