Dali ZENSOR 7 Floorstanding Loudspeaker

Dali Oberon 3 Kompaktlautsprecher

The Dali OBERON 3 is an outstanding compact loudspeaker. The Dali Oberon 3 convinces with its 29 mm dome tweeter and the 180 mm (7'') bass midrange driver with wood fibre cone and SMC magnet system with impressive treble, detailed and crisp mid-range as well as an astonishingly deep and precise bass. Accordingly, the Dali Oberon 3 with its great sound is reminiscent of a full-blown floorstanding loudspeaker. This makes the Dali OBERON 3 compact loudspeaker the perfect choice for placement on speaker stands, on a shelf or on a sideboard.

This is made possible by the comparatively large diaphragm area of the two OBERON 3 drivers and their particularly wide-angle dispersion characteristics. While shelf speakers of comparable size are usually equipped with 165 mm woofers and a 19 or 20 mm dome tweeter, the OBERON 3 uses a 180 mm woofer-midrange driver and a 29 mm dome tweeter. Thanks to the approximately 15 % larger diaphragm area, the drivers can generate a certain sound pressure level with a significantly lower excursion. Therefore the OBERON 3 sounds extremely dynamic on the one hand, on the other hand it sets any kind of music or film soundtrack comparatively easy and more pleasant for the ear in scene.

DALI Oberon 3 - The solution for rich sound despite limited space

TIEFMITTÖNER
Like all DALI drivers designed to reproduce mid and low frequencies, the 180 mm (7'') OBERON 3 bass/midrange driver also features a wood fibre 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 cone reproduces even the finest sound details extremely clearly and precisely.

With a diameter of 180 millimetres (7''), the OBERON 3's bass-midrange drivers are considerably larger than the 165 mm drivers mostly used in loudspeakers of this price class. Thanks to the approximately 15 % larger diaphragm area, the drivers can generate a certain sound pressure level with a significantly lower excursion. However, larger diaphragms not only mean a higher sound pressure level, but also - and this is far more important - a more effortless reproduction of the music in its full dynamic range.

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.

DER HOCHTÖNER
The tweeter with its ultra-light, 29 mm diameter fabric dome 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 larger 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.

SMC
The use of SMC in the magnet system significantly reduces mechanical distortion 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.

THE CASE OF THE DALI OBERON 3
The cabinet of the OBERON 3 consists of CNC-milled MDF boards, which are coated with carefully selected, high-quality vinyl foils and thus form a solid basis for the assembly of 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 lighter cabinet versions white and light oak are supplied with grey mottled front covers, the darker cabinet colours black and walnut are supplied with black covers. A white version is also available as an optional accessory.
