Two-Way Bookshelf Loudspeaker: Dynaudio's Excite X14 bookshelf speaker
features a 1.1" precision-coated silk soft-dome tweeter and one 5.5" magnesium silicate polymer (MSP) mid-woofer for true high-end sound with great dynamic
range, expansive soundstage, exceptional accuracy, and a natural tonal balance.
The minimal distance between tweeter and mid-woofer serves to improve timing and
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
- Damping Chamber: The tweeter
also 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, 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
- Aluminum Voice Coils: 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 accuracy.
- 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.
Furniture Grade Cabinets: Dynaudio's high-quality, furniture-grade cabinets
are painstakingly assembled and finished by experts in Skanderborg Denmark to
make sure the enclosure perfectly matches the custom drivers. The Danish
tradition of craftsmanship drives the meticulous process of selecting and
matching veneers from the finest woods available, followed by careful sanding,
polishing and coating. 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 resonance. The Excite X14 cabinet
also features a magnetically-attached, acoustically-optimized front grille.
Bass Reflex Port w/ Foam Port Plug: The Excite bookshelf
speaker features a bass reflex enclosure with a rear-firing port for greater efficiency
and bigger bass response. 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 Excite X14
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 Excite X14 bookshelf loudspeakers
are designed to offer advanced performance in both stereo and multichannel
- 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 X14 bookshelf
loudspeakers are designed to be placed on a speaker stand, shelf, table, or
other piece of furniture with a solid flat-surface. The X14 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 X14 loudspeaker to the
Excite Series: The Excite family of loudspeakers by Dynaudio
combines high-end sound quality with an elegant, slim-line design. The Excite series
consists of Floorstanding loudspeakers (X34/X38/X44),
bookshelf loudspeakers (X14/X18),
and center channel loudspeakers (X24/X28).
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.
