Special Order

The DALI OBERON ON-WALL is a slim, discreet and surprisingly powerful on-wall speaker, utilising 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-enabled wood fibre woofer and the unique down-firing bass port system, perfected by DALI. 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.

  • 5.25" woofer, extra-lightweight soft dome tweeter
  • DALI-Patented SMC woofer driver technology
  • Innovative folded down-firing bass port for maximum bass response from smallest cabinet
  • Smooth and wide sound radiation pattern


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



The rounded edges and rustic fabric of these new DALI front grilles add a lighter and more contemporary visual look to the OBERON series.


The OBERON woofer features a wood fibre cone with a blend of fine grained paper pulp reinforced with wood fibres creating 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 iron pole piece of the OBERON woofer magnet is crowned by a patented SMC disk - minimising the negative effects of the iron. Use of the SMC disk greatly reduces mechanical distortion, which lowers third order distortion. This allows for longer listening pleasure, a relaxed midrange and a surprising amount of detail for its price.


The OBERON ON-WALL is a powerful on-wall speaker with a slim and discreet design. Despite its compact size, the on-wall speaker renders audio like a much larger model, thanks to its combination of technologies. The slim profile of the speakers makes them easy to integrate into any room.

DALI have combined the best elements from their current speakers 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-enabled 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 in the OBERON ON-WALL have been carefully selected and designed. The same principles have been applied in the design of the crossover.

As result, you will experience a well-integrated sound, even when listening significantly off-axis. This is important, as on-wall speakers can hardly be toed in!  Thankfully, all DALI speakers are designed to give their best sound when pointed straight forward.

The 5.25" SMC based woofers used in the OBERON ON-WALL are dedicated to reproducing delicate midrange and bass frequencies. The woofers have been optimised with a new wood fibre structured cone, constructed from a blend of fine grained paper pulp and wood fibres, creating a stiff, light-weight and well-behaving structure. When combined 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 chosen for its soft and very flexible properties. This gives the membrane free movement with a very low dampening effect, and lets the magnet motor and the magnet motor alone control the membrane movement.

With the use of SMC (Soft Magnetic Compound) technology in the OBERON ON-WALL woofers, mechanical distortions caused by hysteresis and eddy currents are 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 give longer listening pleasure with a relaxed midrange and a surprising amount of detailing for the price.

The magnet motor itself consists of a large ferrite magnet sorrounding a pole piece made with a unique combination of iron and SMC. The iron ferrrite forms the lower base of the pole cylinder, and is topped of with a 10 mm SMC disk as the crown. This combination minimises 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 maximum effect from the SMC on the voice coils environment, resulting in a greatly improved constant flux field.

The 29 mm ultra-light soft dome tweeter used is manufactured by DALI and has been developed specifically for the OBERON series -- including the ON-WALL -- combining well-proven technologies from their existing speaker range 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's construction is based on an ultra-light wave weave fabric and is additionally optimised for a larger bandwidth in its lower frequency area. This ensures optimal handover from the 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 around 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.

With its unique bass port design the OBERON ON-WALL takes the use of the rear wall to a whole new level.

Originally conceived and used in the DALI RUBICON LCR, the bass ports on the OBERON ON-WALL fire downwards behind the speakers, allowing maximum use of space and allowing the ports and the wall to work together to extend the bass reproduction far beyond what should be possible from such a compact cabinet.

The cabinet construction of the OBERON ON-WALL is composed from high-density CNC machined MDF board dressed in carefully selected high-grade vinyl. Solid bracings across the inside of the cabinet reinforce the cabinet to very high rigidity. This improves the stiffness and practically eliminates resonance within the cabinet.

The special cabinet design fits the bass port for an appropriately low frequency for this speaker in what seems like an impossibly small space.

DALI have optimised response timing by fitting the speakers 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.

With the OBERON range, DALI introduced a brand new front grille design. The new rounded front grille adds a lighter and more contemporary visual look to the speaker series.
