Dolby Atmos Loudspeaker: The Elac Debut A4 has been
specifically designed to be used as the "elevation" or "height" speaker in a
Dolby Atmos system from 5.1.2 to 7.1.4. The A4's constructions & performance
characteristics follow the strict guidelines set by Dolby in order to deliver a
true Dolby Atmos experience. The Elac Debut A4 fires sound toward the ceiling
which is then reflected to the main listening area to create the height
information embedded into Dolby Atmos soundtrack.
Dolby Atmos takes surround sound to a completely new level, by adding the
third dimension of height to the two dimensional front/back left/right 5.1 or
7.1 sound mix. In Dolby Atmos, the floor speakers create the sound "bed" and the
Dolby Atmos enabled elevation speakers are fed a separate, discrete signal to
move "sound objects" around the room with pinpoint accuracy. The effect is
totally convincing, and really elevates the home cinema experience to new
Note: A Dolby Atmos AV receiver or processor (sold separately)
will be required for Dolby Atmos surround.
Two-Way Coaxial Driver Design: The Elac Debut A4 Dolby Atmos
enabled loudspeaker features a two-way coaxial driver design with a 0.5"
tweeter, 4" woofers, and a 2,000Hz crossover. The tweeter is positioned in
the center of the woofer cone. Both the tweeter and woofer have
been custom designed by Andrew Jones to deliver an exceptional audio experience
that can't be delivered with typical off-the-shelf parts
- Polymer Dome Tweeter: The Debut A4 features a coaxially mounted
0.5" polymer dome tweeter for crisp, clear highs.
- Woven-Aramid Fiber Woofer: The Dolby Atmos enabled
speaker features a single 4" woven aramid-fiber cone woofer with rubber
surround, oversized magnet, and vented pole piece. Woven aramid fiber offers
a superior stiffness-to-weight ratio and damping over common polypropylene
or paper cones. The added strength allows more flexibility in design to
achieve a smoother, extended frequency response.
- Custom Crossover: A custom seven-element crossover
(2,000Hz) with audio-grade components is implemented to ensure smooth
transition between the tweeter and woofer.
Acoustic Suspension MDF Cabinet: The Elac Debut A4 Dolby
Atmos enabled loudspeaker uses an acoustic suspension (sealed) cabinet for
tight, accurate midbass performance. The cabinet is made of MDF (Medium Density
Fiberboard), helping minimize unwanted vibrations that can discolor music or
movie content. The MDF outer walls of the cabinet are covered with a textured
vinyl black finish. Detachable metal grilles are included.
5-Way Binding Posts: The Elac Debut series A4 is fitted with
a set of 5-way binding-post terminals which will accept bare-wire (up to 10AWG),
pin-connectors, spade-lugs, and banana plugs (single or dual).
Applications: The Elac Debut series A4 can be used in 5.1.2, 5.1.4,
and 7.1.4 Dolby Atmos configurations. Make sure to following mounting,
placement, and room requirements for best performance.
- Mounting Options: The A4 is designed to set on top of
the Debut Elac B5/B6 bookshelf or F5/F6 floorstanding loudspeakers, matching
perfectly. It can also be used with other brands of conventional bookshelf
or floorstanding speakers that feature a flat top-panel on the speaker
- Placement: For optimal effect and to minimize direct radiating
audio at listener level, place the Dolby Atmos enabled speakers at or slight
above the height of your ears when seated. Avoid placing the Dolby Atmos
enabled speakers higher than one-half the height of your wall. The Dolby
Atmos enabled speakers should be placed no closer than 3' from the main
listening position; ideally they should be positioned 5' or more away.
- Room Height: For optimal performance, the ceiling should be flat,
(not angled or vaulted), with a height of 14' or less, and made of an
acoustically reflective material; such as drywall, plaster, or hardwood. The
ideal ceiling height is between 7.5' and 12'. Sound-absorbing and
sound-diffusing treatment for handling unwanted reflections from the walls
and floor is recommend to improve sound quality and system performance.
Elac Debut Series: The Elac Debut series family of loudspeakers
consists of two bookshelf speakers, two floorstanding speaker, a center-channel
speaker, a Dolby Atmos enabled speaker, and two powered subs.
