Compact Active Subwoofer Design

The Genelec 5040B combines an integrated amplifier and bass driver in a compact enclosure, eliminating the need for a separate power amplifier. Its frequency response extends from 35 Hz to 85/120 Hz (-6 dB), depending on the operating configuration, providing the low-frequency foundation needed for music, film and multimedia playback.

Designed for Genelec 6010B Monitors

The 5040B was specifically designed to work with the Genelec 6010B compact active monitors and can support systems using up to five 6010B speakers. This makes it a practical solution for compact stereo and multi-channel audio systems that require additional low-frequency performance.

Remote Volume Control

A convenient remote volume control allows users to adjust the overall sound system level without having to access the subwoofer directly. This makes everyday operation easier in desktop, home audio and compact professional monitoring setups.

Flexible Acoustic Controls

The Genelec 5040B includes acoustic adjustment features that allow the subwoofer to be integrated into different listening environments. Its phase correction range of 0 to -270°, adjustable in 90° steps, helps optimize the relationship between the subwoofer and main monitors.

Intelligent Signal Sensing (ISS™)

The 5040B incorporates Genelec Intelligent Signal Sensing (ISS™) circuitry. When no audio input is detected, the system can switch the subwoofer into standby mode, helping reduce unnecessary power consumption.

Multiple Audio Connections

For flexible system integration, the Genelec 5040B provides 5.1 RCA analog inputs, a 3.5 mm stereo input and five RCA analog outputs. These connections make it suitable for compact stereo, multimedia and multi-channel audio configurations.

Ideal for Compact Audio Systems

The Genelec 5040B active subwoofer is an excellent choice when a compact audio system needs deeper and more powerful bass reproduction without adding a large subwoofer enclosure. Its compact dimensions, integrated 40 W amplifier, remote volume control, acoustic adjustment features and ISS™ technology make it a versatile solution for space-conscious audio systems.

Whether used with Genelec 6010B monitors or another compatible compact audio setup, the Genelec 5040B adds controlled low-frequency performance while maintaining a clean and unobtrusive installation.
