Premium OEM audio systems utilizing robust transducer engineering and architectural enclosures built to exact target acoustics.
In the competitive vertical of professional sound reinforcement, the Ba118s Ferrite Driver serves as a benchmark component. Known for its rugged structural resilience and optimal thermal behavior, it forms the powerhouse of major club and outdoor touring subwoofers. In modern audio engineering, ferrite motors are often preferred over neodymium alternatives when mechanical momentum, flux density consistency under elevated temperatures, and budget-efficiency are paramount.
The Ba118s driver features a highly optimized magnetic circuit design, designed to prevent flux saturation under extreme currents. Utilizing premium-grade Y30 or Y35 ceramic strontium ferrite magnets, this driver maintains a high magnetic flux density throughout continuous operation. This ensures consistent low-frequency reproduction with minimum harmonic distortion even during long-term high-power peak surges.
TACT Pro Audio: Over 10+ Years of Precision Engineering Production Experience
A closer look at how modern simulation and material sciences elevate our OEM Ba118s Ferrite Drivers.
Using Finite Element Analysis (FEA), our engineering team models the displacement of the magnetic flux within the voice coil gap. This guarantees high linearity of the BL force factor, reducing intermodulation and second-harmonic distortion. It prevents off-center mechanical biases during high excursion, keeping the cone displacement completely uniform.
Equipped with a high-temperature 4-inch (100mm) copper voice coil wound on a durable fiberglass/Kapton former. By utilizing inside/outside winding technology, we double the surface area exposed to cooling air currents, increasing the thermal power handling capacity and minimizing power compression under high electrical loads.
Outdoor operations require component protection. The cellulose paper cone is coated with a hydrophobic protective layer on both sides, defending the speaker against humidity, condensation, and rain spray. The surround consists of a heavy-duty triple-roll polycotton structure that prevents fatigue during deep excursions.
Established in 2010, TACT Pro Audio (TACA Pro Audio) was founded by industry pioneers Mr. Qiu and Mr. Li, who have served as leading acoustic and mechanical engineers in the professional audio sector since 1999. Today, with over 24 years of cumulative design experience, Mr. Qiu and Mr. Li continue to direct the R&D division, pushing boundaries in transducer efficiency, system integration, and DSP processing.
Our manufacturing complex spans more than 18,000 square meters. Unlike assembly-only suppliers, we maintain a vertically integrated production line. This includes our proprietary cabinet woodwork workshop, precision polishing lines, electrostatic painting lines, dynamic transducer assembly lines, and a state-of-the-art testing facility. This control allows us to deliver high acoustic precision across all configurations.
How our localization in Panyu, Guangzhou (China's pro-audio hub) optimizes manufacturing for worldwide buyers.
Operating in the heart of China’s pro-audio manufacturing hub allows TACT to source high-grade raw materials (such as raw steel, custom voice coils, special structural adhesives, and CNC birch plywood) at short notice and with minimal transport overheads. This cluster effect results in faster prototyping and highly competitive pricing structure.
We work closely with global system designers. If you require custom Thiele-Small parameters for a specific box volume, our acoustic engineers can modify the voice coil winding depth, change the spider compliance, or alter the cone mass to yield the exact frequency response, resonant frequency (Fs), and Q-factor profile your project demands.
Every driver produced in our factory goes through a rigorous quality control check. Utilizing Clio and Klippel testing suites, we run a full sweep analysis measuring impedance curves, harmonic distortions, voice coil alignment, and frequency responses. Drivers that do not match the ±1.5 dB tolerance standard are immediately rejected.
Beyond supplying raw Ba118s Ferrite Drivers, we construct full cabinetry, matching the driver with the correct internal volumes, port structures, and crossover tuning. We advise and configure sound systems based on the physical size of the installation site, specific outdoor layouts, SPL goals, and budget constraints.
Meeting global standards of electrical safety, environmental protection, and architectural rigidity.
Our operational framework matches CE certifications, RoHS directives, and international safety protocols. The cabinet works, raw materials, and electronics used within our active line array models undergo continuous monitoring to ensure they adhere to strict fire-retardant standards (UL94) and structural load-bearing limits. When importing speakers or drivers from TACT Pro Audio, you are getting certified reliability, guaranteeing easy customs clearance and adherence to regional building regulations.
We provide speakers with OEM & ODM services that include comprehensive speaker design, voice coil and magnet structure adjustment, box styling, and meticulous QC analysis before shipment. Additionally, we provide custom project solutions tailored to different occasions, project types, target audiences, and budget margins.
Our engineering work is respected in over 50 countries. Every system features custom design patents and CE certifications, allowing our clients to distribute locally with total confidence. Our goal is to supply high-end, reliable components that improve sonic quality and performance.
Become the most valuable and service-oriented professional audio manufacturer and supplier in China. With this vision, our company continuously strives to stay at the forefront of the rapidly changing audio industry and keep up with modern market trends.
By incorporating smart amplifiers, custom-engineered ferrite materials, and advanced DSP modules, TACT Pro Audio aims to remain a vital partner for global distributors, venue installers, and stage-rental companies.
Explore the physical scenarios where the Ba118s Ferrite Driver and our matched cabinets perform best.
Outdoor acoustic environments present challenges like wind dispersion and long-distance decay. Using dual 10-inch or double 15-inch configurations matching the Ba118s, our line array systems deliver high acoustic throw and narrow vertical dispersion, ensuring clear, far-reaching sound coverage for thousands of spectators.
Relatively large halls with high ceilings are prone to acoustic resonance issues. By utilizing a balanced single or dual subwoofer loaded with the Ba118s driver, installers can control low-frequency directionality, maintaining clean and intelligible vocals and organ responses while preventing low-end rumble from washing out the midrange.
Club operations require speakers to run continuously for up to 8 to 12 hours. The Ba118s Ferrite Driver is built to handle this type of load. Thanks to its double spider construction and efficient heat-dissipation ports, it delivers clean, heavy bass all night without experiencing thermal shutdown or compliance fatigue.
As digital amplification and class-D high-efficiency modules continue to dominate the amplifier market, the demands placed on transducer components have grown. A modern transducer must handle high peak voltages without bottoming out.
At TACT Pro Audio, Mr. Qiu and Mr. Li have aligned our factory's capabilities with these industry changes. Our latest cabinets combine high-excursion ferrite drivers with active, DSP-controlled amplifiers. This pairing ensures that every unit is optimized for protection, frequency equalization, and delay alignment, resulting in a cohesive plug-and-play solution.
