双8英寸2分频号筒装载高输出扬声器，40° x 30°号筒
PD743i精准指向性™扬声器可在传统单驱动器设计所无法覆盖的远距离处提供高效能的声音加强。单个模块在50米（165英尺）距离处可产生大于104 dB SPL（连续）的声压级。PD764i-215可与其他PD系列模块组成阵列使用，或单独用作分布式系统的组成部分。

特点
- 40° × 30° 覆盖角度 – 对称的前向尺寸允许在阵列中进行水平或竖直方向的安装。
- IFS™ 无干涉叠加双高频驱动器模块消除破坏性干涉，输出提升 6 dB。
- 双 2432H 压缩驱动器，配备 3" 振膜
- 双 CMCD-82H 8" 号筒负载锥形中频驱动器输出比传统设计高 6 dB。
- 图案控制维持在 400 Hz 以下。
- 同轴中/高频模块布局改进了中频可阵列性并降低了尺寸。
- 集成吊装系统简化了阵列设计和构造。
为提高在恶劣天气条件下的可靠性并减少水分侵入，WRC 和 WRX 型号的机柜尺寸可能与标准型号有所不同。如需 WRC 和 WRX 型号的图纸和/或尺寸信息，请联系 CustomAudio@harman.com。
