我想問下, 其實靜電屏風有咩功效用途架 ?

問得好，只要配搭得宜，靜電喇叭比較容易獲得無箱聲、音質純正、音色準確、音場透明、細微細節多，唔好處就是音壓細，低音速度比較慢，歌者口型大。

可否簡單一點解釋一下。
上面冇嘢的，
但個網咁高，主要作用是什么？

但個網咁高? Well, it is not a net.  It is a diaphragm sandwiched between two grids, very thin.  It needs the area to produce sound.  The larger it is, the better sound it produce. Please see below:

Don't really need to know the working principals behind..hehe.  ESL (electrostatic) speaker's diaphragm needs a voltage charge to drive the diaphragm (force to move the diaphragm will make sound). That is why it need to plug into AC wall outlet.  Trying to explain it simply.  It sounds totally different from speakers we are used to listening.  More open and transparent, well define sound stage..means it sounds better.  Drawback is lack of bass , a bit thin on extreme highs, requires more power to drive and lower maximum sound pleasure produced (Don't sound very loud).  Overall, sounds better than "normal" speakers to me, but cost much higher.

auraheart説得無錯！我試下用最簡單説明，Martin  Logan的靜電喇叭理論與其他靜電喇叭無異，也是三明治式的結構。前、後二片極板中間夾著二片振膜。振膜連著電源插頭供給的電，而前、後二片極極是連接著喇叭插孔所入的訊號。當然，它們都必須經過一個變壓器來昇壓，始能夠獲得一萬伏特的高壓！電壓雖高，電流非常微弱，所以是非常安全。Martin Logan將前、後二片綱狀極板上面焗上一層絕緣的尼龍化合物，這種絕緣體可以承受三倍的靜電電壓。所以，當Martin  Logan靜電喇叭在播唱時，那二片極板是可以摸而不會觸電，那層黑色的絕緣體除了絕緣外，還有一作用，就是抑制那二片極板的振鈴作用，使得聲音不受音染。

ESL speakers are generally very good..very low harmonic distortion too...just sweeter sounding..just sucks when lows starts to roll off too early..lol..

打掃麻q煩

Not very ideal in HK unless air conditioning on at all time.  Humidity, conductive particles, insects/bugs, dust, even polluted air will damage the speakers over time.   Not nearly as heavy duty as regular speakers.  Young kids might even punch thru the panel.
