Genelec 4010A 3" 2-Way 50W Powered Installation Speaker (Single, Raw Finish)

In a typical 2-way system the active crossover needs two power amplifiers—one for the woofer and one for the tweeter.

• The frequency response becomes independent of any dynamic changes in the driver's electrical characteristics or the drive level.
• There is an increased flexibility and precision to adjust and fine tune each output frequency response for the specific drivers used.
• Each driver has its own signal processing and power amplifier. This isolates each driver from the drive signals handled by the other drivers, reducing intermodulation distortion and overdriving problems.
• The ability to compensate for sensitivity variations between drivers.
• The possibility to compensate for the frequency and phase response anomalies associated with a driver’s characteristics within the intended pass-band.
• 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.

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 end result is a simpler, more reliable, efficient, consistent, and precise active loudspeaker system.

• Flat on- and off-axis response for wider usable listening area
• Increased direct-to-reflected sound ratio for reduced control room coloration
• Improved stereo and soundstage imaging
• Increased drive unit sensitivity up to 6 dB
• Increased system maximum sound pressure level capacity
• Decreased drive unit distortion
• Reduced cabinet edge diffraction
• Reduced complete system distortion

• A common problem with standard free-standing loudspeakers is that the front baffle discontinuities cause diffractions and the loudspeaker sharp corners act as secondary sources through reflections.
• In order to improve the flatness of the frequency response and the power response of free standing loudspeaker systems, Genelec have designed a highly innovative enclosure optimized to match the properties of the monitor drivers, featuring rounded edges, and gently curved front and sides. In addition to achieving an unsurpassed flatness of the frequency response, the enclosure having minimum diffractions yields superb soundstage imaging qualities.
• To achieve such a smooth and elegantly curved cabinet surface and to reduce the outer dimensions of the enclosure, maximizing at the same time the internal volume for improved low-frequency efficiency, Genelec designed a cabinet made of die-cast aluminum. Aluminum is lightweight, stiff and very easy to damp to yield a “dead” structure. The cabinet walls can be made fairly thin, providing at the same time good EMC shielding and an excellent heat sink for the power amplifiers. Die-casting is made in two parts, front and rear, and they are easy to separate for potential servicing needs.
• The DCW waveguide has been integrated in the MDE aluminum enclosure to provide improved control of the loudspeaker’s directivity. Basically, the low-frequency limit for constant directivity is determined by the size of the waveguide, so the larger the surface the better the control. With a very controlled off-axis radiation, the listening window becomes consistent, which is of utmost importance with multi-channel audio monitoring. Controlled directivity also reduces possible first order reflections on surfaces near the loudspeaker, helping to provide consistent audio reproduction in different acoustical environments. In fact, the entire front baffle is gently curved and the acoustically transparent grilles are part of the outer cabinet aesthetics, blending perfectly with the various other curved surfaces.

• The power amplifiers are directly connected to the speaker drivers, maximizing the control exerted by the power amplifier’s damping on the driver’s voice coil, reducing the consequences of dynamic changes in the driver electrical characteristics. This may improve the transient response of the system.
• There is a reduction in the power amplifier output requirement. With no energy lost in the passive crossover filter components, the amplifier power output requirements are reduced considerably (by up to 1/2 in some cases) without any reduction in the acoustic power output of the loudspeaker system. This can reduce costs and increase audio quality and system reliability.
• There's no loss between amplifier and driver units results in maximum acoustic efficiency.
• Active technology achieves superior sound output vs. size vs. low-frequency cut-off performance.
• All loudspeakers are delivered as a factory aligned system (amplifiers, crossover electronics, and enclosure-driver systems).

The protection circuitry prevents driver failures by detecting signal levels, and in case of sudden peaks or constantly too high levels, taking the signal level down automatically. Of course this feature does not affect the sound quality in any way when working within the specifications of the loudspeaker, but only prevents inadequate input signals from breaking the loudspeaker.

• Reduces the output level when required, (e.g., when driver voice coil temperature reaches the safe limit), which highly improves the system reliability.
• Appropriate protection circuitry design in every loudspeaker and subwoofer enables to maximize system output sound level.

• Genelec’s choice for vented, or reflex, enclosures date back to the S30 model, the first Genelec product from 1978. Port performance has been improved and refined over the years with the aim to increase the woofer’s low-frequency extension and sound-pressure level capability to provide outstanding bass articulation and definition.
• Both driver and vent contribute to the total radiation of a reflex enclosure. Most radiation comes from the driver, but at the vent-enclosure resonant frequency the driver displacement amplitude is small and most of the radiation comes out of the vent.
• To minimize the air speed in the tube, the cross sectional area of the vent should be large. This in turn means that the vent tube has to be long, which presents quite a design challenge.
• The long, curved tube maximizes airflow, so deep bass can be reproduced without compression. The reflex tube terminates with a wide flare located on the rear of the enclosure for obvious reasons, minimizing port noises and providing excellent bass articulation.
• The curvature of the tube has also been carefully designed to minimize any audible noise, compression, or distortion. The inner end of the tube has proper resistive termination to minimize once again audible chuffing noise and air turbulence.
• Proper reflex port design allows also to significantly reduce the woofer’s displacement, improving the linear low-frequency output capacity.

• The Treble Tilt control (switch 3) attenuates the treble response of the loudspeaker at frequencies above 5 kHz by 2 dB, which can be used for smoothening down an excessively bright sounding system.
• The Bass Tilt control offers three attenuation levels for the bass response of the loudspeaker below 2 kHz, usually necessary when the loudspeakers are placed near a wall or other room boundaries. The attenuation levels are -2 dB (switch 4 “ON”), -4 dB (switch 5 “ON”) and -6 dB (both switches “ON”).

• Base: 3/8" UNC threaded hole compatible with a standard microphone stand
• Rear: Three pairs of threaded holes compatible with Omnimount, VESA, and Sanus brackets
• Wall Bracket: Allows suspending the loudspeaker on a wall in two different angles
