01 Coaxial–Common Magnetic–Common Vibration–Wideband Technology

The Celestial Series embodies the essence of European and American electroacoustic design. The coaxial driver adopts a coaxial common-magnetic technology, where the acoustic centers of the high, mid, and low frequencies lie on the same axis within the same magnetic system, truly achieving “coaxial, common-magnetic, common vibration, wideband.†With the support of a neodymium magnet system, the tweeter delivers high sensitivity and a wide frequency response, ensuring purity and clarity across all three frequency bands.

02 High Phase Fidelity and Accurate Soundstage Imaging

The coaxial common-magnetic driver aligns the acoustic centers of the high, mid, and low frequencies on the same axis and at the same point. This allows all frequency bands of the music signal to propagate toward the listener along the same axis with minimal phase deviation, achieving high fidelity. Additionally, sound positioning becomes more precise, enhancing the separation of various instrument sounds. Listeners can clearly distinguish the location of each sound and instrument, resulting in a more authentic auditory experience.

03 Even Sound Energy Distribution Across Space

The Celestial Series utilizes a magnetic shielding system in its speakers, enabling a more uniform propagation of sound waves. This allows for an ideal frequency and energy distribution across a wider area, maintaining excellent soundstage performance in various environments. It ensures that listeners in different positions within the listening room can enjoy clear and balanced sound.

04 Natural, Warm, and Smooth Tonality with Refined Texture

The Celestial Coaxial Speakers deliver a sound reproduction that closely approximates a point source, resulting in a more natural and fluid audio presentation. As the fundamental tones and harmonics are generated and overlap on the same axis and at the same point, the clarity and refined texture of the sound are significantly enhanced, while the overall tonality remains warm and inviting.

05 Excellent High-Frequency Extension and Outstanding Mid-Low Frequency Performance

The Celestial Series employs a German-made aluminum-magnesium-titanium alloy diaphragm for its tweeter, combined with a gold-plated waveguide horn, enabling high frequencies to extend up to 26 kHz for an exceptionally smooth treble response. The low frequency reaches down to 26 Hz, ensuring powerful bass performance and impactful dynamics. Midrange and vocal reproduction are delivered with rich expressiveness, conveying a warm and refined sonic character.

06 Adjustable Crossover System Design

Utilizing an adjustable crossover technology with “high-frequency gain and low-frequency presence†controls, supporting bi-wiring connections, the system allows five-level adjustment for both treble gain and bass presence. Listeners can fine-tune the sound based on personal preference, music genre, and acoustic environment to achieve their ideal audio experience.

07 Curved Cabinet Designed with Acoustic Principles

The Celestial Series features a system design that is simple, elegant, and refined, allowing it to blend seamlessly with various interior styles and enhance overall aesthetic appeal. The cabinet design also adheres to acoustic theory, with its curved structure improving internal sound wave reflection and elevating the acoustic performance of the enclosure.

08 Wide Application Environment Adapts to Different Music Genres

Whether in a home Hi-Fi system, music hall, home theater, or professional monitoring setup, the Celestial Coaxial Speakers stand out with their superior acoustic performance and sound quality. They are adept at handling a diverse range of music genres, including vocals, orchestral music, classical compositions, and symphonic works.

Mid-Bass Driver (Mid-Bass Speaker)

Featuring a British-made composite wool fiber cone, Japanese cloth surround, and American DuPont Conex spider, it carries on the century-old coaxial legacy while significantly enhancing midrange vocal performance.

Tweeter

The driver features a German-made aluminum‑magnesium‑titanium alloy diaphragm paired with a gold‑plated waveguide horn, extending high‑frequency response up to 29â€Â¯kHz for airy, smooth, and richly detailed treble. With a high‑flux 15,000‑Gauss neodymium common‑magnetic structure, it enables the mid‑bass and tweeter to operate within the same magnetic circuit, achieving true “coaxial‑common‑magnetic‑common‑frequency‑common‑vibration†performance. This design also ensures extremely high conductivity and outstanding interference immunity.

Adjustable Crossover Design

The crossover system of the Celestial Series is meticulously calibrated and supports bi‑wiring. Both high‑frequency gain and low‑frequency presence offer five adjustable levels each, allowing up to 25 sound‑profile combinations. Enthusiasts can easily tailor the system’s performance according to personal preference, music genre, and room acoustics—enhancing the system’s versatility while adhering to the audiophile principle that “the best sound is the one that suits you best.â€

With both adjustment pins set to the middle position, the system delivers the standard factory‑calibrated sound.
