CarbonEcho Loudspeakers

The Cosvox team has independently developed the X7 (mid-bass), F7 (passive radiator), X12 (bass), and X18 driver units, pursuing ultimate performance and system compatibility. These units feature a sandwich-composite diaphragm structure composed of two layers of dry carbon fiber and one layer of high-molecular damping material. Leveraging the high rigidity and lightweight properties of carbon fiber, combined with a ferrite-neodymium hybrid motor system and multiple pure copper shorting rings, the CarbonEcho loudspeakers break through traditional limitations. They deliver a wide frequency response, deep bass, crystal-clear highs, structural stability with anti-vibration properties, precise motion control, and lifelike sound with low distortion—immersing listeners in a pure ocean of music. The damping layer plays a critical role, providing excellent damping strength to the diaphragm and optimizing harmonics to favor even-order harmonics, resulting in a warm, rich tonality that replicates the experience of a live performance.

AMT Line Array

Cosvox boldly innovates by applying line-array technology to high-frequency units, creating the AMT Line Array. Composed of multiple self-developed AMT (Air Motion Transformer) tweeters in a compact line-array configuration, it achieves a total radiating area of 24 square inches, proportionally increasing sound pressure. Under one-meter listening conditions, it reaches a maximum SPL of 115dB with THD < 0.5%, extends highs up to 40kHz, and exhibits near-zero compression within its effective range—delivering extraordinary sonic performance.

Super ClassA+D
Amplification Technology

The "Eclipse" system adopts revolutionary hybrid amplification: a 91dB CMRR fully balanced input stage ensures ultra-pure signal transmission with -120dB THD+N, while the Class A preamp preserves musical nuance, and the Class D power stage delivers robust drive. Coupled with 5-step gain adjustment and continuous high-frequency compensation, it perfectly adapts to various audio sources and listening environments.

Physical Phase Alignment

Cosvox’s Physical Phase Alignment technology spatially arranges drivers with varying parameters through calculated positioning, achieving perfect phase alignment in the listening area. This dramatically reduces the number of passive crossover components and power loss, achieving near-direct-drive signal transmission and efficiency.

AlumToneXperience Technology

Cosvox enclosures are entirely CNC-machined from 6061 aerospace-grade aluminum, with precisely calculated curvilinear joints. Beyond their elegant and rigid exterior, they reduce diffraction effects to near-zero, allowing unimpeded soundwave propagation that reproduces the recording’s spatial acoustics while eliminating "box resonance." The ultra-rigid construction not only handles greater bass energy and deeper extension but also better protects drivers under extreme SPL conditions.

Linkwitz-Riley Crossover Technology

A 4th-order Linkwitz-Riley filter design ensures 24dB/octave precision in frequency division. This technology not only enables rapid band attenuation but also maintains phase coherence across the entire spectrum, eliminating phase distortion from traditional passive crossovers and setting a textbook benchmark for low-frequency reproduction.

Redefining Sonic Purity Through Material Science

In pursuit of the ultimate listening experience, Cosvox spares no detail. The "Eclipse" system’s crossover components—capacitors, resistors—are sourced from world-renowned brands, with inductors hand-wound from 6N high-purity copper foil at significant cost. Interconnecting modules, 7N monocrystalline copper and 6N monocrystalline silver cabling ensure pristine signal transmission.
