This is the part two of previous blog . Most of you know there is a sweet spot to hear the best sound from your speaker system. Below are some examples of sweet spot for different sound system setups. First, the stereo two speakers system:
For 5.1 surround sound speakers see here:
Even more speakers? No problem. Here is how you divide positions of them. You get the idea.
Why they arranged this way ?
We mentioned how artists, engineers and producer recreate the sound stage in film and music to tell stories. In order to hear that result at any home or theater. We need a standard to arrange the speakers. There are many arrangements experimented throughout years begin from 1940's by Disney.
This film featured a Bumblebee flying in the theater. To achieve this sound effect Disney placed speakers around audiences. Meanwhile in music, The Beatles was the first to use stereo recording to produce music. After years of speaker arrangement experiencements. Two arrangements stereo and 5.1 survived and became the popular standard.
What is STEREO audio?
Do you ever wondering why we hear the singer in the center when the speakers are actually placed at left and right. The voice you heard is created by our brain after hear two identical sound from both speakers at exactly the same time. We call this effect psychoacoustic or phantom center.
This allow two speakers to create three sound sources left, right and center. This is the main reason stereo recording is the most popular and standard audio format. But what if you are moving around and not in the sweet spot? When you are not in the sweet spot the soundwaves from the left and right speakers will not arrive to your ear at same time and same loudness. Therefor, the center voice will shift to the louder side of location your ears hear. This also applies to surround sound speaker arrangement.
OPSIS II carefully arrange two speakers close together to give you the MAX sweet zone in the room. When you place OPSIS II at the right location in your room as shown below.

這是先前博客的第二部分。你們中的大多數人都知道從揚聲器系統聽到最佳聲音的最佳位置。以下是一些適用於不同聲音系統設置的最佳示例。首先，立體聲兩揚聲器系統：
對於5.1環繞聲揚聲器，請參見此處：
還有更多的揚聲器？沒問題。這是劃分位置的方法。你明白了。
他們為什麼要這樣安排？
我們提到了藝術家，工程師和製片人如何在電影和音樂中重現聲音舞台上的故事。為了在任何家中或劇院聽到該結果。我們需要一個標準來安排揚聲器。迪士尼從1940年代開始就嘗試了許多年來進行的安排。
這部電影的特色是大黃蜂在劇院裡飛翔。 為了達到這種音效，迪斯尼在觀眾周圍放置了揚聲器。 同時，在音樂方面，甲殼蟲樂隊是第一個使用立體聲錄音製作音樂的人。 發展了多年後立體聲和5.1的兩種編排倖存下來並成為流行的標準。
什麼是立體聲音頻？
您是否想知道為什麼當揚聲器實際上放置在左右時，我們會在中間聽到歌手的聲音嗎？您聽到的聲音是由我們的大腦在聽到完全同時揚聲器發出的兩個相同聲音後產生的。我們稱這種效應為心理聲學或幻覺中心。
這允許兩個揚聲器創建左，右和中置三個音源。這是立體聲錄音受歡迎和標準的音頻格式的主要原因。但是，如果您四處移動而不是在最佳位置呢？當您不在最佳位置時，左右揚聲器發出的聲波將不會同時且以相同的響度到達您的耳朵。因此，中心聲音將移到您耳朵聽到的位置的較大一側。這個到原則也適用於環繞聲揚聲器的佈置。
OPSIS II小心地將兩個揚聲器並排放置產生獨特的音場，將OPSIS II放置在房間如下所示的正確位置時以使您在房間內擁有最大的深度聆聽區域。
