JBL 15" WPU1509 - 450 Watts RMS - 8 Ohm Woofer

Professional 15 "woofer designed to meet the requirements of high-power bass reproduction systems with the use of low-volume sound-absorbers. For a high degree of performance and reliability, each component uses the most advanced technology available.
The 4 "(100 mm) mobile coil uses high temperature resistant wire and polyimide formwork.
The cone is made of long fiber cellulose and impregnated with special resins that guarantee the mechanical assembly great mechanical stability and perfect bass reproduction.
The new fabric suspension receives a special rubber-based treatment reducing distortion and fatigue; the spider is double to ensure perfect centering of the moving assembly.
The injected aluminum speaker housing has high structural rigidity and aids in heat dissipation.
The highly optimized finite element magnetic set was developed in order to minimize harmonic distortion, thus having a symmetrical magnetic field and extended pole. The thermal dissipation is guaranteed by a large central ventilation hole and by 6 lathe windows positioned in the housing, providing great dissipation of the heat coming from the coil, guaranteeing maximum efficiency and low power compression
