Vienna Acoustics Maestro Grand Center Channel Loudspeaker

At the heart of theater is the human voice. Our ears are most attuned to catch every subtle nuance of this expressive instrument.

Being the hardest working speaker in a surround system, the quality level of a center channel is of major importance to a system. Film sound springs to life from the Maestro Grand with a naturalness and intensity to match any of the Vienna Acoustics Grand main speakers. This extraordinary center speaker features an iris-shaped tweeter mounting block that allows this advanced 1” silk dome tweeter to work in perfect harmony with the dual 6” mid-bass drivers, utilizing Vienna Acoustics’ proprietary Spider Cone technology, in order to offer unrestrained dynamics and unparalleled detail in giving voice to even the most sophisticated of theater systems.

Handcrafted enclosures in beautiful wood finishes define the Vienna Acoustics aesthetic. The Grand Series features the following selections to complement any interior: Piano black, Maple, Cherry, and Rosewood.

Absolutely new is Maestro’s tweeter, an implementation of the technology found in the ultra high-end reference center channel, ORATORIO. The 1” silk-dome tweeter incorporates a triple stack neodymium magnet assembly mounted within an integral decoupling iris-shaped mounting block to reduce any extraneous resonance. Housing the tweeter in this assemble allows the tweeter to be positioned above the mid-bass drivers, assuring exceptional dispersion characteristics, as well as open and effortless high frequency response.

The two new 6” mid/bass Spidercone drivers used, based on the 7” reference driver found in BEETHOVEN Concert Grand, offer perfect bass dynamics combined with clear and natural midrange performance. The development of this driver was made possible by the experience gained in the development of X3P, which is a cone material that blends Vienna Acoustics exclusive TPX polymer and three polypropylene based synthetics to allow for maximum inner damping for midrange clarity, while the spidercone ribs provide maximum stability for bass impulses. Finally, these drivers benefit from a new inverted rubber surround design that constitutes a breakthrough in no loss damping of cone edge resonances. MAESTRO uses two of these unique drivers, combined with dual front ports, for ultra-fast, linear, and muscular bass extension to 38 Hz.
