JBL GC15 是一款高品质扬声器，专为酒吧、俱乐部和音乐餐厅等娱乐场所的现场音响扩声而设计。
JBL GC15 采用 1.5 英寸专利 D2 双振膜双音圈压缩驱动单元，无论在高声压还是低音量聆听条件下，均能确保高频平滑延伸且失真极低。配备 15 英寸低频驱动单元，JBL GC15 能够重现更宽广的频率范围，提供更平坦的频率响应曲线和更低的失真率。全新设计的分频网络进一步提升声学性能，确保低频和高频驱动单元之间的无缝过渡，从而实现清晰、层次分明且高保真的音乐重放。
JBL GC15 采用耐用的桦木胶合板制成，可有效消除箱体共鸣并改善低频响应。支持无源或双功放模式，可灵活满足不同的调音要求与应用场景。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。
