Dali Oberon On-Wall C Compact Loudspeaker

Flexible setup

The chassis and crossovers used in the OBERON C series are designed to radiate the audio signals over a particularly wide angle. This not only enables rich, spatially precise reproduction outside the sweet spot, but also significantly reduces harmonic distortion and diffraction that impair the sound.

Low latency

The audio signals are transmitted from the SOUND HUB COMPACT to the OBERON C loudspeakers using a proprietary 30-bit wireless protocol. The latency from the input to the loudspeaker is usually less than 15 ms, and both loudspeakers are controlled at exactly the same time.

Patented SMC technology

The pole piece of the magnet system of all OBERON C woofers is partly made of the non-conductive Soft Magnetic Compound (SMC) magnet material patented by DALI. The use of SMC significantly reduces mechanical distortion, which means that the speakers sound very pleasant even over longer periods of time and surprisingly detailed considering their price range.

Active speakers

Each OBERON C loudspeaker uses two Class D amplifiers with an impulse line of 50 watts each, which were selected for their high sound quality and dynamics. One amplifier supplies the tweeter, one the woofer (or the two woofers in the OBERON 7 C).

Description

When developing the OBERON ON-WALL C, the focus was on combining it with a TV, as the flat wall speakers can be perfectly placed next to a flat screen thanks to the keyhole slots integrated into the rear wall. Despite its compact dimensions, the combination of the DALI technologies used gives it a performance and sound quality that is comparable to much larger speakers. The speakers can be operated in both portrait and landscape format.

The OBERON ON-WALL C's housing, which is only 12 cm deep, is fitted with an ultra-light 29 mm fabric tweeter and a 130 mm woofer with DALI's own wood fibre membrane and SMC technology. A unique bass reflex system integrated into the rear supports the chassis in bass reproduction.

The compact OBERON ON-WALL C can be easily integrated into any room. Its wide dispersion characteristics allow unrestricted listening pleasure even outside the sweet spot directly opposite the speakers.

The OBERON ON-WALL C receives the digital audio signals wirelessly from a SOUND HUB COMPACT or SOUND HUB with a resolution of 24 bit and 96 kHz.

Note: If you want to stream music or radio programs from the Internet or integrate the OBERON C speakers into a multi-room system, the DALI SOUND HUB including BluOS module is the right control unit for you.

woofer/midrange driver/SMC

The diaphragm of the 130 mm OBERON ON-WALL C woofer-midrange driver is made from our proprietary material mix; a composite of paper pulp and wood fibers. An advanced copper-coated aluminum wire is used for the voice coil.

Our unique SMC magnet technology (SMC = Soft Magnet Compound) is worth highlighting. By using electrically non-conductive elements in the magnet structure, SMC reduces the effects of various distortion-generating properties of the voice coil design. For example, SMC reduces eddy current effects, increases flux linearity, reduces magnetic hysteresis and minimizes the position-related variation of the voice coil inductance. In summary, drivers equipped with SMC are particularly suitable for active loudspeaker systems.

The membrane is surrounded by a rubber surround, which was chosen for its soft and very flexible properties. This allows the membrane to move freely, is only dampened to a very small extent and allows the magnetic drive to control the membrane movement.

amplifier

The OBERON ON-WALL C has two regulated Class D power amplifiers, each with 50 watts of peak power, which were selected for their sound quality and dynamics. One amplifier supplies the tweeter, one the woofer. A signal-to-noise ratio of 100 dB ensures that these power amplifiers can reproduce even the smallest details of a quiet musical passage transparently and precisely.

The electronics module mounted on the back of the OBERON ON-WALL C contains the radio receiver unit, the user interface for the setup, the DSP for the equalization and crossover as well as the powerful two-channel power amplifier.

The amplifiers are powered by a specially developed switching power supply that can dynamically allocate its resources to the two amplifier channels as required. The OBERON ON-WALL C is therefore unusually economical in terms of power consumption, without compromising dynamics when it is needed.

tweeter

The tweeter of the OBERON ON-WALL C is equipped with a particularly light and unusually large dome with a diameter of 29 mm. Thanks to the light membrane, the driver covers a particularly wide frequency range. The large diameter of the membrane and voice coil increases sensitivity and power handling while reducing distortion. This means that the driver can also cover lower frequencies than smaller tweeters, which in turn gives more scope when designing the crossover. Ferrofluid in the voice coil gap serves to increase power handling and reduce signal compression when the temperature of the voice coil increases at higher volumes.

Housing

The housing of the OBERON ON-WALL C is made of CNC-milled high-strength MDF panels. They are covered with various laminates in wood look or matt white. The housings are designed for optimal rigidity to minimize the resonance of the panels, the corners are rounded.

The OBERON ON-WALL C's internal enclosure damping materials are strategically selected and positioned to maximize mid-range energy attenuation without compromising bass transient response and bandwidth.

The OBERON ON-WALL C has two bass reflex ports in its rear panel, which are designed to discharge air parallel to the wall, taking the wall and the speaker cabinet into account in the system. The reflex ports on the ON-WALL C are a unique, innovative solution that plays a key role in enabling the speaker's unusually flat dimensions. Keyhole slots integrated into the rear panel allow the speakers to be easily hung directly on the wall.
