Speaker Crossover 200W 3Way Woofer Frequency Divider with Noise Reduction and Adjustable Cutoff Control for 4 Inch Above Speakers

Frequency Dividers Speaker Active Component (Model: Frequency Dividers) Material: Aluminum Color: B for 4 inch and above Package: 1 x Frequency Dividers Product highlights Purpose built speaker active component designed as a speaker frequency divider and hifi crossover filter module. Suited for woofer crossover duties in speaker systems with drivers 4 inch and larger. Solid aluminum construction for durability and stable thermal behavior. Built in operational amplifier for accurate filtering and low distortion. Cutoff frequency and filter slope can be adjusted using external resistors or software for flexible tuning. Designed to clean power and signal paths: removes frequency noise from AC derived power, supplies more stable and purer DC to sensitive circuits, and reduces system instability caused by power noise. Effective electromagnetic interference suppression. Reduces EMI produced during equipment operation and resists intrusion from external electromagnetic fields, helping systems operate reliably in multi device environments. Optimized for audio frequency bands and capable of extracting target audio ranges such as 300 Hz to 3.4 kHz, making it useful for voice communication and microphone applications where clarity and noise reduction are important. Key benefits Improved audio clarity: precise band selection enhances vocal intelligibility and reduces environmental noise in voice and mic applications. Greater system stability: power noise filtering supplies steadier DC to sensitive electronics, reducing artifacts and interference in audio processing chains. Enhanced electromagnetic compatibility: EMI suppression helps prevent cross talk and interference when multiple devices are operating nearby. Flexible integration: adjustable cutoff and slope let you tailor the filter to specific drivers or application requirements without replacing hardware. Technical and compatibility notes Item type: Speaker Active Components Model number: Frequency Dividers Material: aluminum Color designation B recommended for speaker drivers 4 inch and above Built in operational amplifier; external components or software required to set precise cutoff frequency and slope Practical applications 1) Woofer crossover in home or studio speaker systems: use as a hifi crossover filter module to route low frequencies to woofers while blocking higher bands for cleaner output. 2) Voice and microphone systems: extract the voice band range such as 300 Hz to 3.4 kHz to improve clarity for communication devices, paging systems, or conferencing setups. 3) Instrumentation and teaching labs: use in audio processing experiments, filter design exercises, and prototyping where adjustable cutoff and slope are needed for demonstration or measurement. What this product solves Reduces frequency power noise that can degrade audio and electronic performance. Suppresses EMI that can cause interference between components and devices. Provides a configurable filtering stage for tailored audio band selection and improved signal integrity.
