Genelec Ships 7040A Ultra-Compact Subwoofer

Genelec is now shipping its new 7040A, an ultra-compact subwoofer for small spaces. Designed to complement Genelec’s 8010, 8020 and M030 active monitors, the 7040A delivers accurate sound reproduction and precise monitoring of low-frequency content.

Genelec said the subwoofer’s performance characteristics, combined with a compact form factor, make the 7040A ideal for use in music creation and sound design applications, as well as audio and video production work in small rooms and improvised monitoring environments.

The 7040A is the latest addition to Genelec’s line of active monitors, and like the rest of the product line, all electronics, amplifier circuitry, drivers and enclosure have been designed and assembled, tested and calibrated individually in the Genelec factory in Finland.

The 7040A features Genelec’s Laminar Spiral Enclosure (LSE) technology. This unique enclosure design is the result of more than ten years of research work and manufacturing experience and allows the 7040 to achieve a high sound pressure level (an essential property for a subwoofer) and move high volumes of air without distortion.

“A trend in recent years is toward smaller-scale facilities and work that is often more focused in scope,” said Will Eggleston, Genelec’s marketing manager in the United States. “But these spaces and projects still demand a high level of performance in regards to equipment, and Genelec has addressed these needs with the 8010, 8020 and M030 active monitors.

“The 7040 – a professional, reliable low-frequency reproduction subwoofer – is the perfect complement to these models and together provide a comprehensive, small-footprint solution to serve this growing market sector.”

Genelec engineers have optimized the 7040 subwoofer enclosure for small rooms with limited floor space. With external dimensions of 16.125 x 13.75 x 8.125-inch, 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.

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 produces 100 dB of sound pressure level (SPL) using a 6.5-inch woofer and a Genelec-designed Class D amplifier. At the lowest frequencies this SPL is radiated from the bass reflex port by channelling 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 highest SPL outputs. This flow-optimized construction provides extended low frequency capacity and low distortion resulting in precise bass articulation.
