Elac Uni-Fi UB5
3 way Dual Concentric Loudspeakers
Elac Uni-Fi UB5 bookshelf loudspeakers employ a concentric driver. Because of its ideal time domain characteristics, a concentric design, combining a tweeter and midrange diaphragm within a single voice coil, delivers the most coherent and accurate reproduction across the treble and midrange frequency spectrums. Because of their high cost, concentric drivers are traditionally used in only the most expensive speakers.
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 optimised for the frequency range for which its design and material composition is best suited. Drivers like the ground breaking concentric midrange-tweeter of the Elac Uni-Fi series perform at their best, while larger, aluminium 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.
Custom designed concentric driver
The delicacy of a 1-inch soft-dome tweeter and the harmonic accuracy of a rigid aluminium 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.
Every Uni-Fi enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl finish. The Uni-Fi 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 colouration to the sound. ELAC believes that the only parts of a speaker that should be moving are the speaker drivers themselves.
One secret to the great sound of the Uni-Fi 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 high, becomes seamless. This is the sound of Uni-Fi.
Sophisticated aluminium woofer
Through the use of aluminium, 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 and magnetic fabric grills
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! When the protective grille is removed, hidden magnets beneath the surface of the cabinet keeps the front panel free of attachment holes, for a clean appearance.
