1. GEO 双曲面反射式波源

这种技术己获专利的双曲线反射式波源 Hyperbolic Reflective Wavesource (HRW), 能耦合凝聚一起, 连贯水平或垂直设置的GEO

系统的中高频能量. 并产生精确而且可预测的结果，这就是为什么

GEO的系统设置需得把箱间角度控制到0.01°那麽的精密度。HRW波

源（见下图）用声学反射镜面创建一个位于扬声虚拟声学波源. 它使真实的声源（压缩驱动器）器音箱之外的可以位于音箱

内部几乎任何地方而虚拟的声源则位于音箱背后。就其本身而言，

GEO波源的测量在数学预测和真实结果之间表现出高度的对应性

1. Hyperbolic Reflective Wavesource

NEXO GEO's patented, third generation Hyperbolic Reflective Wavesource (HRW), redefines controlled dispersion of acoustic energy, and achieved the precision that inter-cabinet angle settings can goes down to o.o1° when covering very long throws! Technically, the legendary HRW controls acoustic energy using an acoustical reflector (i.e. mathematically calculated hyperboloid acoustic mirror, derived from rigorous geometrical transformations) that is functionally positioned "outside" the loudspeaker cabinet.

2. 指向性相位组件

力素GEO指向性相位组件Directivity Phase Device (DPD), 使GEO 的模组能投放强劲的中-低频输出于单一单元之上. 以GEOS12的使用

为例, 它使用了一个12英寸锥体低频扬声器和一个1英寸压缩驱动器，

因此低频单元必需要工作至高达1200Hz. 实际上，我们不能期望

两只12英寸低频扬声器中心点之间的距离小于10英寸，否则在1250Hz

以上它们将会相距达整整一个波长，而相邻的低频扬声器在500Hz(1/4 波长间距)时,已经开始变成分离的声源,在600Hz将显现出单独的波瓣。解决办法是在每个低频单元上安装上GEO指向性相位组件DPD（下图），它令12英寸驱动器的中高频表现好象是两个6英寸驱动器。 在 GEO S12系列中,DPD采取相位塞子的形式,附加到锥体换能器的框架上。

从下面的极性图可见加上了DPD后的12寸可用频率高至1250Hz. 再高些的频率开始出现干扰性副波. 而因为S12的分频点为1,100Hz,

所以那段频率是会被过滤不使用的. 简单来说是安装了DPD的S12,

于频率高于550Hz后会渐被看成好像2只6寸单元, 其中心相距不超过

其半波波长, 共挽地耦合凝聚整条阵列,成为线声源而工作至分频点.

而低于550Hz时则跟一般单一12寸低音重播无异.DPD为邻接低频L声器

之间的线声源耦合扩展了上限频率。就其本身而言，GEO系统的12英寸单元驱动器既不损失功率承受能力，也不损失低频扩展。另外,因为GEO

S12低频干扰效应很小,所以与大阵列相比,它按箱体比例具有更多的低音。

3.可配置的指向性组件

对于一般垂直阵列来说,都在非耦合面不能提供较好的近距离水平覆盖.很多的情况是十米以上需要较窄的水平覆盖, 十米以下则需要较宽的水平覆盖. 力素的解决方案

是一种可配置的指向性组件Configurable Directivity Device (CDD),  它以面加形式加于阵列里每个音箱非

耦合面的中/高频覆盖角度板之前,可设为为80°或120°, 因应场地水平覆盖的均平度对每一垂直阵列音箱来设置.

3. Configurable Directivity Device (CDD)

GEO D10's third design signature, the patented Configurable Directivity Device (CDD), is a diffraction slot used to control acoustic coverage in the "non-coupling plane" (the horizontal plane of a NEXO vertical tangent array system). The CDD consists of bolt-on flanges that can be user-changed to adjust the diffraction slot's exit flare rate at either 80° or 120°. GEO D10 ships in the 80° configuration, with 120° flanges included. Place each cabinet with the flange according to coverage design & spray.

2.  Directivity Phase Device (DPD)

The DPD extends upper frequency limits for line source coupling between GEO 's adjacent loudspeakers' woofer at the coupling plane, the adjacent woofers coherently couple as if there were twice as many loudspeakers of half the diameter, mounted at half the physical distance.Take a GEO S12 as example, it’s 12” woofer is to work all the way up to 1200Hz. Practically, we can’t have 2 12” woofers at adjacent cabinets’ distance between their mid points be less than 10”, otherwise they will have more than 1 wave length distance at about 1250Hz, and these sound sources will be at 1/4wavelength apart around 500Hz, these adjacent  sound sources actually begins to seperate. At 600Hz, they’re individuals. To solve this, NEXO introduce a DPD (see photo below) in the form of a phrase plug, which is to placed at dead centre infront of the woofer. This will made the woofer act liike two 6” woofers, from the diagram bellow you can tell the 12” x’overed at 1100Hz, beyond that should be filtered out. Briefly, the DPD will make the single woofer acted like two smaller units of half the diameter progressively at about 550Hz (for S12), thus their distance between centre be less than half wavelengths. These also helped coupling the coherency of the line sources. And below 550Hz, it acted as a normal 12” woofer (S12), and ithe DPD will not hampered the output power & efficency of the woofer, and extends coherency far below the "natural" mid-to-HF coupling limits common to traditional line array system designs.
