Altavoces Vienna Acoustics Beethoven Concerto Grand

Caja acústica, precio pareja. Altavoz de suelo, 3 vias. Puerto reflex trasero. 4 Ohmios. Varios acabados. Muy buena calidad de sonido.

 Un aspecto exquisitamente clásico esconde el que sin duda es uno de los sistemas de altavoces más originales que se comercializan en el mundo como consecuencia del uso de una tecnología electroacústica extremadamente original. La Beethoven Concert Grand honra de este modo el espíritu apasionadamente melómano de Viena Acoustics, combinando tres exclusivos woofers con cono ranurado –“Spidercone”- XXP, un altavoz de medios con cono X3P y un tweeter de cúpula de seda con revestimiento especial bajo la eficaz dirección de un filtro con respuesta impulsional optimizada ejecutado con componentes de grado audiófilo (condensadores MKP de tolerancia muy estricta, bobinas con núcleo de aire, resistencias de película metálica libres de efectos inductivos). Completa este seductor panorama una construcción excepcionalmente depurada que permite aprovechar por completo las posibilidades de las configuración electroacústica descrita para proponer una presentación sonora de auténtica referencia.

Everything is new in the Vienna Acoustics Grand series, from the binding posts to cabinets to drivers. This represents a radical evolutionary revision of the Classic series that has served avid listeners well for nearly a decade. The new features outlined below, build on the many strengths of the past designs, while collectively realizing a greater sense of ease and resolution of musical detail throughout the line of new loudspeakers without any loss of the rich, dynamic sound for which Vienna Acoustic speakers have been known. Drive Units All bass and midrange drivers benefit from a new inverted rubber surround design that constitutes a breakthrough in no loss damping of cone edge resonances and from a reformulation of Vienna Acoustics’ proprietary XXP cone material. New 7” “Spider”cone bass drivers (used as Ultra Low Frequency, drivers on the Beethoven Concert Grand), feature a reworked motor assembly and revised placement of the XXP ribs, providing increased output, extension and control. A brand new 5” Spider cone mid-bass/bass driver takes advantage of the revisions developed for the 7” driver. With the introduction of this unit, dramatic improvements in bass output and extension were achieved, while simultaneously improving midrange clarity and detail. The new 6” midrange driver developed with a proprietary mixture of TPX, the base thermoplastic used in all XPP cones, and two polypropylene based synthetics to achieve maximum inner damping. This new polymer, dubbed X3P allows the driver to provide an extraordinarily wide bandwidth, while possessing a level of detail and control that is truly remarkable. The new tweeter employed was developed in conjunction with Scan Speak. The result of this collaboration is a tweeter with greater resolution of the subtlest of high frequency impulses while maintaining the renowned midrange warmth and clarity of the previous Beethoven / Mozart / Maestro. A completely new linear crossover layout, allows for more efficient transfer of signal to the drivers. New gold-and-silver alloy terminal for lowest transfer resistance and durability and proprietary cabling, consisting of large scale, hollow core solid copper conductors used throughout. Cabinetry The Beethoven Concert Grand boasts massive baffles that are 1.6” thick, 30% thicker than previous models, for maximum rigidity and resonance control. The revised grilles feature an integral V-shaped phase plug to control dispersion so that they can be left on for all but the most critical listening without a radical decrease in performance. Maple and Cherry finishes join a revised Rosewood, while continuing the state-of-the-art veneer-wrapping technology for the front and rear baffles first pioneered on the Classic series. A true Piano Black lacquer is now available, the quality of which will put most grand pianos to shame. Special decoupling and stability optimization through the use of the aluminum spike assembly and solid steel spikes on all floor-standing speakers.
