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.
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.
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.
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.
