The DCW technology shapes the emitted wavefront in a controlled way, allowing predictable tailoring of the directivity (dispersion) pattern. The Genelec DCW technology developed and refined over more than 30 years greatly improves the performance of direct radiating multi-way monitors. The end result is a simpler, more reliable, efficient, consistent and precise active loudspeaker system.ĭirectivity Control Waveguide (DCW™) for flat on- and off-axis response.Ī revolutionary approach was taken by Genelec in 1983 with the development of its Directivity Control Waveguide (DCW™) used at the time in an egg-shaped enclosure. Using the active approach enables frequency response adjustments and optimization of the full loudspeaker system, placed in various room environments, without expensive external equalizers. The flat frequency response of a high-quality active loudspeaker is a result of the combined effect of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.

The possibility to compensate for the frequency and phase response anomalies associated with a driver’s characteristics within the intended pass-band.

The ability to compensate for sensitivity variations between drivers.

This isolates each driver from the drive signals handled by the other drivers, reducing inter-modulation distortion and overdriving problems.

Each driver has its own signal processing and power amplifier.

There is an increased flexibility and precision to adjust and fine tune each output frequency response for the specific drivers used.

The frequency response becomes independent of any dynamic changes in the driver's electrical characteristics or the drive level.

The active crossover design offers multiple benefits: In a typical 2-way system the active crossover needs two power amplifiers - one for the woofer and one for the tweeter. This is in contrast to passive crossovers that operate at the high signal levels of the power amplifier's outputs, having to handle high currents and in some cases high voltages. Genelec analogue active crossover filters contain electronic components that are operated at low signal levels suitable for power amplifier inputs. Genelec digital active crossovers include additional signal processing, such as driver protection, delay, and equalization.

Active crossover operating at low signal levels.Īudio electronic crossovers allow to split the audio signal into separate frequency bands that can be separately routed to individual power amplifiers which then are connected to specific transducers optimized for a particular frequency band.Īctive crossovers come in both digital and analogue varieties.
