Dali Oberon Vokal Center Speaker

EASY TO POSITION

The driver materials, crossover design and geometry applied in the OBERON 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.

CONTEMPORARY DESIGN

The rounded edges and rustic fabric of these new DALI front grilles add a lighter and more contemporary visual look to the OBERON series. This look is enhanced by the elegantly shaped aluminium base mounted on the two floor-standing models.

WOOD FIBRE CONE

The OBERON woofer features a wood fibre cone with a blend of fine grain paper pulp, reinforced with wood fibres, 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.

PATENTED SMC

The iron pole piece of the OBERON woofer magnet is crowned by a 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.

WOOFER

The 2 x 5.25" SMC based woofers used in the OBERON VOKAL are dedicated to reproduce the delicate midrange and bass frequency area. The OBERON woofers have been optimised with a new wood fibre structured cone, which is constructed from a blend of fine grain paper pulp reinforced with wood fibres. This creates a stiff, light-weight and well-behaving structure - like every other driver made by DALI.

In combination with a low-loss surround and spider suspension, the wood fibre cone reproduces the micro details in the signal - unfiltered and with high accuracy.

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.

SMC

Mechanical distortion caused by hysteresis and eddy currents is greatly reduced due to the use of Soft Magnetic Compound (SMC) in the OBERON VOKAL woofer. This improvement in the magnet motor system results in a lowering of the third order distortion. This allows the OBERON VOKAL to present longer listening pleasure with a relaxed midrange and a surprising amount of detailing for the class.

The magnet motor itself consists of a large ferrite magnet that sorrounds a pole piece made with a unique combination of iron and SMC. The iron ferrrite forms the lower base of the pole cylinder, topped of with 10 mm SMC disk to crown the pole piece. This combination minimizes the negative effects of the iron, while placing the SMC disk right in the main working area of the 4-layer voice coil. This placement ensures the maximum effect from the SMC on the voice coils environment, resulting in a greatly improved constant flux field.

TWEETER

The oversized 29 mm ultra-lightweight soft dome tweeter was specifically developed for the OBERON series - including the OBERON VOKAL - combining well proven technologies from our existing DALI ranges with new features.

The large size of the membrane lets the tweeter generate higher sound pressure with less excursion, keeping the voice coil motion to a precise minimum.

The oversized 29 mm membrane is constructed based on an ultra-light wave weave fabric and is additionally optimised for a larger bandwidth in its lower frequency area. This ensures the optimal handover from the midrange woofer to the tweeter, creating a well-balanced, unforced and very coherent upper midrange. Compared to most soft dome tweeters in the market, the DALI dome material is less than half the weight (0.060 mg/mm2).

The tweeter front plate near the dome has been designed with similar geometry as the OPTICON and RUBICON tweeters to create the optimal working conditions for the soft dome. The aim is to combine an extended frequency response with wide dispersion and low coloration.
