Details from Elac

    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 within the Uni–Fi BS U5 Slim bookshelf speakers in White. 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.

    Balanced three–way design

    A three–way speaker offers many advantages in the design of a full–range system. By assigning dedicated drivers to high, mid– and bass frequencies, each is optimized for the frequency range for which its design and material composition is best suited. Drivers like the groundbreaking concentric midrange–tweeter of the Uni–Fi Slim series perform at their best, while larger, aluminum–cone woofers handle the frequency ranges in which they perform best. At the same time, a three–way speaker complement allows for a more straightforward crossover and cabinet design, eliminating complex and costly solutions.

    Elegant cabinets

    The White Uni–Fi BS U5 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.

    Beautiful, furniture–quality finish

    The other difference that distinguishes Uni–Fi Slim is the elegant matt–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.

    High quality base and feet

    An outrigger base design used for the FS U5 Slim provides a larger, more stable footprint and adds stability and optimum coupling of the speaker cabinet to the floor. Molded knobs dial in precise leveling of the four corners, which are supplied with metal spikes and spike stands, used according to whether the loudspeaker is placed on a soft or hard floor surface.

    Sophisticated crossover

    One secret to the great sound of the Uni–Fi BS U5 Slim 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!
