25 – 225 watts suggested amplifier power range
25 – 225瓦建議擴大機功率範圍
JBL engineers designed the GTO 509C midrange speaker to produce strong, clear sound from a head-unit or amplifier capable of delivering up to 225 watts of power. This makes the GTO 509C an ideal match to systems powered with head-unit or factory-amplifier power levels. Even better, the speaker matches many of the GTO Series’ amplifier combinations. As a result, it can keep up with systems that feature one or more subwoofers and satisfy high-fidelity audiophile listeners. And its great power-handling specifications also increase reliability over the lifetime of the speaker.
JBL 工程師設計的 GTO 509C 組合揚聲器可透過頭戴裝置或擴大機 （功率最高可達 225 瓦） 釋放有力、清晰的聲音。這種結構使 GTO 509C 非常適合透過頭戴設備或出廠擴大機功率供電的系統。更值得一提的是，這款揚聲器還可搭配多種 GTO 系列的擴大機組合。因此，它可支援配備一個或多個低音揚聲器的系統，並滿足高保真發燒友的需求。其強大的功率處理規格還可提高揚聲器壽命內的可靠性。
