Dynaudio Excite X38
Floor-standing speaker (Walnut Satin)
Our take on the Dynaudio Excite X38 by Crutchfield's Steve Kindig
Feel connected to your music and movies
There are three floor-standing speakers in Dynaudio's Excite series, and in many ways the Excite X38 is the Goldilocks model. Its larger woofers deliver more low-frequency power and impact than the smaller X34, and it costs significantly less than the larger X44. At just 40" tall, the X38 is pretty compact, yet it sounds startlingly big whether you're doing some focused listening to your favorite tunes, or just kicking back with a movie.
When Dynaudio visited Crutchfield for training, they set up several pairs of their speakers, including the Excite X38, and played the same music clips through each pair so we could compare. They all produced the precise detail and huge soundstage that are Dynaudio hallmarks. The speakers made even audio demo standbys like Steely Dan's "Babylon Sisters" and Lyle Lovett's "Church" sound fresh. The X38s weren't the priciest speakers in the group, but when I asked around, most of our folks liked them best.
An expanded sweet spot
You don't have to be sitting in the "sweet spot" to enjoy the X38's expressive performance. Dynaudio borrowed some of the controlled dispersion technology found in the company's pro studio monitors and flagship home speakers.
By fine-tuning the alignment of the drivers on the front baffle, as well as the crossover design, Dynaudio eliminated some of the sound colorations caused by reflections off the floor and ceiling. This focuses more sound on listeners, even improving off-axis response for those sitting off to the sides.
Dynaudio woofers dig deep
All Dynaudio woofers use the company's ultra-rigid, ultra-lightweight Magnesium Silicate Polymer (MSP) cone material, enabling the woofer to stop and start on a dime. An MSP cone is molded in one geometrically perfect piece, which helps to optimize sound dispersion. It also eliminates the need for a separate dust cap, further enhancing the cone's structural integrity.
This full-range 3-way design starts at the top with a 1-1/8" dome tweeter, and right below it is a 5-1/2" MSP midrange. The dual 7" MSP woofers have extraordinarily large 3" voice coils, which help the Excite X38 achieve its nimble, tuneful bass response. Dynaudio relies on high-quality 1st-order filters (6 dB/octave) in their crossovers. This type of filter is known for its excellent transient response, but 1st-order filters demand the finest drivers, with wide frequency response — like Dynaudio's.
A tweeter that sings
When Dynaudio's engineers find something that works, they stick with it. Core designs like Dynaudio's renowned soft-dome tweeters, have been steadily improved and refined over the course of 40 years. The Excite X38's tweeter features a silk dome with a special coating that improves dispersion while eliminating high-frequency breakup. It sounds effortlessly detailed, neutral, and non-fatiguing, even when you crank up the volume.
Both tweeter and woofer use aluminum-wired voice coils that are lighter than traditional copper coils. That means Dynaudio can make larger voice-coils for a given weight. Larger coils exert better control over the dome or cone's movement, which lowers distortion.
Great for music and movies
Dynaudio's expressive, transparent sound suits every kind of music, soft or loud, acoustic or electric. And the qualities that make these speakers so enjoyable for music listening also make for immersive home theater. They can reproduce extreme dynamic range, and dig deeper into the bass than most similarly sized speakers.
The Excite series is one of Dynaudio's lowest-priced speaker lines, but it was developed using the same exhaustive measurements and listening tests the company relies on to develop its price-no-object designs.
The X38's cabinet is ported in the rear to provide a bit of extra low-frequency oomph. A foam plug is included which you can insert in the port to tighten bass response when placing the speaker near a wall. Also, positioning the X38 at least a couple of feet out from any wall will improve the soundstage.
Four stabilizer feet are included, with rubber pads for hard floor surfaces and spikes for carpet. Dynaudio feels that the speaker should not be used without the outrigger feet installed.
With its 4-ohm impedance, the Excite X38 should be driven with high-current, high-quality amplification.

3-Way Floorstanding Loudspeaker: Dynaudio's Excite X38 Floorstanding speaker utilizes a 3-way driver design featuring a 1.1" precision-coated silk soft-dome tweeter, one 5.5" magnesium silicate polymer (MSP) midrange driver, and two 7" magnesium silicate polymer (MSP) woofers with 3" voice coils. The result is true high-end sound with great dynamic range, expansive soundstage, articulate bass, detailed midrange, and a natural tonal balance. The minimal distance between the tweeter, midrange, and woofers serves to improve timing and phase.
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 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) Woofers & Midrange: 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 dispersion.
- 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/2nd 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/2nd order filter (6/12 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 X38 cabinet also features a magnetically-attached, acoustically-optimized front grille.
Bass Reflex Port w/ Foam Port Plug: The Excite Floorstanding 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 X38 Floorstanding 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 X38 Floorstanding loudspeaker is 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 Excite X38 Floorstanding
loudspeaker comes with outrigger feet which will need to be installed to the
bottom of the cabinet. The outrigger feet feature four resonance-absorbing
rubber pads for hardwood and tile flooring, while
four adjustable spikes can be used on carpeted flooring. Both the rubber
pads and spikes are integrated into the outrigger feet. The spikes simply
screw in and out.
- Dimensions with Rubber Feet: 10.5" (w) x 41.375" (h) x 12.375" (d)
- Dimensions with Spike Feet: 10.5" (w) x 41.75" (h) x 12.375" (d)
Note: The Dynaudio Excite X38 Floorstanding loudspeaker should not be used without the outrigger feet installed.
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.
