I have a pair of 2.5 year old piano black Lansche No.3's for sale. This pair has the more recent plasma tweeters. The speakers are in excellent condition.THE LOUDSPEAKER The No.3 Loudspeaker is a perfect introduction to the fascinating sound world offered by the CORONA plasma tweeter. The construction principle is a two-way loudspeaker with a bass reflex system. The goal of this design is to create a benchmark reference loudspeaker with near compact dimensions and an elegant appearance easy to integrate into any living or listening space. DESIGN The biggest challenge with a two-way design such as this is to develop a driver for the midrange and bass frequencies that is perfectly matched to the speed and resolution of a plasma tweeter. The driver itself consists of a special cellulose membrane (paper membrane) with an additional coating.
The driver design combines a very fast midrange response with a surprisingly low bottom end. The No.3 model is powerful enough to provide a full sound even in large spaces. Special attention has been paid to the cabinet design. Extensive bracing and sophisticated interior damping (sandwiched layers) ensure that cabinet vibration is kept to an absolute minimum. All the components involved in sound reproduction are housed in their own isolated enclosures. The frequency crossover is located in the base plate, sealed inside a layer of quartz sand. This ensures that absolutely no vibrations are transmitted, and none of the components are susceptible to microphony. The base plate is a one-centimeter-thick aluminum slab which also holds the floor spikes. The loudspeaker cabinet is thus completely decoupled from the floor. The angled inclination of the narrow baffle is an effective solution for time-correcting the impulse responses from the two transducer systems. The loudspeaker's phase position is perfect at a seated listening height. Product Specifications: Description:
