The Kunlun Series K10 utilizes British ECATON graphene mid-woofers, offering distinct acoustic technical advantages:
High Sensitivity & Fast Response: Graphene exhibits minimal deformation and inertia during vibration, enabling instantaneous response to audio signal changes. This results in superior transient response, achieving precise sound reproduction where even the subtlest musical dynamics are clearly presented.
Wide Frequency Response: The graphene diaphragm covers a full frequency range from ultra-low to high frequencies. It delivers deep and rich bass in the low-frequency range, enhancing musical rhythm and impact. In the midrange, it clearly reproduces rich sonic details, significantly improving overall sound layering and clarity.
High-Fidelity Audio Reproduction: The graphene diaphragm accurately follows audio signal vibrations, faithfully reproducing everything from delicate musical nuances to powerful dynamic effects.
Bass & Dynamic Response: In the low-frequency range, graphene provides strong and elastic vibration, producing deep and full-bodied bass that perfectly reproduces sub-30Hz sounds like drumbeats. Its outstanding dynamic response capability brings music to life with vivid expressiveness and captivating impact.

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 K10 (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 K10 (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.

This achieves "seamless integration" of audio signals and significantly enhances phase fidelity.
Bi-Wiring Design
The bi-wiring (bi-wring) 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.
