终极性能低音炮

您有可能在某些时候阅读或听到过将低音炮添加到静电扬声器周围的系统几乎是不可能的。虽然这不一定是真的(我们有低音炮来证明它),但这个想法是以经验为基础的。多年来,低音炮和静电器并没有很好地融合。打开潜水艇,也许你得到了更深刻,更强劲的低音你想要的但是那个美妙的静电按扣和中音清晰度,如果没有消失,现在会被涂抹和断开。

当我们开始我们的第一个低音炮项目时,我们的目标是提供好东西 - 深沉,紧凑,强劲的低音 - 而且没有坏事。我们想要制造超低音扬声器,当与超快速静电或传统的锥形扬声器结合使用时,可以无缝地融合到频率极端的最底层。 BalancedForce低音炮是完整的由MartinLogan团队实现多年的工程设计,结合先进数字信号处理,放大,电气系统设计和房间校正的最新创新。

BalancedForce®对齐

反对铝元件低音单元用于深,干净的低音

双低失真低音扬声器将高功率磁铁结构与10英寸和12英寸铝制锥形振膜配对,可提供巨大的偏移和声音输出,同时保留微小的低音细节,所有这些都没有一丝失真。锥形材料卓越的阻尼特性确保了与高分辨率全频扬声器无缝融合所需的平滑,非共振响应。

BalancedForce 212

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。

放大器设计

先进的超高效D类放大器

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。

PBK室内校正和25Hz电平控制

虽然正确放置在优化超低音扬声器性能方面起着关键作用,但定位超低音扬声器通常需要妥协。可选的MartinLogan Perfect Bass Kit(PBK,另售)使用电脑和麦克风在整个聆听环境中聆听并定制sub对房间独特声学特性的表现 - 产生干净,强劲的低音,直至最低频率。

此外,内置的25Hz电平控制允许听众将超低音扬声器输出调整±10dB,并通过在20至30Hz范围内切割输出来补偿过多的房间增益,或者通过增加那些来强调低音能量的感觉频率。

自定义低通滤波器
个人扬声器型号

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。

美丽的装饰

高光黑色橱柜和顶部装饰是标准配置。顶部饰边有多种可选的高光,硬木和实木贴面饰面。

密封柜

尽管端口是增加低频输出的一种方便且经济的方式,但它们对谐振能量的依赖会降低低音质量。无论音乐或电影源材料如何,BalancedForce超低音扬声器的密封系统都具有较少的瞬态模糊群延迟,同时保持平滑,一致的响应。

多输入选项

用于无缝系统集成的同时LFE和双通道连接

强大的连接和控制系统允许同时连接2声道立体声音乐和多声道家庭影院,并允许每个声源具有单独的分频和电平设置,使听众在每个应用中都能获得完美的演奏。通过RCA或XLR的LFE输入有效地不使用低通滤波器,而是将交叉控制留给处理器。左右RCA,XLR和扬声器电平输入集成了离散的用户可调节或扬声器特定的定制安装的发烧级低通滤波器,可在播放双声道音乐时提供不同的电平和交叉点。

顶部安装的控件

顶部安装的控件分别隐藏在烟熏玻璃重点面板下方,可轻松调节重低音扬声器的设置。

无限制的调整

通过牢牢按下烟熏玻璃来进入顶部安装的控制面板面板。您将找到所有标准的低音炮控制,如Level,Low-Pass Filter和Phase,以及MartinLogan独有的一些。

独特的音调扫描功能可帮助用户定位听音室中可能出现麻烦的嘎嘎声或共鸣的区域。只需按一下按钮,听众就可以启动120-20Hz的音调扫描。如果在房间内发生拨浪鼓或共鸣,则按下该按钮可保持当前频率,从而允许听众调查并识别信号源。

“开/自动(触发)/关闭”开关控制超低音扬声器的节能功能。 “开”设置可防止子进入节能模式。当设置为“自动(触发)”时,子音将在检测到音乐信号时打开,并在几分钟后没有信号时关闭。如果连接了12伏触发器,触发设备将打开和关闭超低音扬声器。

定制能量传递耦合器(ETC™)尖峰可提供更大的灵活性,可增强厚地毯的稳定性,或在低音炮和地板之间创建更紧密的耦合,从而提高整体音质。

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.
