The DALI OBERON 5 is the ultimate performer – combining DALI ideas, traditions and inventions. It’s a compact and elegant floor-standing speaker, housing 2 x 5¼” wood fibre based woofers with SMC and the series’ wide bandwidth 29 mm ultra-lightweight soft dome tweeter. This slim floor-stander will surprise with its ability to deliver a deep firm bass together with a clear and well defined mid-range and airy high frequencies. The OBERON 5 will impress with its natural and lifelike reproduction of any music or movie sound track.
The OBERON 5 cabinet employs a very rigid construction, with solid bracings across the inside of the cabinet for reinforcement. This contributes to the stiffness and practically eliminates resonance within the cabinet. The cabinet housing of the OBERON 5 is constructed from high-density CNC machined MDF board – dressed in carefully selected high-grade vinyl.
To optimise timing, the speakers are fitted with acoustic damping material internally along the sides, top and bottom. This creates a more direct contact between woofer and bass port. The audible result is a more precise bass and increased ‘attack’ in the midrange.
The bass ports are placed on the rear of the OBERON 5, optimising room integration by utilising the wall for improved bass performance.
With the OBERON range, DALI introduces a brand new front grille design. The new rounded front grille adds a lighter and more contemporary visual look to the speaker series. ‘Mountain Grey’ is the standard grille supplied with the light finishes (White and Light Oak), while ‘Shadow Black’ is standard on the dark finishes (Black Ash and Dark Walnut). For an all white look, ‘Marshmallow White’ is also available as an accessory.
The elegantly shaped aluminium base gives the floor-standing OBERON 5 a lighter look.
The use of SMC in the OBERON 5 greatly reduces mechanical distortion caused by hysteresis and eddy currents. These combined improvements in the magnet motor system results in a lowering of third order distortion. This allows the OBERON 5 to present longer listening pleasure, 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.
The OBERON 5 features a pair of 5.25″ low-loss woofers that are optimised with a new wood fibre structured cone which is dedicated to reproduce the delicate midrange and bass frequency area – like every other driver made by DALI. It is constructed from a blend of fine grain paper pulp and 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.
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.
The brand new 29 mm ultra-light soft dome tweeter used in the OBERON 5 is manufactured by DALI and has been developed specifically for the OBERON series – combining well proven technologies from our existing DALI ranges with new features.
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 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 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.
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.
