About the No.7

The Lansche No.7 is a majestic three-way floorstanding loudspeaker system measuring 69 inches high by 17 inches wide by 24 inches deep. It features a unique Corona Plasma Tweeter that uses an 8mm electric arc to directly activate air, producing sound with no moving parts and achieving outstanding impulse, phase, and amplitude response. The speaker includes two 4-inch cone midrange drivers from Audio Technologies and four 8.7-inch long-throw woofers with coated fabric cones made of glass fiber and polyester. The enclosure is crafted from a composite of MDF and ceramic materials, reinforced internally and finished with fine wood veneer. It offers a frequency response from 25 Hz to 150 kHz, a sensitivity of 92 dB, and a nominal impedance of 6 ohms. The design emphasizes seamless integration of the massless tweeter with lightweight midrange drivers and powerful woofers to deliver coherent, natural, and highly detailed sound reproduction. The rear panel includes bi-wiring terminals, bass reflex ports, and controls for treble and bass adjustments. The No.7 is noted for its transparency, delicacy, and transient fidelity, making it a unique and captivating high-end speaker system.
