DALI OBERON ON-WALL
The DALI OBERON ON-WALL is a slim, discreet and surprisingly powerful on-wall speaker, which utilises DALI’s unique on-wall bass port system. It houses an oversized 29 mm ultra-lightweight soft dome tweeter together with a 5.25″ SMC based wood fibre woofer and the unique down-firing bass port system, which DALI has perfected. It combines technologies which make it possible to create a speaker that – despite its compact size – will render audio like a much larger model. For this reason, it’s the perfect choice for both stereo and surround setups.
The OBERON ON-WALL is a powerful on-wall speaker with a slim and discreet design. Despite its compact size, the on-wall speaker will render audio like a much larger model, due to its combination of technologies. The slim profile of the speakers makes it easy to integrate into any room.
We have united the best elements from our current speakers and brought them together in the OBERON ON-WALL to deliver on audio quality, looks and versatility. The OBERON ON-WALL houses an oversized 29 mm soft dome tweeter together with a 5.25″ SMC based wood fibre woofer – supported by a unique down-firing bass port design, which lets the OBERON ON-WALL use the wall to extend the bass performance. For this reason, it’s the perfect choice for both stereo and surround setups.
To achieve a wide dispersion pattern in the listening area, the driver materials and geometry applied have been carefully selected. The same principles have been applied in the design of the crossover. As result, you will experience a well-integrated sound, even when listening at a significant off-axis angle. This is important as you are rarely seated directly in front of your loudspeakers when listening to music. An added benefit is seriously reduced harmonic distortion and diffractions causing frequency distortion, as these will always be stronger in an on-axis response. This is also the reason why all DALI loudspeakers are not designed to be toed-in.
The SMC based 5.25″ wood fibre woofer used in the OBERON ON-WALL has been optimised with a new wood fibre structured cone. It is dedicated to reproduce the delicate midrange and bass frequency area. 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 – 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.
With the use of Soft Magnetic Compound (SMC) in the OBERON ON-WALL woofer, mechanical distortion caused by hysteresis and eddy currents is greatly reduced. This improvement in the magnet motor system results in a lowering of the third order distortion. This allows the OBERON ON-WALL 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.
