A taller, slimmer version of a customer favorite

ELAC's Uni-Fi UF5 floor-standing speaker is a hit with our customers. Now ELAC offers the same great performance in a slimmer, taller, and deeper enclosure.

The Uni-Fi F5 U5 Slim uses the same drivers and high-quality crossover elements as its stockier UF5 brother. But its sleek, Euro-inspired design features a high-quality satin painted finish.

ELAC Uni-Fi F5 U5 Slim floor-standing speaker

The ELAC Uni-Fi FS U5 Slim comes with stabilizing floor spikes that provide a firm foundation on thick carpets.

The concentric difference — better sound

The Uni-Fi FS U5 Slim's concentric driver places a 1" soft dome tweeter directly in the center of a 4" aluminum midrange cone.

This precise alignment creates a "unified source," ensuring that all frequencies arrive at your ears at the same instant, producing coherent, accurate sound.  

Clear, accurate bass

The Uni-Fi FS U5 Slim uses three custom-designed 5-1/4" aluminum cone woofers to supply articulate bass that blends in precisely with the concentric driver.

Each woofer sports a large magnet and vented pole piece that increases power handling for bass that's clean, clear, and powerful. Three rear-firing ports extend bass performance, keeping it tight and tuneful.

Product Research


3-Way Speaker Design: The Elac Uni-Fi FS U5 Slim floorstanding loudspeaker employs a 3-way design with a new in-house developed concentric driver. A 3-way speaker offers many advantages in the design of a full-range system. By assigning dedicated drivers to high, midrange, and bass frequencies, each is optimized for the frequency range for which its design and material composition is best suited. The FS U5 Slim floorstanding speaker consists of a concentric midrange-tweeter driver for high and midrange frequencies, while one aluminum-cone woofer handles lower-frequency midbass and bass. At the same time, a 3-way speaker allows for a more straightforward crossover and cabinet design.

Custom-Designed Concentric Driver: The Elac Uni-Fi FS U5 Slim floorstanding loudspeaker employs a concentric driver design, combining the 1" soft-dome tweeter and 4" midrange cone diaphragm within a single voice coil. Because of its ideal time-domain characteristics, a concentric driver design delivers the most coherent and accurate reproduction across the treble and midrange frequency spectrums. 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.

5.25" Aluminum Woofer: In addition to the concentric midrange-tweeter driver, the Elac Uni-Fi FS U5 Slim features one 5.25" aluminum cone 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.

Sophisticated Crossover: One secret to the great sound of the Uni-Fi series loudspeaker is the high quality, audio-grade components specified in the manufacture of each custom, 3-way crossover. This careful 3-way crossover design provides a smooth transition between the high, mid, and bass drivers.

Triple Bass Ports: The Elac FS U5 Slim floorstanding loudspeaker utilizes a bass reflex enclosure with three rear-firing flared ports for greater efficiency and bigger bass response.

Robust MDF Cabinet: The Uni-Fi speaker enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl finish. The Uni-Fi series cabinet incorporates 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.

Note: The Elac FS U5 Slim floorstanding loudspeaker is available in a black or white finish (both come with a black grille).

Magnetic Grille: 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.

Binding Posts: The Elac Uni-Fi series floorstanding loudspeaker is fitted with a set of heavy-duty, binding-post terminals which will accept bare-wire (up to 10AWG), pin-connectors, and banana plugs (single only).

Outrigger Base: 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 spike-feet and protective discs, used according to whether the loudspeaker is placed on a soft or hard floor surface. The protective discs add approximately 0.25" to the overall height of the speaker.

Note: There is a pre-installed safety clip on the back of the speaker cabinet for securing the floorstanding speaker to a wall to prevent tip-over. Wall-mount hook, screws, and cord are all sold separately and can be found at your local hardware store.

Applications: The Elac FS U5 Slim floorstanding loudspeaker can be used in a 2ch stereo application, or used as your front speakers and/or rear surround speakers in a multichannel home theater application.

  • 2Ch Stereo or Front Speaker Placement:  For optimum stereo imaging, place the speakers so that an equilateral triangle is created between the speakers your main listening position. You can also angle ("toe in") the speakers towards the listening position to gain a more focused central image.
  • Rear Surround Placement: In a 5.1-channel surround setup, avoid placing the speakers forward of your listening position. The speakers should be spread apart wider than the front speakers.
Note: In either application, the speaker should be placed 1' to 2' away from boundaries such as wall and corners. Close proximity to a side or rear wall will enhance bass performance, but being too close may result in bass that is unnatural.

Elac Uni-Fi Slim Series: The Elac Uni-Fi Slim series family of loudspeakers consists of a floorstanding loudspeaker, a bookshelf loudspeaker, and a center-channel loudspeaker (all sold separately). All of the Uni-Fi Slim series of speakers feature concentric driver technology. The Uni-Fi Slim series can be the basis of an outstanding two-channel system, or used to build an awe-inspiring multi-channel surround-sound system.

Optional Powered Subwoofer: Add an ELAC powered subwoofer (sold separately) to the Uni-Fi series to bring more bass to your movie and music soundtracks.
