SPA-Pro Series: Professional Sound with Uncompromising Fidelity

The SPA-Pro series delivers enhanced professionalism, purer sound, and higher fidelity, offering a balanced atmosphere for emotional expression. With three models—SPA-Pro, SPA-Pro Ultra, and SPA-Pro MAX—the series caters to different listening needs. SPA-Pro features low impedance and high sensitivity, making it easy to drive while maintaining a pure and immersive sound. The Ultra and MAX versions require higher driving power, offering refined sound quality and greater potential for high-end audio setups.

Advanced Dual Magnetic Tesla Coil with N52 Magnet

SPA-Pro utilizes dual magnetic Tesla coil technology, enhancing analytical precision and dynamic performance beyond conventional drivers. Its N52 high-power magnet, with a magnetic flux exceeding 10,000GS, provides a strong driving force, ensuring a full-bodied and immersive listening experience.

Ultra-Thin Nano Graphene Diaphragm for Precision Sound

SPA-Pro utilizes an ultra-thin, high-rigidity nano graphene diaphragm, engineered for professional-grade acoustic performance. With an elastic modulus of approximately 1TPa, it ensures a smooth, balanced frequency response and delivers highly stable, detailed sound reproduction.

Precision Acoustic Engineering with Flagship Frequency Response

SPA-Pro undergoes hundreds of directional simulation experiments to develop a standardized acoustic cavity structure, optimizing resonance and enhancing musical emotion. Designed with a flagship audio-grade target frequency response curve, it delivers a warm, immersive listening experience with an ultra-wide 5~40,000Hz range, creating an expansive sound field with precise imaging.

Scientific and Artistic Tuning Approach

Utilizing a dual magnetic, dual cavity driver with high performance and efficient driving force, SPA-Pro undergoes fine-tuned adjustments across ten listening aspects, optimizing dozens of acoustic parameters for a precise and refined sound.

Superior Technical Performance for Pure Sound

Total Harmonic Distortion (THD): < 0.5% for a pure and natural tone
Sensitivity: > 109dB/mW for easy driving
Intermodulation Distortion: < 0.05% for a clean and lasting tone
Transient Response Time: < 3ms for fast, clear rhythms
Low-Frequency Rebound: ≈ 40ms for a strong, defined bass response
Signal Attenuation: < 0.5dB for transparent and delicate sound

High-Definition Professional Litz Coaxial Bundled Audio Cable

The SPA-Pro series comes equipped with a high-definition coaxial bundled Litz cable, crafted from oxygen-free copper and silver-plated strands. Its soft, tangle-free design minimizes interference and reduces high-frequency signal loss, ensuring stable, high-resolution audio transmission. With a 0.78mm dual-pin interface and up to 408 finely braided conductor strands, the cable enhances signal integrity for superior sound clarity and detail retrieval.
