Preview - Genelec 8260A 3-way DSP Active MonitorGenelec is very proud to be able to introduce to the market a major advance in audio driver technology integrated to a sophisticated enclosure design. With the new MDC™ Minimum Diffraction Coaxial Mid/High driver technology Genelec takes a step further in its task of refining audio quality in active studio monitors.
The 8260A is a master piece in electro-acoustic design as mechanical, acoustical, and signal processing designs are intimately linked together. It uses a die-cast aluminum enclosure, which provides new possibilities to perfect the quality of a monitoring loudspeaker. 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.
The 8260A loudspeaker system represents Genelec’s cutting-edge innovations in all technology domains: the corner stone of the enclosure design heritages the advantages of the 8000 series. In addition, the electronic domain (hardware and software) of the system benefits from the advanced 8200 Series design with advanced AutoCal™ auto-calibration system. The MDC™ coaxial MF/HF breakthrough solution makes the loudspeaker unique in the market.
MDC™ Minimum Diffraction Coaxial Technology
New Genelec breakthrough in Mid/High frequency performance
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 technical dilemma lies in the directivity control behavior of the loudspeaker’s midrange and high frequencies. With a compact enclosure, the constraint of having a too small DCW™ waveguide would particularly compromise the midrange radiation control. For this reason, the use of a coaxial driver was quickly outlined and the initial developments and prototype work on an advanced Genelec coaxial driver date from the late 90’s.
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.
This breakthrough in coaxial design provides improved imaging and overall sound quality on- and off-axis, extremely smooth frequency response leading to outstanding clarity and definition of the inner details of the music. Besides providing considerably more sound pressure than Genelec’s largest 2-way, the 8260A combines for the first time a coaxial driver (MDC™) within a modern waveguide (DCW™), ensuring drivers to couple coherently over their full operating bandwidth as well as being single MF/HF coincident point source.
New Genelec 1038CF 3-way Active Monitor
Genelec is pround to introduce the new 1038CF 3-way active monitoring system. Based on the highly acclaimed full range Genelec 1038B 3-way monitoring system and as a response to high customer demands for the same Mid/High performance in a compact package, the 1038CF main new features are a very flat enclosure depth (version F) of only 235 mm and dual 8” long throw bass drivers.
Our Genelec 1038B model, an impresive full range monitor with low end response down to 30Hz, has always been praised for its even dispersion characteristics in the Mid/High spectrum. Also, today’s audio production rooms are often small and most multichannel environments use a subwoofer combined with bass management to handle most of the LF content as well as the LFE channel signal. Given these parameters, the need to develop the 1038CF made full sense.
It features a limited bass response, with a -2.5 dB point at 57 Hz, as the focus is on Mid/High performance. The system should be used in combination with a subwoofer in either stereo or multichannel applications. The 1038CF very compact enclosure measures only 610 mm x 470 mm x 235 mm (HxWxD) making it highly suitable for on-wall, free standing as well as flush-mounted applications . The system has a built in amplifier unit delivering a total of 420 W into two 210 mm (8”) long throw bass drivers, 130 mm proprietary Genelec midrange driver and a 25 mm metal dome tweeter loaded into an advanced Genelec Directivity Controlled Waveguide (DCW™). The system is capable of delivering sound pressure levels of 124 dB maximum peak acoustic output per pair at 1 m measured with music material.
New Genelec 8020B 2-way Active MonitorThe successful Genelec 8020A 2-way active monitor system has been updated to become the 8020B. With this introduction, Genelec is clearly showing more emphasis on environmental care.
The basic change in the B model is the addition of a mains power switch now located on the enclosure’s rear panel. The rotary front panel control is used for sound level adjustement only. The audio signal can still be muted (the front LED stays on) in turning the front panel volume knob fully anti-clockwise, but actual mains power is only switched off using the rear panel on/off power switch which turns the front LED on/off. This also enables turning the power off without changing the set level, as in all of our other products. Along with this change, the second rear-mounted XLR connector has been removed.
The new Genelec 8020B (Height with Iso-Pod™ 242 mm, Width 151 mm and Depth 142 mm) has been designed for monitoring work in difficult listening environments, particularly those compromised by lack of space. The die-cast aluminum Minimum Diffraction Enclosure (MDE™) of the 8020B features relatively large internal volumes; softly curved edges and outstanding mechanical strength. The 8020B advanced Directivity Control Waveguide (DCW™) provides an amazingly smooth on and off axis response; while the long, curved reflex port ends in a wide flare for excellent bass articulation. As a result, the imaging accuracy and low frequency extension with such a compact enclosure are truly astounding.
The 8020B features a 105 mm (4 inch) bass driver along with a 19 mm (3/4 inch) tweeter loaded into a new advanced Genelec Directivity Controlled Waveguide (DCW™). The free field frequency response is 66 Hz to 20 kHz (± 2.5 dB). Maximum peak SPL output per pair with music material is 105 dB at 1 m. Bass and treble are each powered by 20 watt amplifiers.
