Two-Way Bookshelf Loudspeaker: The Dynaudio Emit M20
bookshelf loudspeaker utilizes a two-way driver design with a 1.1"
precision-coated, silk soft-dome tweeter and one 6.6875" Magnesium Silicate Polymer (MSP) woofer
for greater precision, power-consistency and control. The Emit M20 delivers a
natural midrange character, exceptionally detailed and clear high frequency
reproduction, and accurate bass performance with incredibly low distortion.
Precision-Coated Soft-Dome Tweeter: Dynaudio has relied on a silk
soft-dome tweeter for recreating high frequencies since the company was
founded, continuously improving and perfecting the soft-dome principle over
the years. Dynaudio tweeter designs require a time consuming,
labor-intensive manufacturing process where the fine fabric diaphragm is
shaped into a dome and is then treated with a specially formulated coating.
As a further refinement, the tweeter's aluminum voice-coil is suspended in a
magnetic oil, which increases power handling while also improving the dome's
excursion. The result is the celebrated Dynaudio tweeter, featuring a
balanced and natural frequency response.
- Damping Chamber: The tweeter includes a special damping
chamber integrated into the rear of the construction, deadening any
back-wave energy through an acoustic absorber. The advantages include high
power handling and unimpeded excursion of the soft-dome dome tweeter.
- Ferrofluid Magnet: The voice coil is positioned within the
magnetic field of the tweeter magnet. When the loudspeaker reproduces
sound, the voice coil, powered by the amplifier current, moves at a
speed of up to 25,000 waves per second. To achieve a uniform movement, a
magnetic fluid called ferrofluid is used around the voice coil.
Ferrofluid works like a subtle shock absorber and eliminates excess
energy. Due to the relatively high current and extremely fast movements,
the voice coil is under constant thermal stress. The ferrofluid
dissipates this heat, while also increasing power handling capabilities.
The frequency range of the tweeter can thus be expanded while the
frequency response remains smooth and linear, delivering the highest
resolution and most neutral sound reproduction.
Note: The surround of the tweeter is inversed to improve
dispersion. This leaves nowhere for the lead wires to go behind the tweeter, so
the lead wires are positioned above the surround.
Magnesium Silicate Polymer (MSP) Woofer: For bass and
midrange drivers, the Dynaudio uses a proprietary composite of magnesium
silicate polymer (MSP), a material that combines low mass, high rigidity,
and ideal internal damping properties. This exclusive driver membrane is an
immediately visible and characteristic feature of Dynaudio loudspeakers.
Formed in a special manufacturing process, this membrane is a unique design
with the distinctive, geometrically optimized form of the cone further
enabling smooth sound dispersion.
- Aluminum Voice Coil: A distinct and major Dynaudio
innovation is the use of pure aluminum wire for voice coils. In
comparison to the more commonly used and much heavier copper
alternative, aluminum allows for more windings and extraordinarily large
diameter coils that remain extremely light. By using aluminum instead of
copper for a bass driver, it is possible to effectively double the
coil's diameter without increasing its mass. Due to the thermal
properties of aluminum, cooling of the voice coil is dramatically
improved as well. In combination with the equally light voice coil
former and powerful magnet materials used in Dynaudio designs, cone
excursion is much more controlled and the driver follows the music
signal from the amplifier with a remarkable sense of dynamics and
- Die-Cast Aluminum Basket: The Dynaudio MSP woofer utilizes a
low-resonance, highly warp-resistant basket made of die-cast aluminum.
Due to the stiffness of this non-magnetic material, the basket can be
designed with aerodynamically formed ribs to reduce air compression
behind the moving membrane. Another advantage is its long-term
resistance against thermal, mechanical or other external influences.
High-Quality 1st Order Crossover: Only the highest quality components,
selected for their sonic properties, are utilized in Dynaudio loudspeaker's
crossover network; carefully wound pure OFC (oxygen-free copper) air-coils,
select capacitors, and temperature-stable ceramic resistors. The Dynaudio
crossover features a pure 1st order filter (6 dB/octave), which enables a superior
transient response and can only be effectively used with the ultra-linear
frequency response of the Dynaudio drivers.
Dynaudio Directivity Control (DDC): With Dynaudio Directivity Control
(DDC), Dynaudio has created a technology that effectively reduces the negative
effects of reflections from floor and ceiling boundaries in a room. The vertical
symmetrical driver array and elaborate crossover topology of a Dynaudio
loudspeaker reduce the energy dispersed to the floor and ceiling by
approximately 75%. The controlled vertical
dispersion makes the loudspeaker far less dependent on the room and much less
influenced by positioning as compared to conventional designs. DDC isn't simply
arranging the drivers in a symmetrical array. For DDC to succeed, every single
detail (from each drive unit to the crossover) must be individually tailored and
optimized for this concept. Each driver needs to complement its identical
counterpart in frequency response and phase relationship in such a manner that a
carefully defined dispersion characteristic is achieved. This intricate matching is repeated once again for each loudspeaker pair to work together in tandem.
Rigid Bass Reflex Cabinet: The Emit M20 bookshelf features a
bass reflex enclosure with a rear-firing port for greater efficiency and bigger
bass response. The Danish tradition of craftsmanship drives the meticulous
process of selecting the perfect cabinet for the combination of custom drivers. The front-baffle
is manufactured using CNC
(Computerized Numerical Control) machining. Computer-programmed and controlled
by ultra-responsive sensors, precision to within a single micrometer (ìm), multi-axial drilling machines produce the acoustically optimized baffle shape
and unique design details. Additional internal damping, strengthening, and
bracing in critical sections of the cabinet substantially reduce unwanted
Note: To minimize low frequency reflections, which
will be heard as a thickening of the sound, the loudspeaker can be adapted
to the room's acoustic character by using the included foam plug in the bass
reflex port. This will essentially attenuate the room induced boost in the
low frequency range by dampening the deep frequencies, yielding a more clear
and tight sound when the loudspeaker is positioned near rear walls.
Heavy-Duty, Gold-Plated Binding Post: The Dynaudio Emit M20 bookshelf
loudspeaker is outfitted with a set of heavy-duty, gold-plate binding post terminals
for secure connectivity and excellent signal transfer. The binding posts will accept bare wire (up to 10AWG), pin-connectors, and banana
plugs (single only).
Applications: The Dynaudio M20 bookshelf loudspeakers are designed to
offer advanced performance in both stereo and multichannel applications.
- Placement Options: The distance between each
loudspeaker and your listening position should be the same; try to achieve
an isosceles triangle. The distance between the loudspeakers should be the
same or slightly less than the distance between each loudspeakers and your
listening position. The closer the listening position is in relation to the
loudspeakers, the closer the speakers can be positioned to each other. As a
starting point, it is recommended that the speakers be about 6.5' apart from
each other for the best results. To minimize potential influences from the
back and side wall boundaries, it is recommended that the distance from the
speakers to each is at least 1.625', and ideally the distance from each
speaker to the back and side wall should not be equal. Depending on your
personal listening environment and room dimensions, the loudspeakers may be
angled in towards the listening area to focus the sound radiation; this
positioning will typically improve imaging.
- Mounting Options: The Dynaudio M20 bookshelf
loudspeakers are designed to be placed on a speaker stand, shelf, table, or
other piece of furniture with a solid flat-surface. The M20 doesn't provide
a mounting bracket, keyhole slot, or threaded insert to wall-mount the
speaker. However, you can use the PinPoint side-grip wall-mount bracket
(sold separately - see Accessories Tab) to mount the M20 loudspeaker to the
Emit Series: The Emit family of loudspeakers by Dynaudio is
an entry-level series developed and built with the same attention to detail and
passionate craftsmanship as Dynaudio has come to be recognized for around the
world; an entry-level series in high-end audio that truly captures the Dynaudio
experience. The Emit series consists of a Floorstanding loudspeaker (M30),
two bookshelf loudspeakers (M10/M20),
and a center channel loudspeaker (M15).
Dynaudio Fine Tuning: Every Dynaudio speaker model is fine-tuned in
extensive, time-consuming listening tests. Dynaudio even developed its own
amplifier, the Arbiter, solely for this task, to ensure that they are not
restricted by any one manufacturer's design. Extraordinary power reserves, a
frequency bandwidth at the edge of what is technically possible, the exacting
use of absolutely sonically accurate components and circuits, and a unique power
supply that remains completely free from mains noise are just a few qualities of
Dynaudio's ultimate amplifier development. The true sound quality of a
loudspeaker can be judged using this virtually priceless reference amplifier.
After a Dynaudio design has been fine-tuned, it is subjected to the Arbiter.
Only after passing this most difficult test is it ensured that the authentic
sound quality of a Dynaudio loudspeaker can be experienced at home.
