The CORONA Ion tweeter – Lightening in a Bottle

This system reproduces the audio frequency exactly, without removing or adding any frequencies. With its upper limit frequency of 150kHz, it is also free of phase, timing, or linearity errors in the direct range of audibility and is miles ahead of other concepts with respect to impulse fidelity and precision. In this way, this tweeter system represents the ideal – not only in reproducing music in a living space with absolute perfection and authenticity, but also breathtakingly tangible while offering renewed reality to the gripping emotionality of the original. Instead of the indirect mass-laden membrane, air is excited directly by a visible arc of light and used as the sound transmission medium, resonance-free from 1.5kHz to 150kHz. It performs better than the ear and most amplifiers. This incomparable tweeter establishes the soul of our speaker system and is responsible for reproducing the fine overtones which, for example, make it possible to distinguish the characteristic sound of a Stradivarius from an Amati. No other transducer principle is capable of such precision and refinement.

The 4.1 loudspeaker system employs this most-advanced plasma tweeter, and it does so with critical precision. Like a musical instrument itself, the Lansche loudspeaker very naturally projects the sound of music with no apparent strain, recreating nuances within the music that you never knew existed. Lansche unfolds the tapestry of music revealing detail and musical significance, exposing the slightest of quivers from within the smallest of signals.

Matched seamlessly to the tweeter is their specially-developed doped-paper midrange cone. Thanks to its hard, almost motionless suspension, the powerful Neodinium magnet, and the extremely light (only 8 grams) coated Omniex membrane, it never loses its "connection" and offers the perfect complement with respect to its resonance and distortion behavior. As a wideband system, it also provides a perfectly phase-optimized crossover network using just two components of highest quality. Lansche has achieved uncompromised performance in all frequency ranges, presenting the most natural presentation of music throughout the critical midrange band.

The active bass system permits the reproduction of frequencies as low as 20Hz, and is tunable to the listening environment via level controls centered at four separate bass frequencies. This permits the speaker to be placed for maximum effectiveness in the room with respect to the entire spectrum of music – not just the low frequency balance. Powerful, fast, precise and clean – Lansche's low frequency performance is every bit world-class.

Lansche's technical achievements are unparalleled in other conventional loudspeaker designs, regardless of price – and their musical achievements must be heard to be believed.

Lansche is what you buy when "Best" is no longer good enough.
