The Authentic Voice
Originating directly from the experience of the outstanding Thesis line, the Voce components take the in-car listening experience to a new level of excellence. Innovative and advanced design, reference performance; the synthesis of a solid know-how employed in car audio reproduction.
The Voce project was born to make Thesis sound quality accessible to a wider, still demanding audience. The development of these components took advantage of the main innovations applied during the design of the Thesis line: drastic reduction of non-linear distortions, linearization of electric and acoustic load, control of membrane and cone back-wave reflections.
In order to achieve these goals, new materials had to be developed, new mouldings for baskets and cones had to be designed, new assembly and quality control procedures had to be prepared; a delicate work of analysis and refinement, that brought to achieving results which exceeded our own expectations, establishing a new reference for its own category.
The development of these new loudspeakers started from the drawing of the motor assemblies as well as their delicate interaction with the voice coil assembly, to obtain a linear magnetic flux, stability of the magnet working point and of the modulation of the coil inductance.
The result derives from an over-optimization of geometries and materials; the voice coil of all the components were made in extremely light Copper Clad Aluminium Wire, on Kapton former.
The woofer surrounds re-use the tested profile developed for the Thesis components: triple wave in butyl rubber for the surround and nomex fabric for the spider.
The new die-cast baskets of AV 5.0, AV 6.5 and AV 12 models take inspiration from the Thesis characteristics, and thanks to a delicate optimizing action they meet the two main requirements expected from these components: linearity in acoustic load on the back of the membrane and absence of mechanical resonances in the band-pass.
The same attention to mechanical design was devoted to the structure of the AV 1.1 tweeter; its front acoustic load is extremely linear, maximizing off-axis response; the rear damping chamber features an annular geometry, adjusting its characteristics with the needs of the membrane, also using an efficient and linear damping material, especially developed for this tweeter.
The woofer super-light membranes are made out of treated cotton fibre and pressed-paper, with a finish ensuring control of the break-up resonances in mid-high range, while the classic Tetolon® has been employed on the tweeter, the same mixed silk and cotton texture used for the magnificent Thesis TH1.5 tweeter.
Maximum attention has been put on thermal behaviour; for the new Voce components, a proprietary cooling system has been designed into the basket (located underneath the spider) and into the magnetic assembly. The air flow through the radial vents combined with the air flow running through the central decompression vent allows optimum working temperature of the voice coil assembly.
The Audison Voce line offers a complete and versatile range of components. The AV 1.1 tweeter features a very light Tetolon® membrane, 28 mm Copper Clad Aluminium Wire voice coil, Neodymium magnet and annular rear damping chamber. The AV 5.0, AV 6.5 woofers and the AV 12 subwoofer feature an aluminium basket with a great aerodynamic structure, a cotton-fibre paper pressed cone with Light Damping treatment, a triple wave surround in butyl rubber and extremely light Copper Clad Aluminium Wire co ils. The core of the AV 3.0 midrange is a powerful Neodymium magnetic group: efficiency and linearity make it an irreplaceable component to achieve a fine yet dynamic mid range, while its compact size allows versatile and high-performance installations.
The AV X5 and AV X6.5 coax speakers are the evolution of the woofers from the same line, thanks to the introduction of an excellent 1” Tetolon® dome tweeter, along with a refined dedicated crossover. The Orientable High Frequency Tuning technology also provides the ability to optimize dispersion in high range to achieve the best performance in the listening point.
The AV CX 2W MB crossover is especially thought for the AV K5 and AV K6 two-way complete systems, shaping their acoustic response to achieve a consistent, harmonious sound in any vehicle, also offering the acoustic controls necessary to achieve the best balance according to one’s own taste.
The AV CX 2W MH crossover is dedicated to the mid-high speakers of a three-way multi-amplified system, providing the ability to use multiple woofer sections, for maximum flexibility and absolute performance.
