ELAC Uni-Fi BS U5 Bookshelf 2-way Speaker (Pair – Satin White)

Beauty and the bookshelf.

Space constraints should never compromise great sound, and the Uni-Fi BS U5 Slim is the perfect solution when floor space is at a premium, but audiophile sound and refined good looks are not negotiable. Using the same outstanding driver and crossover components of its bigger brother, this compact, 3-way, bass-reflex monitor delivers the sonic signature of Uni-Fi in a smaller package.

Uni-Fi Slim are the latest additions to the Uni-Fi family of bookshelf, floorstanding and center-channel speakers. The Slim series brings a sophisticated European flair to Uni-Fi, with cabinets that are slimmer, taller and deeper than the originals. And each comes in a high-quality satin painted black or white finish to complement the most elegant décor.

Like the originals, each model in the Slim series is designed by Andrew Jones, and employs the same concentric driver responsible for the award-winning sound of Uni-Fi. Ideal time-domain characteristics result from combining a tweeter and midrange diaphragm within a single voice coil—delivering the most coherent and accurate reproduction across the treble and midrange frequency spectrums. Importantly, Uni-Fi Slim sounds exactly the same as Uni-Fi, employing an identical driver complement, crossover, internal cabinet structure and volume. Only the shape and cabinet are even more refined, featuring a smaller footprint and smooth, satin finish.

ELAC’s chief engineer Andrew Jones explains how Uni-Fi Slim speakers are built on the same foundation: “My goal with the original Uni-Fi series was to create a line of speakers with technology and performance normally reserved for speakers costing significantly more, by going with a 3-way design and employing a new in-house developed concentric driver. With Uni-Fi Slim, design-conscious listeners can enjoy the same outstanding sound along with more elegant proportions ad slim, high-quality cosmetics.”

Uni-Fi Slim can be the basis of an outstanding two-channel system, or used to build an awe-inspiring multi-channel surround-sound system. Add an ELAC subwoofer for the last word in music and movie soundtrack reproduction.

The delicacy of a 1-inch soft-dome tweeter and the harmonic accuracy of a rigid aluminum 4-inch midrange cone come together in a symphony of sonic perfection. Positioning the tweeter concentrically within the midrange voice coil achieves a uniform directivity pattern, for flat frequency response and formidable power handling, along with enhanced imaging for both on- and off-axis listening positions.

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.
