Focus ESL C18是一款多功能性能架或壁掛式靜電中置聲道揚聲器，採用18英寸寬XStat CLS靜電傳感器，具有折疊式運動高音揚聲器的詳細成像能力，以及兩個6.5英寸低音揚聲器，帶來真實感。能夠低至50Hz的深低音再現。
荷蘭黃金時代的畫家在相機發明之前300年就製作了逼真的傑作。他們用明亮的，超凡脫俗的光線集中註意力。即使在他們最親密的肖像畫中，鉚接的光線也會引起你的注意。
這種感官焦點也是家庭影院現實主義的關鍵。中央聲道揚聲器的作用是將動作和對話固定在屏幕上。它必須重現詳細的高頻信息以加強成像，並且還與環繞聲系統中的其他揚聲器無縫融合，將您包含在逼真的聲場中。
MartinLogan推出全新的家庭影院現實主義傑作： Focus ESL C18中置聲道揚聲器，靜音中置聲道揚聲器，專為壁掛式靈活性而設計。
目標是靈活性和性能，Focus ESL C18實現了這兩者。光滑的雕刻外殼堅固支撐，無共振，均衡。它被設計為安裝在屏幕的上方或下方。包括重型壁掛式安裝支架硬件，創新支架可容納多個安裝角度，因此您可以將Focus ESL C18直接對準您的聆聽位置，以實現完美對齊的中央通道演示。
Focus ESL C18也在家中的架子或落地架上。切換方便的“On-Wall / Off-Wall”聲學輪廓開關，可即時優化任何安裝位置的性能。此功能會自動修改響應以補償可能增強或抑制低音輸出的牆邊界。結果是房間填充中心頻道再現與栩栩如生的全範圍神韻。
安裝靈活性和定制的中央通道性能：現在，您的Masterpiece家庭影院系統擁有比以往更多的選項。
是什麼讓Focus ESL C18成為中心通道設計和工程的傑作，它的壁掛式裝置令人驚訝。雖然Focus ESL C18的平板安裝在牆壁上時的深度僅為9.6英寸 ，但它採用了技術，可以通過高級中置聲道揚聲器提供您所需的詳細音頻。
7.5 x 18英寸曲線線源（CLS）靜電面板具有柔和的水平曲線，可增強輸出並擴展包絡中檔色散圖案。外部格柵的設計與MicroPerf Stators的外觀和Masterpiece ESL系列中其他型號上的大膽AirFrame Blade相得益彰，實現了複雜和協調的家庭影院系統美學。
使用5向發燒友WBT接線柱安全可靠地連接電子設備。它們的純銅連接板具有高導電性，不受渦流影響。這些接頭是絕緣的，可以防震，並且完全阻尼振動。它們為大型專業揚聲器連接提供了充足的空間。
Vojtko Voiced，Focus ESL C18的高級分頻器為這款巧妙的構圖增添了中等清晰度。這款分頻器採用最精細的聚丙烯電容器和空心線圈精心手工製造，採用了MartinLogan專有的Vojtko拓撲結構，可實現極低失真和無縫驅動器/ ESL集成。這種精確調整的網絡可以保留最微小的聲音細微差別，同時處理任何信號源的完整動態。
MartinLogan獨有的折疊式運動高音揚聲器位於靜電面板的後面，固定在一個設計獨特的外殼中。折疊式運動高音揚聲器的低質量振膜可最大限度地減少失真，同時其短的偏移長度可加快閃電般快速的高頻響應。 Focus ESL C18中央聲道揚聲器中的1 x 1.4英寸折疊式運動高音揚聲器的振膜面積為5.25 x 1.75英寸。靜電面板和折疊式運動高音揚聲器的綜合性能特性確保了精確和超逼真的前級混合。
這種中高頻性能只能通過巨大的低端基礎來支持。所以Focus ESL C18還配備了一個6.5英寸雙低音單元的無源陣列，可以低至50Hz的低音再現。可以使用聲學輪廓開關調整任何安裝選項的低音輸出。

The ESL C18 is an absolutely fantastic center speaker. I have Stewart StudioTek 130 electric projection screens and needed a wall mounted center channel speaker to go with my other Martin Logan speakers. This is the ultimate center speaker. Crisp, clear dialog and good off axis sound for people not dead center. I love this speaker!
In the past few months I have upgraded my center channel from the Stage X to the new Focus. Originally I had the new Focus paired with a pair of Summit X’s for a few months. I could tell right away that the new center channel was superior to the Stage X. How could I tell? It was pretty easy to tell that the new Focus just made movies or concerts sound more real and interesting then in the past. The center channel is the most important speaker in a multi-channel system so to get the best sound quality any improvements will be noticed immediately. If you look at the specs the horizontal dispersion is the same for both center channels but to me it’s wider on the new Focus. So sitting off axis works better in my room sitting arrangement – maybe it’s just that it’s longer than the Stage X. The other thing that I would like to mention is I had the Stage X sitting on top of my electronic cabinet with the back about 3” from the wall. This worked but an older different manufacturer (that I had in the past) had a way to mount the center channel directly to the wall. I always liked that look but even though the Stage X had a bracket that could be used to mount to the wall it would have been sticking out quite a bit more so I never mounted it that way. The new Focus is made to mount to a wall hanging on a very narrow bracket so really it sticks out just slightly deeper than the speaker itself. The Focus has a switch to configure the speaker exactly for direct wall mounting and if preferred not. I really like the look mounted directly to the wall. I also think because of the development work that ML did to make this even possible to wall mount (which probably was quite the trick with an electrostatic speaker) I just think the end result is very good sonically and visually. I also like the longer look of the Focus it kind of looks like the top section of a hybrid speaker on its side. It seems to match the rest of the front channels better visually. The finishing that I’m all too familiar with continues to be top notch indeed. In fact it looked so good I swapped out my Summit X’s (with stock black ash finish) to a special color 13a’s that match much more closely which I like a lot – both visually and sonically. I would also like to thank Shawn at DaVinci Media for all his help with this media room system upgrades and trade ins over the years!
Worth every penny. The Focus is one of the best sounding center channels I've ever had. It blends will with the masterpiece series speakers and previous generation MLs. I currently have this matched with my current Montis speakers and previous Theos both systems sounded excellent with movies, TV, video games, or anything surround sound. If you are on the fence about this speaker or want to upgrade from the ESL C don't even think twice, it is a night and day difference in improvement. Highly recommend.
