Dali Oberon Vokal C Aktive-Center-Speaker


The OBERON VOKAL C was designed with TV audio in mind and despite its compact dimensions, the rendered audio performance is comparable to significantly larger speakers. The speaker cabinet comprises a compact and low profile - fitted with a 5.25” DALI wood fibre cone driver featuring SMC, and a DALI ultra-lightweight 29mm soft dome tweeter.

The compactness of the cabinet makes it easy to integrate into any room. To achieve a wide dispersion pattern in the listening area, the driver materials and geometry applied in the OBERON VOKAL C have been carefully selected. The same principles have been applied in the design of the crossover.

As result, you will experience a well-integrated sound, even when listening at a significant off-axis angle. This is important as you are rarely seated directly in front of your loudspeakers when listening to music. An added benefit is seriously reduced harmonic distortion and diffractions causing frequency distortion, as these will always be stronger in an on-axis response.


The OBERON VOKAL C uses two 5.25" bass/midrange drivers that feature DALI's proprietary fine paper pulp and reinforced wood fibre composite materials, creating a stiff, light-weight and well-behaving structure. In combination with a low-loss surround and spider suspension, this cone reproduces the micro details in the signal - unfiltered and with high accuracy. This is supported by the advanced copper-coated aluminium voice-coil wire and, in particular, our unique SMC (Soft Magnet Compound) magnet technology.

By introducing electrically non-conductive elements to the magnet structure, SMC significantly reduces the effect of a variety of distortion-producing mechanisms inherent to moving-coil driver architecture. For example, SMC minimises eddy current effects, increases flux linearity, reduces magnetic hysteresis and minimises the variation of voice-coil inductance. Taken together, these benefits make SMC equipped drivers particularly suited to active amplification.

The membrane terminates in a rubber surround that is chosen for its soft and very flexible properties. This gives the membrane free movement with a very low dampening effect and leaves the magnet motor to control the membrane movement.


The OBERON VOKAL C power amplification comprises two 50 Watt-peak, closed-loop Class-D power amplifiers chosen specifically for their sound quality and dynamic ability. One amplifier powers the high-frequency driver –the other powers the bass/mid drivers. The 100dB signal-to-noise ratio of the power amplifiers ensures that even the smallest detail in a quiet musical passage is reproduced with clarity and accuracy.

The electronic module mounted on the rear panel of the speaker incorporates a wireless receiver element and user setup interface, a DSP equalisation and crossover filter element, and a high-efficiency two-channel power amplifier with a closely integrated power supply.

Powering the amplifier is a custom-designed (65W(rms)), very low-noise switched-mode supply that is able dynamically to share resources between the two amplifier channels in response to demand. The OBERON VOKAL C is, as a result, unusually frugal in terms of power consumption, yet gives nothing away in terms of dynamic punch when the music demands it.


The high-frequency driver is a damped textile soft dome tweeter featuring an unusually light diaphragm and a larger than typical, 29 mm diaphragm and voice coil. The light diaphragm means that the upper-frequency response of the driver is unusually extended before its mass limited roll-off.

The large-diameter diaphragm and voice coil increases sensitivity and power handling, reduces distortion, and enables the driver to operate at lower frequencies than is the case with smaller tweeters, which helps provide more latitude in the crossover design. Further increasing power handling, and significantly reducing signal compression as the voice-coil temperature rises with increased volume, the driver is equipped with ferrofluid in its voice-coil gap.


The OBERON VOKAL C cabinets are constructed from CNC-machined high strength MDF panels and finished with a variety of wood-effect or matt white laminates. The cabinets are engineered for optimum rigidity to minimise panel resonance, with corner fillets. Corner fillets have become increasingly unusual in contemporary speaker cabinet construction but at DALI we believe they play an important role in ensuring rigidity.

Internal cabinet damping materials are selected and positioned strategically in order to maximise midrange energy attenuation without degrading bass transient response and bandwidth, as so often the case with reflex loaded speakers.
