3-Way Speaker Design: The Elac Uni-Fi BS U5 Slim bookshelf 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 BS U5 Slim bookshelf 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 BS U5 Slim bookshelf
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
5.25" Aluminum Woofer: In addition to the concentric midrange-tweeter
driver, the Elac Uni-Fi BS 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.
Bass Port: The Elac BS U5 Slim bookshelf loudspeaker utilizes a
bass reflex enclosure with one rear-firing flared port 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
Note: The Elac BS U5 Slim bookshelf loudspeaker is
available in a black or white finish (both come with black grilles).
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 bookshelf
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
Applications: The Elac Debut BS U5 Slim bookshelf 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. In addition,
try to elevate the speakers to the same height or slightly higher as the
front speakers for the most enveloping soundfield.
Note: In either application, the speakers 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.
Mounting Options: The Elac BS U5 Slim bookshelf loudspeaker can
simply be placed on a flat surface; like a table-top, stand, or shelf. The
bookshelf speaker does not offer any wall-mount options.
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.
