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 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。
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。
"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"
"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."
要使用揚聲器運行Anthem Room Correction（ARC），您需要購買PBK或ARC套件（請注意，MartinLogan Perfect Bass Kit（PBK）麥克風與MartinLogan揚聲器的Anthem Room Correction完全兼容）。每個套件都附帶一個獨特的麥克風。
要下載最新版本的ARC，請單擊下面的鏈接直接訪問Anthem的網站。
ARC Genesis requires an ARC or PBK Microphone, a Mac OS X (10.12+) or Windows (7/8/8.1/10) computer, and an ARC or PBK compatible audio product. One USB port is required. If you are using a laptop computer, check power settings and battery meter before starting to ensure the procedure is not interrupted.
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.
