EASY TO POSITION
The driver materials, crossover design and geometry applied in the OBERON C series has been selected to achieve a wide dispersion pattern. This ensures a well-integrated sound, even when listening at a significant off-axis angle. An added benefit is seriously reduced harmonic distortion and diffractions causing frequency distortion. This is why all DALI speakers are not designed to be toed-in.
LOW LATENCY
The SOUND HUB COMPACT transmits to OBERON C speakers using a proprietary 30 bit wireless protocol derived from the acclaimed DALI SOUND HUB. Audio transmission latency from input to speaker is typically less than 15 mS, and inter-speaker timing is accurate to the single sample period of the broadcast audio data.
PATENTED SMC
The iron pole piece of the OBERON C woofer magnet is crowned by the DALI patented SMC disk - minimizing the negative effects of the iron. The use of the SMC disk greatly reduces mechanical distortion, which lowers third order distortion. This allows for a longer listening pleasure, a relaxed midrange and a surprising amount of detail for its price class.
ACTIVE SPEAKER
The OBERON 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, one powers the bass/mid driver (or twin drivers in the case of the OBERON 7 C).
OBERON ON-WALL C
PRODUCT DETAILS
The OBERON ON-WALL C was designed with TV audio very much in mind and despite its compact dimensions, the combination of DALI technologies employed endow it with performance comparable to significantly larger speakers. The OBERON ON-WALL C is designed specifically for direct wall mounting via rear panel keyhole slots. Portrait and landscape orientations are both accommodated.
The slim and discreet OBERON ON-WALL C comprises a compact, low profile, rear reflex loaded cabinet 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 OBERON ON-WALL C 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 ON-WALL 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. This is also the reason why all DALI speakers are not designed to be toed-in.
FIRMWARE UPGRADE TOOL
WOOFER/SMC
The OBERON ON-WALL C builds on a 5.25" bass/midrange driver that features DALI's proprietary fine paper pulp and reinforced wood fibre composite diaphragm materials, which creates 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 with position. 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.
AMPLIFIER
The OBERON ON-WALL 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 and one powers the bass/mid driver. 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 OBERON ON-WALL C 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 ON-WALL 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.
TWEETER
The OBERON ON-WALL C 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 ferro-fluid in its voice-coil gap.
CABINET
OBERON ON-WALL 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.
The OBERON ON-WALL C incorporates dual, rear panel reflex ports that are configured to exit in parallel alignment with the wall - incorporating the wall and speaker panel in their operation. The ON-WALL C reflex port is a uniquely innovative solution that plays a significant role in enabling the speaker’s unusually shallow depth dimension.
The OBERON ON-WALL C is mounted directly on the wall via rear panel keyhole slots.
