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.

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. All cones are produced by Vienna Acoustics in Austria, 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-vaned 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 special silk dome tweeter, using a neodymium magnet structure placed in its center.
