Boxe profesionale active URGENT!!! PRET UNIC!!! (pretul este pe bucata)

LEM is proud to announce a breakthrough in the field of professional loudspeaker systems. For the first time the digital processing technology, up to now only used for high-end products, is available in a loudspeaker system designed for musicians, DJs, clubs owner's and audio technicians, with a price within everybody's reach.
The new D400 combines to the most advanced solution as far as the cabinet construction, the speakers and the power amplifiers are concerned, an extremely powerful digital processor able to provide performances up to now impossible to obtain in this range of products. D400 is housed in a cabinet made of plastic material (high-density polypropylene), which provides a very light weight and a stylish design. The speakers used, from the 1" compression driver with titanium diaphragm to the 12" woofer with neodymium magnet, guarantee high performances and an exceptional sound quality. The built-in power amplifiers have been designed without compromises, in order to offer a big dynamics and an output power with no tricks. Finally, the digital processor with 24bit, low-noise conversion system and 40bit processing power, is able to perform with very high precision all the processing features needed for the best acoustical performances: from the high-precision EQ and crossover filters to the delay lines for the speaker alignment and the multi-function digital protection system for the maximum speakers durability and reliability.
key features
