The DALI OBERON 1 is a ultra compact bookshelf speaker. The cabinet size enables an optimal balance between inner volume for bass performance and a compact appearance for easy integration - suited for smaller rooms, discreet audio setups or wall mounting. It features the same oversized 29 mm ultra-lightweight soft dome tweeter as its floor-standing siblings, and a SMC based 5.25" wood fibre woofer to handle lower midrange and bass. The OBERON 1 is based on the most innovative DALI ideas, traditions and inventions - united in a sleek compact design. 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. - Frequency Range (+/-3 dB) [Hz]: 51 - 26,000

The M-1 has been engineered with the same design attributes and ethos as B&Wʼs larger ranges. Perhaps the most striking thing about the M-1 is the weight and strength of its curved aluminium cabinet. This is combined with a strong, glass-loaded ABS front baffle. Together they provide an excellent cabinet: the curved aluminium is stiff and the ABS offers excellent and appropriate damping characteristics.
The M-1ʼs drive units were developed by Bowers & Wilkins specifically for the design. The metal dome tweeter benefits from refinements developed for the new B&W 800 Series and includes Nautilus™ tube loading and neodymium magnets. The glass fibre bass/midrange coneʼs ability to absorb standing waves has been further enhanced by the inclusion of five strategically placed resin filled slots that further minimise distortion.
The result of this detailed cabinet and drive unit engineering has allowed B&Wʼs engineers to borrow another feature from the new 800 Series and utilise the simplest of electronic equalisation in the M-1ʼs crossover. Each of the drive units is fed by only a single, carefully selected component. This approach to crossover design, although painstaking as it relies on optimising all of the physical components in a design, is crucial in achieving its aim of neither adding to nor subtracting from the original signal.
The M-1 is available in three colour options - black, white and silver, each with chromium plated stem and table base.

At home on a stand, wall or bookshelf, the versatile 685 S2 is ideal for stereo and home theatre uses in most rooms. And performance is enhanced with the addition of a Decoupled Double Dome tweeter.
The Decoupled Double Dome tweeter found in the 685 S2, and the rest of the new 600 Series, is technology taken straight from our award-winning CM10 speaker. A dual-layer design combines a thin aluminium dome for lightness and a thicker aluminium ring for rigidity - the result is absolutely stunning, with far greater clarity in the audible spectrum.
The tweeter is also decoupled from the main cabinet, kept physically separate in its own cavity with a ring of gel cushioning it from vibrations. This improves imaging and dispersion for a more natural, spacious treble.
As well as a decoupled, double dome aluminium tweeter, the two-way 685 S2 features a full-range 6.5-inch driver constructed from woven Kevlar and using Anti-Resonance Plug dustcaps, as seen in high-end Bowers & Wilkins speakers. The result is stunning audio quality from a highly versatile smaller speaker.
