EVH 两分频全频号角负载扬声器

覆盖范围控制低至500hz，高性价比两分频配置

由负载低音扬声器的25英寸大型号筒实现500 Hz控制——扬声器的额定覆盖角度始终保持在500 Hz。
该控制尤其适用于混响时长（T60）中频段超过2-2.5秒的场合，此类场合中，将更多声音投射到吸音观众处并减少投射到反射表面的声音，从而增加语音和音乐的清晰度。常见的12或15英寸前置低音扬声器覆盖角度扩展低于2-3 kHz，并且会传送中音到反射表面上，无法实现500 Hz控制。
500Hz 控制的波束边界也能保证音质，也就是说垂直覆盖角度较低边缘处的听众与靠近扬声器瞄准轴的听众所接收到的频率平衡大致相同。
500Hz控制能够减少舞台“溢出”，减少扬声器群下可能出现的声音反馈。
六种覆盖模式有助于方案设计。
保证最大声压级输出和极低失真度。
可以主动分频，但其专业的内部分频/均衡器网络能够实现低成本被动分频工作。
以下三种型号有黑白两色可选：EVCoat（室内用）、PI（非直接露天用）、FG（玻璃纤维-直接露天用）

FRX及FRX+系列在全球获得的成功证明了Electro-Voice 采用的同轴号角负载式扬声器方案适用于各种规模的场地。EVH系列将这些经验全都融入到新的音响应用安装专用解决方案中。EVH体现出一种独特的设计理念：在15英寸中等尺寸两分频同轴号角负载配置中始终保持低至500Hz的指向性控制，展现其出色价值的同时实现高度装配灵活性和六种覆盖模式（范围从40ºx30º到90ºx90º）。

EVH扬声器是低音单元和压缩驱动单元的有机组合。 EVH-1152S配备一个SMX2151 15英寸400W低音单元和一个在12" 方形波导上的ND2B中型2英寸振膜40W高频压缩驱动。 EVH-1152D采用相同的低音单元和全新的DH7N大尺寸压缩驱动，该压缩驱动配有3英寸振膜和钕磁结构。该优质组件实现了动态性能增强，减少失真，压缩功率。
