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低音炮是完整的由MartinLogan團隊實現多年的工程設計,結合先進數字信號處理,放大,電氣系統設計和房間校正的最新創新。

BalancedForce®對齊

反對鋁元件低音單元用於深,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匹配強大的專有開關放大器,令人難以置信低音揚聲器驅動器產生嚴格定義的低音,同時將失真保持在盡可能低的水平。 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)使用電腦和麥克風在整個聆聽環境中聆聽並定制sub對房間獨特聲學特性的表現 - 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

幾乎每個樓層都有定制的低通濾波器在過去的30年裡發布了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

通過牢牢按住煙熏玻璃來進入頂部安裝的控制面板面板。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 Stealth Series Vanquish and Axis Speakers Reviewed

"The MartinLogan Stealth line of architectural speakers impressed me. Their build and component quality is significantly high. It is obvious that much thought went into the design of these speakers, and the results are ultra high-end. MartinLogan has created a quality product that will provide a proud sense of ownership. When coupled with the BalancedForce 210 subwoofer, the sum performance was greater than any one speaker's individual achievement. I used to avoid my family room... However, thanks to the addition of the Vanquish and Axis speakers, I now find myself wanting to watch movies in the family room. I would highly recommend this product if you are considering an architectural speaker solution for your space"

MartinLogan Balanced Force 210 Subwoofer

"I can’t claim that the MartinLogan BalancedForce 210s are the end-alls in low-end reproduction, or that they will fool you into thinking there is an actual standup or electric bass sitting in your living room. What I can say is that they have brought me much closer to the real thing and made me a believer in subwoofing. Now that the 210s are in my listening room, my music–and not just music where bass is prominent–has taken on a new life. They have made a far greater difference in my stereo than any other component I can remember in a very long time. If you have a large room or really feel the need to hear low bass, the BalancedForce 210s are essential tools to getting the most out of your music."

This sub is the most amazing sounding sub I have ever heard, the sound matches perfectly with my main speakers ESL11a. It’s a little pricy but worth every penny, you cannot find a better subwoofer to blend with Martin Logan speakers. It’s a must have part of any electrostatic panel speaker. I wish the color match to my ESL11a was better, both are dark cherry and two totally different shades, but the finish is pristine and a very nice component to showcase with other ML speakers, looks defiantly make this sub have the WOW factor.

Seamless extension to the lowest octave of human hearing
I used to work in the field of engineering acoustics, including some work in speaker evaluation using impulse functions. When I saw that Martin Logan was selling some subwoofers that were capable of custom tuning using what appeared to be a familiar technique, I had to have one. The PBK space averaged transfer function that they appear to be using just begged to come home with me. So I bought the BalancedForce 210 and ordered the PBK accessory to be delivered later. I thought this set up would have really excellent "play value" for someone with my interests. It was my plan to mate this subwoofer to my Theos main speakers in a two channel system. I noted that Martin Logan has a custom function that can be downloaded to effect this pairing, and I intend to install the proper file later. I am writing this note today because, following the instructions in the BalancedForce 210's owner's manual, I was able to pair the subwoofer with the Theos beautifully, and without resorting to downloading any files or using the PBK accessory. I will look forward to doing these future tweaks, but for now I am wrapped up in very pleasant listening. The Theos are quite good, have a +/- 3 dB limit at about 43 Hz. The 210 allows you to pick up the next lower octave of program content. Many two channel sources have very little, or even no acoustic content in this lowest audible octave, but for many recordings, the lowest audible octave adds richness and reality to things like large drums, very low bass notes from organs, electric basses, acoustic basses, synthesizers, organs, and the like. I've played through several cds today, and I think there were noticable improvements that I could hear in every case. Most of the musical program material that I selected was chosen for my love of the music. But eventually I had to try some recordings that present special challenges to reproduction equipment. The most notable of these was Paula Cole's "This Fire." I have NEVER before heard a believable playback of the first cut, Tiger. There are a couple of bass segments on this cut that will cause every other speaker, including the unaugmented Theos, to crash and burn. The Theos augmented by the 210 breezed through this cut, including all of the absurd infrasonic bits that accompany the audible low bass notes. I like this subwoofer better than I thought I would. Its low frequency cut off limit is 30 Hz, so this allows it to "get out of the way" of the Theos very effectively, and they mate up exceedingly well. The stock settings of 90 degrees for phase, 0 for the 25 Hz boost/cut setting, 4 for the level setting, and 30 for the low frequency limit setting seem to be hard to improve on. I look forward to being proven wrong when I get around to downloading the Theos matching file, and going through the PBK set up. I would buy this component again without reservations.
