COSVOX Debuts Eclipse Series at Canton Fair Audio Expo, Redefining Premium Sound Standards
May 22, 2024, Guangzhou — At the recently concluded 2024 Guangzhou International Audio & Record Exhibition, emerging high-end audio brand COSVOX made a grand appearance with its flagship modular system, Line + SUB 212. With its exceptional sound quality and innovative design philosophy, COSVOX became a standout highlight of the event, attracting significant attention and acclaim from seasoned audiophiles and industry professionals alike. The system’s core lies in its modular concept and unique hybrid technical architecture, aiming to deliver users unprecedented flexibility and reference-level sound quality experiences.
Modular Design: Defining Flexible Hi-End Experiences
The centerpiece of COSVOX Audio’s exhibition was the Line bookshelf speaker and SUB 212 subwoofer, showcasing the brand’s dual pursuit of sound quality and practicality. The modular design allows users to freely configure the system according to their needs—from two-channel Hi-Fi setups to multi-channel home theater systems, and even scalable large-scale line array configurations, catering to diverse scenarios ranging from home listening to professional monitoring. For example, a basic configuration could include one Line speaker and one SUB 212 subwoofer per channel, while stacking four Line speakers and two SUB 212 subwoofers can create a large line array. Alternatively, integrating a Line Center speaker enables an immersive home theater experience, covering everything from personal listening to professional studio requirements.
To simplify operation for enthusiasts, both the Line and SUB 212 feature professional-grade balanced inputs and outputs, along with dedicated COSVOX Link interfaces, ensuring low-noise and stable signal transmission. When used together, the Line speaker and SUB 212 subwoofer require only a single power cable connected to the SUB 212, which then powers the Line speaker via a proprietary link cable, significantly reducing wiring complexity. Additionally, both modules support independent level adjustments, with the Line speaker equipped with a high-frequency gain control knob (±3dB adjustable). Users can fine-tune the sound in real-time based on room acoustics or music genre (e.g., delicate highs for classical or powerful lows for electronic music), achieving a personalized "sound-for-everyone" experience.
Aesthetically, the Eclipse Series features sealed enclosures CNC-machined from 6061 aerospace-grade aluminum. A single Line speaker weighs 51 kg, while the SUB 212 tips the scales at 105 kg, leveraging mass to suppress resonance. Combined with the brand’s proprietary CarbonEcho composite diaphragm drivers and Purifi Audio ultra-low-distortion amplifiers, this forms a solid acoustic foundation.
Technological Breakthrough: The Perfect Balance of Analog and Digital
On the technical front, the Line bookshelf speaker adopts a "compact line array" design, with six 4-inch AMT tweeters arranged linearly and recessed for phase alignment, paired with a 6.5-inch mid-woofer featuring a two-layer dry carbon fiber composite diaphragm. Measured frequency response extends down to 55Hz. The SUB 212, equipped with dual 12-inch push-pull woofers (seven-layer composite diaphragm) and a 1000W Hypex DSP amplifier, achieves a Linkwitz-Riley crossover filter with a -24dB/Oct slope, maintaining flat phase response across the full 20Hz-20kHz range. The innovative "analog active crossover + DSP bass management" hybrid architecture preserves the "analog warmth" of instrumental textures (e.g., the lifelike imaging on *Great Audiophile Classics*) while leveraging DSP to optimize low-frequency dynamics (e.g., the punchy drum beats on *Ten Years of Excellence*). The system supports switching between full analog and full DSP modes, catering to both audiophiles and professional engineers.
On-site attendees and industry insiders praised COSVOX Audio’s performance. A veteran audiophile remarked, "The Line speaker’s reproduction of cello is among the most realistic I’ve ever heard," while a professional audio engineer lauded its "analog active crossover + DSP bass management" hybrid architecture for balancing "sonic purity" and "parametric precision" in monitoring scenarios by preserving analog signal paths for highs while digitally optimizing lows.
During live listening tests, the Line speaker demonstrated monitor-grade resolution, rendering *Bach’s Unaccompanied Cello Suites* with pristine clarity. The Line + SUB 212 combination, powered by a Purifi 1ET7040SA amplifier and Hypex 3000W power supply, reproduced the full-bodied lows and expansive soundstage of the direct-cut vinyl album *Discover Again*, with low-frequency tonal details rendered distinctly after DSP correction.
The founder of COSVOX stated that the Eclipse Series breaks the boundaries of traditional Hi-End audio through aerospace-grade craftsmanship, modular architecture, and full-chain innovations in acoustic technology. Future plans include introducing surround speakers to complete multi-channel setups, continuing the pursuit of sonic perfection.
