这些低音扬声器以“BalancedForce”配置间隔180度，完全相反，可消除失真，从而导致机箱振动并提供纯正的低音能量。传统的低音炮外壳受到与锥体运动相同且相反的反应，在机柜内产生声学振动。通过触摸机柜你感觉到这一点。虽然这种现象的“物理”实际上会导致低音炮音箱产生共振甚至跳舞，但大多数超低音扬声器设计师都会将重量或质量应用到音箱以减少这种干扰，但仍会留下一个副产品 - “模糊的低音”。 BalancedForce是一种优雅简单的解决方案，可以消除声学方程中机柜振动贡献的变量。
BalancedForce subs匹配强大的专有开关放大器，令人难以置信低音扬声器驱动器产生严格定义的低音，同时将失真保持在尽可能低的水平。 BalancedForce 210采用850瓦D类开关放大器，峰值功率为1700瓦，效率超过90％。 BalancedForce 212具有双850瓦放大器（每个低音扬声器一个），总系统功率为1700瓦（3400瓦系统峰值）。
低噪声，高功率变压器和开关电源具有高质量的MOSFET晶体管，噪声抑制网络和控制电路，可提供极高的电流水平和极低的失真水平。分离电源轨可最大限度地减少失真，同时最大限度地提军用级玻璃环氧树脂电路板，温度传感器和保护电路可确保高质量的声音和可靠的无故障运行。
几乎每个楼层都有定制的低通滤波器在过去的30年里发布了MartinLogan扬声器。这些可选的自定义滤波器可调节超低音扬声器的低通设置，以便与各个扬声器型号的滚降特性无缝融合。过滤器可通过USB拇指驱动器的用户友好过程轻松安装，并可免费下载。目前有许多独特的过滤器，随着新的扬声器发布，将添加额外的过滤器。
"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."
要使用扬声器运行Anthem Room Correction（ARC），您需要购买PBK或ARC套件（请注意，MartinLogan Perfect Bass Kit（PBK）麦克风与MartinLogan扬声器的Anthem Room Correction完全兼容）。每个套件都附带一个独特的麦克风。
要下载最新版本的ARC，请单击下面的链接直接访问Anthem的网站。
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.
