Infinite Wisdom Grande Loudspeaker
The Infinite Wisdom Grande is the pinnacle of our achievements, representing a milestone in the evolution of loudspeaker design. Unlike any other system ever produced, it was conceived for environments too large for other systems, including multi-level rooms in the largest homes and palaces, great halls and ballrooms. Employing stacked three section planar-magnetic arrays over 13 feet tall, low frequency assemblies over 8 feet tall and a total system weight of almost two tons, this is a monumental system.

The Infinite Wisdom Grande is not only capable of high sound pressure levels in excess of 120 dB, but it achieves this in an effortless manner with unequaled sonic refinement. The unprecedented number of transducers employed yields an immense sound generating surface area capable of very high sound pressure levels, while also allowing for a significant reduction in all types of transient distortion. At levels below 110 dB, each transducer is operating at a fraction of their potential and, consequently, within their lowest distortion range. This contributes to the extraordinary detail, clarity, absence of dynamic compression, natural timbre reproduction and effortless quality of the system.

The stacked Infinite Series three section planar-magnetic arrays are mated to mammoth low frequency assemblies incorporating twelve 12-inch, underhung, 3-inch voice coil low frequency regenerators per channel, for a total of twenty-four drivers per pair.

The Infinite Wisdom Grande is a triumph of our transducer technology and design principles. It offers a unique solution for those discerning music lovers with large-scale environments unsuitable for lesser systems. Unlike any other system in concept or execution, the Infinite Wisdom Grande defies categorization and is in a class by itself.
