Accurate Professional Monitoring
The Genelec 8040B is engineered to provide a highly detailed and neutral listening experience, allowing engineers, producers and content creators to hear subtle details in recordings and make confident mixing decisions. Its maximum short-term SPL is 105 dB, providing substantial output for nearfield monitoring while maintaining controlled performance.
Genelec DCW™ Technology
The 8040B incorporates Genelec’s Directivity Control Waveguide (DCW™) technology, which helps control speaker directivity and provides a consistent response across the listening area. This contributes to accurate imaging and a wide, usable listening position for critical monitoring.
Active 2-Way Design with Dedicated Amplification
The Genelec 8040B uses an active crossover and separate optimized amplifiers for its bass and treble drivers. Its 90 W Class AB bass amplifier and 90 W Class AB treble amplifier provide a total of 180 W of built-in amplification, helping the speaker deliver high output and precise driver control without requiring an external power amplifier.
Minimum Diffraction Enclosure
The 8040B features Genelec’s robust die-cast aluminium Minimum Diffraction Enclosure (MDE™) design. The rounded cabinet geometry and rigid construction help minimize unwanted cabinet and edge diffraction while providing a durable enclosure for professional studio environments.
Flexible Room Response Controls
Different studio environments can influence the sound reaching the listening position. The Genelec 8040B includes adjustable room-response controls that allow users to compensate for acoustic characteristics and speaker placement. These controls include bass roll-off, bass tilt, desktop low-frequency and treble adjustments.
Intelligent Signal Sensing
The 8040B incorporates Intelligent Signal Sensing (ISS™) technology, which can automatically reduce power consumption when the monitor is not receiving an audio signal. Genelec specifies power consumption of ≤0.5 W in ISS active mode, helping reduce unnecessary energy use.
Ideal for Professional Audio Applications
The Genelec 8040B studio monitor is suitable for music production, recording, mixing, mastering, broadcast, post-production and other professional audio environments where accurate sound reproduction is essential.
With its powerful active design, controlled directivity, extended frequency response, room-response controls and compact professional enclosure, the Genelec 8040B remains a highly capable monitoring solution for critical listening and studio applications.
