Model No. 5.1 Boasts Legendary Corona Plasma Tweeter and
Musical Reproduction as Natural and Engaging as Live Performance
PARKER, CO, Nov. 22, 2011
— Aaudio Imports, a leading supplier of world class high-end audio products, introduces into the U.S. market the No. 5.1 Three-Way Loudspeaker by Lansche Audio of Germany, featuring Lansche’s legendary Corona Plasma Tweeter.
The No. 5.1 Loudspeaker is designed to produce music that sounds as direct and natural as when it was originally performed. With the speaker presenting no restrictions in dynamic range, frequency spectrum or reproducibility, listeners feel as if they had been transported into the middle of a live music experience.
The No. 5.1 Speaker replaces Lansche’s Model No. 5. It includes a new, improved version of the Corona Tweeter, a new midrange driver from Audio Technologies, a new crossover design, a slightly taller cabinet with a new aluminum front baffle, a new internal cabinet design, and a higher quality finish for the cabinet.
It reproduces sound using a 4-inch cone driver for midrange frequencies, two 8.7-inch long-throw drivers for bass, the Corona Plasma Tweeter for higher frequencies, and a passive bass reflex port. The low mass of the 4-inch driver seamlessly integrates the crucial midrange frequencies with the plasma tweeter, while the 8.7-inch woofers produce a solid bottom end, well beyond the usual home volume levels.
The Corona Plasma Tweeter, a hallmark of Lansche technology, comes closer than any other tweeter to the ideal of a point-shaped sound source with zero mass, since it employs an 8mm-long electric arc to directly activate the surrounding air as a sound transmission medium. The tweeter’s arc of resonance-free, voltage-modulated air helps it avoid the limitations of conventional tweeters to achieve outstanding impulse, phase and amplitude response, and an exact, three-dimensional sound. As a result, the No. 5.1 delivers faithful, coherent musical reproduction with incredible precision, speed and economy.
The No. 5.1 Speaker also boasts a meticulously crafted, 41-inch high cabinet with sandwiched composite walls that are the basis for the loudspeaker’s outstanding audio performance. Thanks to the cabinet’s extensive internal cross-bracing matrix and the application of custom-made damping materials, cabinet wall resonances have been reduced to vanishingly low levels. There is no opportunity for the cabinet to develop any resonant response of its own. Inputs include one for the midrange frequencies and tweeter, one for the bass, and a bi-wiring terminal on the back that can be adjusted to help the tweeter better match a room’s acoustic characteristics.
Lansche’s No. 5.1 Loudspeaker is available now from Aaudio Imports at suggested prices of $40,000/pair in a Satin Veneer ”¨finish, and $45,000/pair in a High Gloss Veneer”¨ or a Piano Black Lacquer finish.

About Lansche Audio
Based in Konstanz, Germany, on the shores of Lake Constance, Lansche Audio was founded by Rudiger Lansche in 1998, shortly after beginning manufacture of the Corona Plasma Tweeter. The tweeter is exclusive to Lansche and legendary for its extraordinarily accurate three-dimensional sound. Through considerable research, Lansche developed midrange and bass drivers fast enough to keep up with the Corona’s lightning-quick response. Speaker models No. 3, Cubus, No. 4.1, No. 5, No. 8.1, No. 7 and No. 5.1 followed, providing Lansche with a powerful line of highly expressive high-performance speakers. Lansche also implemented steady design improvements in the Corona Plasma Tweeter making it, in Lansche’s opinion, the best tweeter in the world.
