Genelec is now shipping the new 7040A, an ultra-compact subwoofer. Designed to be used with Genelec’s 8010, 8020 and M030 active monitors, the 7040A features Genelec’s Laminar Spiral Enclosure (LSE) technology. This enclosure design claims a high sound pressure level (an essential property for a subwoofer) and move high volumes of air without distortion.
Small rooms have limited floor space, and Genelec engineers have optimized the 7040 subwoofer enclosure with this in mind. With external dimensions of 16.125 x 13.75 x 8.125-inch (410 x 350 x 205 mm), the 7040A has a footprint that is smaller than that of a small practice guitar amplifier. It is also narrow enough to fit in a 19-inch rack and weighs 25 pounds (11.3 kg).
Calibration of the Genelec 7040A subwoofer to the listening environment is done using DIP switches located on the subwoofer connector panel. These controls address typical monitoring placement configurations.
The 7040A is spec’d to 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 by channeling large volumes of air movement through it. The 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 airflow also at the SPL outputs. Genelec says this flow-optimized construction provides extended low frequency capacity and low distortion resulting in precise bass articulation.
