ELAC Uni-Fi BS U5 Slim 3-Way Bookshelf Speakers (Satin Black, Pair)

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.

Uni-Fi Slim Features

Custom-designed concentric driver
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.

Beautiful, furniture-quality finish
The other difference that distinguishes Uni-Fi Slim is the elegant matte satin paint finish of the outer cabinets. Instead of being wrapped in black brushed vinyl, Slim upgrades the appearance and feel with a durable surface as elegant as it is durable.

Robust cabinets
The Uni-Fi Slim enclosures are narrower, taller and deeper than the original Uni-Fi series, engineered for the long run with thick MDF outer walls. Yet each has been carefully engineered to maintain the same internal volume, resulting in sonic characteristics indistinguishable from the originals. The cabinets incorporate specially designed internal bracing to add stiffness and strength to the cabinet’s outer walls. This bracing greatly reduces cabinet vibration, which causes unwanted coloration to the sound. ELAC believes that the only parts of a speaker that should be moving are the speaker drivers themselves.

Sophisticated crossover
One secret to the great sound of the Uni-Fi Slim series are the high quality, audio-grade components specified in the manufacture of each custom, three-way crossover, the careful design of which is essential to smooth transition between the drivers. The best crossovers are the ones in which the sonic landscape—from lowest fundamentals to highest highs—becomes seamless. This is the sound of Uni-Fi.

Sophisticated aluminum woofer
Through the use of aluminum, resonances that affect the linearity of common paper cones can be placed beyond the driver’s operating frequency range. An extended size magnet with vented pole piece increases power handling, for accurate reproduction of bass frequencies that are clean, clear and powerful.

Custom-designed binding posts
The custom terminals provide flexibility of speaker wire connections and ensure optimal electron transfer from speaker cables to the speaker itself. Details like this make the difference!
