Suitable for 4–11 loudspeakers rated under 150 W Key benefits Reliable compatibility: Designed specifically for loudspeakers in the 4–11 size range with power ratings below 150 W, making installation and replacement straightforward. Better thermal management: Hollow-core inductor with high heat dissipation reduces thermal buildup, helping components run cooler and maintain consistent performance. Improved audio quality: Special sound capacitor for imported audio reduces signal loss and supports clearer, more accurate sound reproduction. Protects your system: Built-in overcurrent protection device prevents damage from excessive current, increasing safety and protecting connected components. Long service life: Durable construction and protective features extend component lifespan and reduce the need for frequent replacements. Features and specifications (as provided) Compatibility: Suitable for 4–11 loudspeakers under 150 W Inductor: Hollow-core inductor with high heat dissipation Capacitor: Special capacitor for imported audio (sound capacitor) Protection: Uses an overcurrent protection device; durable with long lifespan How this product solves common problems Prevents overheating and component failure by using a hollow-core inductor that dissipates heat more effectively than standard inductors. Improves clarity and reduces distortion with a dedicated sound capacitor optimized for imported audio components. Guards against catastrophic failures and costly repairs with built-in overcurrent protection. Typical use scenarios Repair or upgrade of passive crossovers in home loudspeakers rated under 150 W to improve thermal stability and audio clarity. Building or refurbishing custom speaker cabinets that require reliable inductors and capacitors matched to 4–11 drivers. Replacing failed crossover components in imported audio systems to restore original sound quality and add overcurrent protection for longer-term reliability. Practical notes for buyers Confirm your speaker size and power rating fall within the specified range (4–11; under 150 W) before purchasing. Compatible as a component for passive crossover networks; installation should follow proper wiring and safety procedures. The combination of a hollow-core inductor, sound capacitor, and overcurrent protection is intended to deliver stable performance and extended component life without altering original system design.
