Mirage OMNI 60 Loudspeakers: Measurements

由于本扬声器的独特的分散格局，除了我们的轴响应标准设置的测量，我们把增加了测量，显示，扬声器的输出为60，120和180度，另外三个轴的关系上（ 也就是说 ，在扬声器前面的）。其目的是展示如何将扬声器均匀地分散在前面的声音从扬声器的后方。为了得到这种测量，对轴的反应是减去区别在于显示离轴响应。ecause of this speaker's unique dispersion pattern, in addition to our standard set of measurements we have added three additional measurements that show the speaker's output at 60, 120, and 180 degrees off-axis in relation to the on-axis response (i.e., in front of the speaker). The purpose is to show how evenly the speaker disperses the sound from the speaker's front to the rear. To derive this measurement, the on-axis response was subtracted from the off-axis response with the difference being shown.

Chart 1 - Frequency Response and Sensitivity

Microphone measuring position: widest portion of WaveGuide, no grille

Sensitivity: 86.0dB (averaged 300Hz-3kHz, 2.83V/1m)

Additional Measurement #1
60-degree off-axis response deviation from on-axis response

Plot represents on-axis response subtracted from 60-degree off-axis response

Additional Measurement #2
120-degree off-axis response deviation from on-axis response

Plot represents on-axis response subtracted from 120-degree off-axis response

Additional Measurement #3
180-degree off-axis response deviation from on-axis response

Plot represents on-axis response subtracted from 180-degree off-axis response

莱科萨斯的Xd扬声器系统是一个四件主动系统由两个扬声器（的XDS），一个低音炮（XdW），和自己的专用amplifiier（的Xda）组成。除特别注明外，所有的测量是一个单一的XDS与XdW重低音扬声器，与XdW的低音炮在“3点钟位置”的“模式”，在的Xda开关处于领先地位，并配有100mV的输入信号。因为这是一个活动的系统，灵敏度，阻抗和电气相位测量不适用。
