About Lansche Audio
Lansche Audio is a manufacturer of passive high-end loudspeaker systems based in Konstanz on Lake Constance. The centrepiece of all models is the CORONA plasma tweeter, manufactured exclusively in-house, which generates sound without a solid diaphragm directly via an ionized air field in the frequency range from 1,500 Hz to 150 kHz. The product portfolio comprises the P-Series (models No.3.2 MKII, No.5.2 MKII, No.7.2 MKII, No.8.3 and No.9.2) as 3-way or 3½-way bass-reflex systems with weights of 53 to 350 kg per loudspeaker. The cabinets are made from a composite of MDF and absorber dense foam with a reinforcing matrix construction; materials used also include aluminium (drivers, base plates), coated papyrus, paper and fibreglass for the diaphragms as well as multi-layer piano lacquer for the surfaces. Customers are sound enthusiasts and professional recording studios. The company places emphasis on sustainable production, a long-term model policy and comprehensive service.
