JBL GC12 是一款全频高质量点声源扬声器，专为酒吧、俱乐部等娱乐场所以及音乐餐厅的现场扩音而设计。
JBL GC12 采用 1.5" 专利 D2 双振膜双音圈压缩驱动器，即使在高音量或细微聆听级别下，也能确保平顺而延伸的高频响应，超低失真。配备 12" 低频驱动器，JBL GC12 可重现更宽广的频率范围，频率响应曲线更加平坦，失真率更低。全新设计的分频网络进一步增强了声学性能，确保低频和高频驱动器之间的无缝衔接，实现清晰、饱满和高保真的音乐重现。
JBL GC12 采用耐用的桦木胶合板构造，有效消除箱体谐振并改善低频响应。它在无源或双功放工作模式间提供灵活选择，以满足不同的调整要求或应用场景。NL4 Neutrik Speakon® 连接器支持多个扬声器的环路连接，系统扩展可轻松实现。
