AM7212/64是一款高功率、轻量化的2路全频扬声器系统，由采用JBL Differential Drive差分驱动技术的双音圈、双磁隙2262H 300毫米（12英寸）低频驱动器和2432H高频驱动器（38毫米/1.5英寸喉口、75毫米/3英寸音圈压缩驱动器）组成。大尺寸Progressive Transition渐进过渡波导可在多种覆盖角度下提供卓越的声场覆盖。波导可旋转，因此该扬声器系统可垂直或水平安装。高斜率被动分频网络可将频带重叠降至最低。离轴响应控制良好，进一步提升了阵列组合能力。
为提高恶劣天气条件下的可靠性并减少水分进入，WRC & WRX 型号的箱体尺寸可能与标准型号尺寸不同。如需 WRC & WRX 型号的图纸和/或尺寸信息，请联系 CustomAudio@harman.com。
