In the contemporary landscape of high-performance sound reinforcement, the demand for low-frequency extension and precision has reached unprecedented levels. The Ks28 Low-Frequency standard represents the pinnacle of dual 18-inch subwoofer engineering, designed to meet the rigorous demands of global touring, large-scale stadium installations, and high-SPL industrial soundscapes.
As a leading OEM Ks28 factory and exporter, we recognize that "bass" is no longer just about volume; it is about thermal management, laminar airflow, and phase coherence. Our research and development focuses on the "Information Gain" of acoustic physics—how to minimize port turbulence while maximizing the physical impact of the 25Hz - 100Hz frequency spectrum.
Modern pro-audio ecosystems require a holistic approach to sound distribution. Our Ks28 solutions are not merely stand-alone units; they are part of a macro-economic shift towards integrated "Smart Sound" environments. From Industrial Noise Cancellation modules to Public Infrastructure Safety PA Systems, the application of low-frequency technology is expanding.
Providing the backbone for Olympic-sized stadiums and international music festivals where 143dB peak SPL is a mandatory requirement for audience engagement.
Utilizing high-power sub-bass for acoustic testing and resonance analysis in aerospace and automotive manufacturing plants.
High-clarity vocal reinforcement systems combined with sub-bass for large-scale outdoor public addresses and emergency broadcasting.

Navigating international audio markets requires more than just high-quality products; it requires Regulatory Authority and Operational Expertise. As a global exporter, TACT Pro Audio ensures all Ks28 series and line array components adhere to international safety standards, including CE, RoHS, and local fire-safety certifications for fixed installations.
We provide localized support through:
Established in 2010, TACT Pro Audio was established by founder Mr. Qiu and Mr. Li, who have been engineers in the professional audio industry since 1999. With over 20 years of collective experience, the leadership continues to drive research and technological developments in high-end acoustic systems.
Our 18,000 square meter facility houses specialized workshops for cabinet production, polishing, painting, and rigorous assembly/testing. We don't just build speakers; we build acoustic instruments designed for the future.

Professional Vision for 2025
The future of low-frequency audio lies in Adaptive Control and Sustainable Materials. TACT Pro Audio is currently investing in AI-driven DSP algorithms that predict thermal compression before it occurs, allowing for "safer" high-output performances. We are also exploring eco-friendly composite resins for cabinets that maintain the acoustic properties of birch while reducing environmental impact.
By 2026, our goal is to integrate Dante-native networking into every active Ks28 module, providing a seamless "Plug-and-Play" experience for the world's most complex audio networks.
Our cabinets use genuine 18-layer Russian Birch plywood with a CNC-milled internal bracing system. Unlike cheaper MDF alternatives, our design prevents energy loss through cabinet vibration, ensuring all power is directed into sound pressure.
Yes. We provide full ODM services including custom grill designs, logo laser-etching, and bespoke DSP tuning to match your specific market requirements.
Every unit is vacuum-sealed and protected by a 5-layer corrugated carton with internal foam-mold support. For sea freight, we apply anti-moisture silica treatments to ensure the wood and electronics arrive in perfect condition.
Absolutely. Our Ks28 series is designed with standard rigging and preset support for both forward-facing and cardioid arrangements to maximize rear-rejection.
