Introducing the ELAC Uni-Fi series. It’s what happens when Andrew Jones accepts the challenge of creating loudspeakers that deliver the value of Debut in an even higher-performance package. For the rst time in ELAC’s history, the superiority of a concentric driver comes to an a ordable family of loudspeakers.
ELAC’s chief engineer explains how Uni-Fi speakers build on a new foundation: “My goal with the Uni-Fi series was to create a line of speakers with technology and performance normally reserved for speakers costing signicantly more. By going with a 3-way design and employing a new in-house developed concentric driver, I’ve achieved a sound that is more true to the music than similar priced products.”
Because of its point source characteristics, a concentric design, combining a tweeter and midrange diaphragm into a uni ed source—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 more expensive systems. All three Uni-Fi models—bookshelf, oorstanding and center-channel—can be the basis of an outstanding 2-channel system or used to build an awe-inspiring multi-channel surround-sound system. Add an ELAC subwoofer to rock your world of music and movies like you have never imagined.
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 at frequency response and formidable power handling, along with enhanced imaging for both on- and o -axis listening positions.
5.25-inch Aluminum Woofers
With aluminum, resonances that a ect 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.
High quality, audio-grade components speci ed in the manufacture of each custom, three-way crossover ensure smooth transition between the drivers.
Every Uni-Fi enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl nish. Specially designed internal bracing adds stiffness and strength to the cabinet’s outer walls, reducing cabinet vibration that causes unwanted coloration.
Magnetically Attached Grilles
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.
