Common issues, Genelec solution
The 7040 is an ultra-compact subwoofer solution designed around Genelec proven Laminar Spiral Enclosure (LSE™) technology, enabling accurate sound reproduction and precise monitoring of low frequency content. The Genelec 7040 active subwoofer has been developed to complement Genelec 8010, 8020 and M030 active monitors. Such a monitoring system enables work at a professional quality level in typical small rooms, or not purpose-built monitoring environments, for music creation and sound design, as well as audio and video productions.
Low frequency accuracy
Low frequency accuracy To achieve a high sound pressure level an essential property of a subwoofer is its capacity to move high volumes of air without distortion. This presents challenges to woofer and reflex port designs. The solution is Genelec’s patented Laminar Spiral Enclosure (LSE™). It is a result of more than 10 years of continuous research of research work and manufacturing experience. The 7040 active subwoofer can produce 100 dB of sound pressure level (SPL) using a 6 ½ inch woofer and a powerful Genelec designed Class D amplifier. At the lowest frequencies this SPL is radiated from the bass reflex port, implying large volumes of air movement through it. The 7040 LSE enclosure is made from a spiral-shaped strip of steel, providing maximal mechanical stability for the large pressures generated inside the subwoofer. The spiral forms the bass reflex port as well, enabling linear air flow also at the highest SPL outputs. This flow-optimized construction provides extended low frequency capacity and low distortion resulting in precise bass articulation.
The design goal for the 7040 subwoofer was to develop a tool for professional, reliable, quality low frequency reproduction in a transportable package. The 7040 subwoofer weighs a mere 11.3 kg (25 lb) and features a universal mains input voltage for easy international connectivity. The two balanced XLR inputs and bass managed outputs, via an 85 Hz crossover, enable seamless extension with the main monitors. Calibration of the Genelec 7040 subwoofer to the listening environment is done using DIP switches located on the subwoofer connector panel. These controls address typical monitoring placement configurations. An optional carry bag allows professionals to work on the move, with portable recording devices and in improvised monitoring spaces with an accurate and flexible monitoring tool.
Small rooms have limited floor space. Genelec engineers have optimised the 7040 subwoofer enclosure with this in mind. With external dimensions of 410 x 350 x 205 mm (16 ¹/8 x 13 ¾ x 8 ¹/8 in) the Genelec 7040 subwoofer footprint is smaller than that of a small practice guitar amplifier and the subwoofer is narrow enough to fit in a 19 inch rack. All this while maintaining outstanding low frequency performance down to 30 Hz (–6 dB).
