When space is at a premium, the 4020C is your compact, faithful friend. Designed for challenging commercial installations, the 4020C squeezes huge performance into a small package.
Precision and clarity
With beautiful aesthetics and 120 RAL colour finishes, the 4020C delivers Genelec’s trademark precision and clarity, with controlled directivity and the ability to adapt to challenging acoustic environments via simple rear panel room compensation switches. This ensures clean, intelligible, non-fatiguing audio whatever the playback level, plus bulletproof 24/7 reliability as standard.
Get more active
The active design of the 4000 series removes the need for bulky external power amplifiers, since the amplifiers, crossover filters and protection circuitry are contained within the speaker cabinet itself. This not only ensures that the electronics and drivers are mutually optimised, but also reduces the need for racks of external amplifiers and associated cabling. And thanks to our extensive range of mounting accessories, the 4000 series can be installed quickly and conveniently in almost any location.
Key Technologies
The speaker features a comprehensive range of advanced Genelec technologies designed to provide accurate, controlled, and reliable audio performance. Directivity Control Waveguide (DCW™) Technology ensures controlled and consistent sound dispersion, while Minimum Diffraction Enclosure (MDE™) Technology helps minimise unwanted cabinet-related acoustic effects. Reflex Port Design enhances low-frequency reproduction, and Room Response Compensation allows the speaker to be optimised according to the acoustic characteristics of the listening environment.
Optimised Amplifiers deliver clean and efficient power, while Active Crossovers provide precise frequency management. Protection Circuitry safeguards the speaker during demanding operation, and Intelligent Signal Sensing (ISS™) Technology enables efficient signal detection. Versatile Mountings provide flexible placement and installation options.
