Dali Oberon On-Wall Speaker

Dali Oberon On-Wall Speaker

The OBERON ON-WALL wall loudspeaker is equipped with an integrated wall bracket. The wall speaker OBERON ON-WALL is extremely flat, unobtrusive and surprisingly powerful in sound. The wall speaker combines Dali's large 29 mm dome tweeter with a 130 mm (5 1/4'') wood-fibre bass/midrange driver and DALI's exclusive downward bass reflex port.

The sophisticated technology of the OBERON ON-WALL allows the assumption of a much larger loudspeaker for music reproduction - which is why this model is recommended as a discreet solution for both stereo and home cinema systems.

SIMPLE PLACING
When designing the drivers and crossovers as well as the materials used, great importance was attached to ensuring a particularly wide dispersion pattern. This means that, without angling the loudspeakers towards the listening position, an extremely three-dimensional sound image that is well integrated into the room can also be achieved outside the classic stereo triangle.

MODERN DESIGN
The rounded corners and the coarse-meshed structure of the fabrics give the front covers of the OBERON loudspeakers a unique design. The two floorstanding loudspeakers also have an elegant, resonance-reducing aluminium base.

WOOD Fiber MEMBRANE
The cones of the mid-bass drivers consist of a mixture of fine-grained paper pulp reinforced by the addition of wood fibres, resulting in a stiff, lightweight structure with excellent acoustic properties. In combination with particularly low-loss beads and centering spiders, the cone diaphragms reproduce even the finest sound details extremely clearly and precisely.

PATENTED SMC
The pole piece of the magnetic systems used in the OBERON mid-bass drivers consists of a combination of iron and the patented magnetic material SMC. Thanks to the significantly reduced third order distortions, the OBERON loudspeakers provide a longer, more relaxed listening experience with unobtrusive mids and a wealth of detail that is astounding in this class.

The Dali Oberon ON-WALL speaker in detail

TIEFMITTÖNER
Like all DALI drivers designed to reproduce the mid and low frequencies, the 130mm (5 1/4'') OBERON ON-WALL1 bass/midrange driver features a wood-fiber cone. The mixture of a fine-grained paper pulp reinforced by the addition of wood fibres results in a stiff, lightweight structure with excellent acoustic properties. In combination with particularly low-loss beads and centering spiders, the cone diaphragm reproduces even the finest sound details extremely clearly and precisely.

The cone is surrounded by a rubber surround which, due to its soft and very flexible material, allows the cone to oscillate absolutely freely, has very low damping and the magnet system allows the cone movement to be controlled very precisely.

SMC
The use of SMC in the magnet system significantly reduces mechanical distortions caused by hysteresis and eddy currents. In combination, these magnetic drive improvements significantly reduce third-order distortion, which is why OBERON Series speakers deliver a longer, more relaxed listening experience with unobtrusive mids and an amazing level of detail in this class.

The drive consists of a large ferrite magnet enclosing a pole piece made of a unique combination of iron and SMC. SMC is a magnetic powder that makes it possible to form strong magnets that do not conduct electricity. Since the ferrite iron only forms the base of the pole piece, the negative effects of the iron are minimized, while the 10 mm thick SMC disc is placed on top of the pole piece right in the center of the main working area of the four-layer voice coil. This guarantees the maximum effect of the SMC on the voice coil environment, resulting in a greatly improved constant flux field.

HIGH TONE
The tweeter with its ultra-light fabric dome 29 mm in diameter was specially developed for the OBERON series. The cone is made of an extremely lightweight fabric that weighs less than half as much as most other dome tweeters on the market, at just 0.060 mg per mm2.

Thanks to the large diaphragm, the tweeter achieves a higher sound pressure level at a lower excursion, which means that the voice coil can always move with extreme precision and control. The tweeter's magnet system is cooled with ferrofluid to provide higher power handling, perfect damping and support for absolutely centred voice coil excursion.

The extremely light dome tweeter manufactured by DALI is also optimized for a wider bandwidth in its lower frequency range. This ensures a seamless transition from bass-midrange to tweeter with a balanced, airy and very harmonious reproduction of the upper midrange.

The front panel of the tweeter is designed similar to the OPTICON and RUBICON series in order to create optimum working conditions for the fabric dome with regard to a wide frequency response, a very wide angle radiation and as little discoloration as possible.

BASSREFLEX OPENING
The OBERON ON-WALL uses the bass reflex system that was originally introduced with the RUBICON LCR and was specially developed for flat wall loudspeakers. The unique design with a reflex opening radiating along the rear of the cabinet allows a powerful and deep bass reproduction with the support of the wall, which was previously not possible with such compact loudspeakers.

BODY
The OBERON ON-WALL cabinet consists of CNC-milled MDF panels coated with carefully selected, high-quality vinyl foils, providing a solid base for mounting the loudspeaker chassis.

In the interest of optimum timing, all the inside of the cabinet - with the exception of the back of the baffle - is lined with acoustic insulation material. This ensures more direct contact between the woofer and the bass reflex port, resulting in a more precise bass and an open, highly transparent midrange.

The bass reflex ports are located at the rear of the cabinet to ensure the strongest possible bass response by supporting the sound waves reflected from the wall behind the speakers.

The front covers of the OBERON series have also been redesigned. The elegant rounded covers, covered with a specially textured fabric, give the loudspeakers an extremely pleasing and modern look. The brighter white and light oak cabinet versions are supplied with grey mottled front covers, while the darker black and walnut cabinets are supplied with black covers. A white version is also available as an optional accessory.
