BalancedForce 212

終極低音

BalancedForce 212基於原始Descent的突破性技術,結合了新功能和增強功能,可簡化系統集成,同時提高性能。其標誌性的雙驅動器強制消除配置幾乎消除了低音模糊的機櫃共振。每個堅固的定制鋁錐驅動器都由先進的基於DSP的高功率放大器驅動。結果是動態的,無限制的輸出到最低頻率,但清晰度和清晰度接近靜電傳感器。

終極性能低音炮

您有可能在某些時候閱讀或聽到過將低音炮添加到靜電揚聲器周圍的系統幾乎是不可能的。雖然這不一定是真的(我們有低音炮來證明它),但這個想法是以經驗為基礎的。多年來,低音炮和靜電器並沒有很好地融合。打開潛水艇,也許你得到了更深刻,更強勁的低音你想要的但是那個美妙的靜電按扣和中音清晰度,如果沒有消失,現在會被塗抹和斷開。

當我們開始我們的第一個低音炮項目時,我們的目標是提供好東西 - 深沉,緊湊,強勁的低音 - 而且沒有壞事。我們想要製造超低音揚聲器,當與超快速靜電或傳統的錐形揚聲器結合使用時,可以無縫地融合到頻率極端的最底層。 BalancedForce超低音揚聲器是MartinLogan團隊多年來的工程設計的完全實現,結合了先進數字信號處理,放大,電氣系統設計和房間校正的最新創新。

BalancedForce®對齊

反對鋁元素低音單元或深,乾淨的低音

雙低失真低音揚聲器將高功率磁鐵結構與10英寸和12英寸鋁製錐形振膜配對,可提供巨大的偏移和聲音輸出,同時保留微小的低音細節,所有這些都沒有一絲失真。錐形材料卓越的阻尼特性確保了與高分辨率全頻揚聲器無縫融合所需的平滑,非共振響應。

BalancedForce 212

這些低音揚聲器以“BalancedForce”配置間隔180度,完全相反,可消除失真,從而導致機箱振動並提供純正的低音能量。傳統的低音炮外殼受到與錐體運動相同且相反的反應,在機櫃內產生聲學振動。通過觸摸機櫃你感覺到這一點。雖然這種現象的“物理”實際上會導致低音炮音箱產生共鳴甚至跳舞,但大多數超低音揚聲器設計師都會將重量或質量應用於音箱以減少這種干擾,但仍會留下一個副產品 - “模糊低音”。 BalancedForce是一種優雅簡單的解決方案,可以消除聲學方程中機櫃振動貢獻的變量。

BalancedForce 212

放大器設計

先進的超高效D類放大器

BalancedForce subs配備功能強大的專有開關放大器,配有令人難以置信的低音揚聲器驅動器,可產生嚴格定義的低音,同時將失真保持在最低水平。 BalancedForce 210採用850瓦D類開關放大器,峰值功率為1700瓦,效率超過90%。 BalancedForce 212具有雙850瓦放大器(每個低音揚聲器一個),總系統功率為1700瓦(3400瓦系統峰值)。

低噪聲,高功率變壓器和開關電源具有高質量的MOSFET晶體管,噪聲抑製網絡和控制電路,可提供極高的電流水平和極低的失真水平。分離電源軌可最大限度地減少失真,同時最大限度地提軍用級玻璃環氧樹脂電路板,溫度傳感器和保護電路可確保高質量的聲音和可靠的無故障運行。

PBK室內校正和25Hz電平控制

雖然正確放置在優化超低音揚聲器性能方面起著關鍵作用,但定位超低音揚聲器通常需要妥協。可選的MartinLogan Perfect Bass Kit(PBK,另售)使用計算機和麥克風在整個聆聽環境中進行聆聽,並根據房間獨特的聲學特性調整潛水艇的性能,從而產生乾淨,強勁的低音,直至最低頻率。

此外,內置的25Hz電平控制允許聽眾將超低音揚聲器輸出調整±10dB,並通過切斷20至30Hz範圍內的輸出來補償過多的房間增益,或通過增加那些來強調低音能量的感覺頻率。

自定義低通濾波器
個人揚聲器型號

定制的低通濾波器可用於過去30年內發布的幾乎所有落地式MartinLogan揚聲器。這些可選的自定義濾波器可調節超低音揚聲器的低通設置,以便與各個揚聲器型號的滾降特性無縫融合。過濾器可通過USB拇指驅動器的用戶友好過程輕鬆安裝,並可免費下載。目前有許多獨特的過濾器,隨著新的揚聲器發布,將添加額外的過濾器。

美麗的裝飾

高光黑色櫥櫃和頂部裝飾是標準配置。頂部飾邊有多種可選的高光,硬木和實木貼面飾面。

密封櫃

儘管端口是增加低頻輸出的一種方便且經濟的方式,但它們對諧振能量的依賴會降低低音質量。無論音樂或電影源材料如何,BalancedForce超低音揚聲器的密封系統都具有較少的瞬態模糊群延遲,同時保持平滑,一致的響應。

多輸入選項

用於無縫系統集成的同時LFE和雙通道連接

強大的連接和控制系統允許同時連接2聲道立體聲音樂和多聲道家庭影院,並允許每個聲源具有單獨的分頻和電平設置,使聽眾在每個應用中都能獲得完美的演奏。通過RCA或XLR的LFE輸入有效地不使用低通濾波器,而是將交叉控制留給處理器。左右RCA,XLR和揚聲器電平輸入集成了離散的用戶可調節或揚聲器特定的定制安裝的發燒級低通濾波器,可在播放雙聲道音樂時提供不同的電平和交叉點。

頂部安裝的控件

頂部安裝的控件分別隱藏在煙熏玻璃重點面板下方,可輕鬆調節重低音揚聲器的設置。

無限制的調整

通過牢牢按下煙熏玻璃面板,進入頂部安裝的控制面板。您將找到所有標準的低音炮控制,如Level,Low-Pass Filter和Phase,以及一些MartinLogan獨有的。

獨特的音調掃描功能可幫助用戶定位聽音室中可能出現麻煩的嘎嘎聲或共鳴的區域。只需按一下按鈕,聽眾就可以啟動120-20Hz的音調掃描。如果在房間內發生撥浪鼓或共鳴,則按下該按鈕可保持當前頻率,從而允許聽眾調查並識別信號源。

“開/自動(觸發)/關閉”開關控制超低音揚聲器的節能功能。 “開”設置可防止子進入節能模式。當設置為“自動(觸發)”時,子音將在檢測到音樂信號時打開,並在幾分鐘後沒有信號時關閉。如果連接了12伏觸發器,觸發設備將打開和關閉超低音揚聲器。

定制能量傳遞耦合器(ETC™)尖峰可提供更大的靈活性,可增強厚地毯的穩定性,或在低音炮和地板之間創建更緊密的耦合,從而提高整體音質。

MartinLogan BalancedForce 212 subwoofer

"The BalancedForce 212s are so flexible that I can imagine them—used in almost any room, and with almost any speaker—restoring the tactile impact and low-end reach that other subs usually leave by the door... Whether or not you have MartinLogan speakers to pair them with, I strongly, strongly recommend the BalancedForce 212. It's definitely not a tubby thumper, and no imagination is needed, because nothing is missing. "

MartinLogan BalancedForce 212 Subwoofer

"The BF212 is one of those rare subwoofers that can be described as essential. It delivers uncompromised bass with clarity, accuracy, and an utter lack of colorations. Once it’s been tuned to a room with ML’s Perfect Bass Kit, there’s a high likelihood that you’ll never need another sub. Never… it is my judgment that the BalancedForce 212 is in a class with the best subs available to the home-audio enthusiast. The BF212 is one for the short list -- it’s required listening for anyone who’s dead serious about the low end. Highly recommended."

—Kevin East, SoundStage! Hi-Fi

THE BEST SUBWOFER IN THE WORD

GW1800

  • 2018年2月15日星期四

Let me just say straight out that I’m a believer in subs - actually a pair of subs. I know not all will agree. There are good reasons in the past to not incorporate subs but I think now those reasons are moot unless just the thought of having a sub is troublesome which some claim. There has been forever the mystique about full range speakers but very few can really get the job done and besides the ones that do most of us can’t afford anyway. Volumes of air needs to be moved and small cones or multiple thereof just come up short. Also that low end load can put a lot more strain on your amp to drive to the lower frequencies. Having a sub removes a great deal of that load so it can concentrate on 90% of the total sound much much better. Good bass to me is so essential and even though subs only handle the low end they seem to impact the whole sound way beyond its rather narrow frequency range. Good non-boomy bass is essential to the listening experience – period! In comparison bad bass can do the exact opposite probably even make the listening experience much worse than great bass improves. However as good as subs are today the troublesome issues as the ‘no sub for me crowd will tell you’ – better integration with the main speakers and room interactions are big problems left unresolved satisfactorly and they are right. This is exactly what the 212 does so well and so much more! I’ve had my 212’s for a few years now and they continue to amaze me in performance, looks and integration. I’m using these with a pair of CLX Art speakers and am very happy with how they round out the very bottom octave or so. I previously had a pair of Descent i’s with Summit X’s that I liked very much. However room placement was limited and I could never quite get comfortable with the bass produced in that room. There were plenty of adjustments on the Descent and Summit X’s but those adjustments came up short in my opinion. I blame it all on my room as since then I have moved them to a larger multi-channel room and they are performing very nice indeed. Since my choices for placement are very limited in the music room I needed a sub that could produce good bass where I put them. I can’t say enough about the PBK kit and the software that does exactly that and more. It’s quite easy to perform and you get to see on a graph just how a room is beforehand and the near perfect correction the software calculates – it’s just amazing! Combine this with the custom crossover that is available for most if not all ML speakers there now is some serious sonic improvements happening indeed! I’m familiar with the Descent i design with 3 cones and was a little troubled with the new 2 cone design. It seemed to me the design of the 3 cone was very well thought out so I was concerned with the change and why. Let me say that now that I have experienced the new design it is definitely an improvement at a very basic level. One thing that they did keep from the older design were the controls on top – smart and very convenient. So when you add it all up the much better integration of the sub to your room using the PBK kit, the custom crossover for the main speakers and the basic design improvements this is a real big step up on sub technology! Sub doubters beware you may have met your match!

Essential addition for large spaces, build quality is first rate
I have a pair of 212s teamed with Martin Logan Summit Xs to fill an open concept house with sound and the 212s are a key component to creating a unbeatable audio experience. After much research I concluded that my subwoofers needed to be precisely matched to my electrostatics, and the 212s were the answer. I have the 212s placed on the other side of the house from the Summit Xs but you would never know it as the lower frequencies appear to be coming from the Summit Xs. The 212s are not inexpensive, but the build quality and audio rewards are top notch, and it is a product that will last you for a few decades.
