The Kunlun Series K12 utilizes British ECATON carbon fiber woven magnetic mid-woofers, delivering outstanding

performance:

Wide Frequency Response Range: Capable of more accurately reproducing musical signals, presenting a more

authentic and natural musical effect.

Low Distortion: Effectively suppresses cone breakup vibration, avoiding distortion caused by unsynchronized

vibration of different parts of the cone due to insufficient rigidity.

High Resolution: Can reveal subtle details in music, such as instrumental harmonics in recordings and the

emotional nuances in a vocalist's voice, enhancing the music appreciation experience.

Fast Transient Response: Responds more quickly to changes in audio signals with almost no delay, better

reproducing micro-details in music.

Excellent Low-Frequency Performance: Provides deep, powerful, and elastic bass effects, strengthening the

rhythm and impact of music, and excels when playing heavy bass music.

The entire Kunlun Series employs a British unwrapped-edge silver rigid cone neodymium pure midrange driver,

delivering exceptional performance:

Rigid Cone Diaphragm: The continuous-profile rigid cone diaphragm offers outstanding rigidity and damping

characteristics. The rigidity effectively reduces distortion caused by deformation, while the excellent damping

properties quickly absorb excess vibrational energy, eliminating resonance and coloration. This results in a pure,

clear, full, rich, and substantial midrange performance.

Super-Strong Neodymium Magnet Circuit:

The neodymium magnet provides a powerful and stable magnetic field for the voice coil, ensuring uniform force

and agile response during vibration. It sensitively detects changes in the audio current signal and swiftly converts

them into diaphragm movement, accurately reproducing the sound signal and greatly enhancing musical

expressiveness.

Unwrapped-Edge Technology:

The unwrapped-edge design of the midrange driver significantly reduces sonic distortion and coloration, making

midrange vocals and instruments sound pure and natural.

The Kunlun Series K12 (Dome Tweeter Version) employs a 1.2-inch metal-coated dome tweeter. With a resonance

frequency above 40kHz, paired with a shallow waveguide dispersion panel and a powerful neodymium magnet

system, the high-frequency extension easily exceeds 30kHz (±3dB). Total harmonic distortion (THD) is less than

0.05% @ 10kHz, offering a sound signature that combines a rich metallic character with natural smoothness.

The Kunlun Series K12 (Diamond Tweeter Version) features a diamond diaphragm tweeter. With its ultra-high

hardness, it performs stable piston motion for sound reproduction even at operating frequencies exceeding 40kHz.

The powerful N45 neodymium magnet circuit provides robust energy support for the high-frequency driver,

enhancing sensitivity and ensuring superior dynamic response in the treble.

Kunlun Series: Acoustic Topology Optimization

Bottom-Ported Low-Frequency Bass Reflex Design

The bass reflex port is concealed at the bottom of the cabinet. Its internal wall curvature is meticulously optimized

using fluid dynamics, and a curved flow guide cone is added at the base to significantly reduce air turbulence noise.

Compared to traditional rear-ported designs, this allows for more flexible and convenient placement, making it

especially suitable for smaller rooms or space-constrained environments.

Acoustically Optimized Cabinet Structure

The cabinet is crafted from 50mm MDF boards, precision-machined with five-axis CNC carving. Internal cross-linked

reinforcement ribs effectively suppress resonance, achieving cabinet coloration distortion of < 0.3% @ 100Hz to

ensure pure sound output. The 5° rear tilt design better adapts to listening environments and, combined with

speaker placement, allows more listeners to experience the ideal "sweet spot."

Independent Enclosures for Mid-High and Low Frequencies

Inside the cabinet, the mid-high frequency drivers are housed in a separate sealed enclosure. This completely

isolates them from the influence of the mid-woofer during operation, reducing standing wave interference and

avoiding intermodulation distortion. As a result, each frequency band performs more accurately, significantly

enhancing the speaker's sense of layering and audio separation.

Adjustable Hidden Casters

The bottom of the speaker is equipped with 4 sets of stainless steel brackets featuring adjustable lift casters,

supporting ±15mm height adjustment. Paired with special anti-slip rubber wheels, they are suitable for various

floor materials such as carpet, tile, and hardwood. This not only facilitates flexible placement but also significantly

enhances cabinet stability, improves low-frequency transmission, and ensures stable sound quality output.

Kunlun · Zero-Coloration Crossover Technology

Fourth-Order Crossover Circuit

Utilizing a Hi-End grade fourth-order crossover circuit, it features high-efficiency attenuation slopes, thoroughly

separating different frequency bands for superior sound layering. The symmetric phase design (Linkwitz-Riley) of

the four-stage circuit ensures strict amplitude and phase symmetry at the crossover points, with uniform group

delay. This achieves "seamless integration" of audio signals and significantly enhances phase fidelity.

Bi-Wiring Design

The bi-wiring technology is employed, where mid-high frequency and low-frequency signals are  transmitted

through separate audio cables. This physically isolates electrical interference, preventing low-frequency currents

from modulating weak high-frequency signals. It reduces mutual coupling of internal crossover  components,

eliminates magnetic and electric field interference between the low-frequency inductors and  high-frequency

capacitors within the crossover, improves signal separation, lowers intermodulation distortion,  ensures pure signal

transmission, and comprehensively enhances sound purity, separation, and dynamic performance.

Mortise and Tenon Cabinet Structure

Utilizing a unique interlocking design of protrusions and recesses, the mortise and tenon structure tightly joins the

various components of the cabinet to form a solid, unified whole. This enhances the stability of the acoustic

structure, effectively controls resonance, and improves sound clarity and layering. Particularly during the playback

of high-dynamic music, it strengthens the depth and impact of the bass.
