Genelec is now shipping its new 8260A Three-Way DSP System.
With the new MDC Minimum Diffraction Coaxial Mid/High driver technology, the 8260A aims to be a "master piece in electro-acoustic design".
As we know Coaxial drivers have existed for many years and are common in two way systems but not so much in three way systems reproducing only mid and high frequencies. Typical to all current coaxial design is somewhat ragged frequency response due to inherent diffraction problems. Though, crossover issues due to non-coincident location of sources are solved with a coaxial configuration. Here lay the seeds of Genelec's Minimum Diffraction Coaxial (MDC ) solution: while it benefits from typical coaxial design advantages, it now overcomes several shortages as well.
The main structure of the MDC tweeter-midrange coaxial design consists of an integrated cone-surround-tweeter construction, where the cone suspension consists of a smooth and curved surface. The visible surface of the coaxial driver is formed only by the curved foam surface with the coaxial tweeter assembly in its center. The inner section joins the cone to the tweeter structure without any acoustical discontinuity, and the outer one does the same between the cone and the driver chassis. As there is no acoustically observable joint between the tweeter and the cone, there is no diffraction either. The cone profile is designed to form an integrated directivity control waveguide for the tweeter radiation. The cone outer edge is terminated by a DCW waveguide in order to control the dispersion of midrange radiation as well.
The 8260A uses a die-cast aluminum enclosure. For given external dimensions the internal effective volume can be increased, improving low frequency efficiency and providing extended LF cut-off which is at 26 Hz (-3 dB) in the 8260A. Also, enclosure vibrations can be eliminated by integrating stiffening ribs. The DSP processor in the 8260A contains all basic loudspeaker signal processing functions, such as the crossover filters, driver equalization, driver position alignment, as well as all the room alignment related filters, such as the room response equalizers and time-of-flight correction.
The Genelec Loudspeaker Manager (GLM ) software handles 8260A as any other 8200 series DSP loudspeakers in a system, allowing mix of different models within the same setup. Genelec AutoCal , part of GLM , is the unique automated room calibration and sound system alignment method providing consistent and accurate frequency response for a multichannel audio system in widely varying room environments.
Genelec's 8260A Three-Way DSP System is now available.
