这个强劲的低音炮结合了10吋长冲程低音单元和一个峰值功率550瓦的BASH放大器，都包装在一个槽管箱体里。低频低至26Hz，意味着这个低音炮能在超高电平下提供超现实的声音表现，在提供最低音频信号时还保持着音乐性。前置音量控制方便调节。

　　因为Sub 550下潜那么低，它使用了边界增益补偿电路来补偿低频时房间的影响。
技术
BASH Amplifier
　　This subwoofer features the highly efficient BASH® amplifier technology, which combines the musical quality of class A/B amplifiers with the efficiency of class D amplifiers. BASH® technology translates into more efficient, yet more powerful amplification without the heat associated with conventional amplifiers. 

　　This subwoofer also feature a convenient on/auto/off switch and built-in limiter, which means that sound reproduction will always be clean and as well defined as intended.
边界增益补偿
　　边界增益补偿可以帮助传递非常线性的房间低频相应。它在低频段补偿房间的影响，因为每一间房间都会将最低的频率放大。 房间对低频放大的大小程度取决于房间本身以及您所在的听音位置——一般来说，您靠墙越近，房间对低频放大的影响便越大。 这就有可能产生过高的低音电平，从大约60Hz开始频率越向下增加得越大。 在20-30Hz的范围内，在一间普通的房间里峰值可提高5-10分贝。这样给人的第一印象是效果的确很吸引人，但声音会变的“隆隆作响”而令人讨厌，尤其是在听音乐的时候。

Level, Phase and Cut-off
　　Continuously variable level, phase and cut-off frequency controls make it easy to tune the subwoofer to integrate with virtually any speaker on the market, as well as allowing different placements and personal preferences
Limiter
　　A limiter prevents high input signals from overloading the subwoofer amplifier. It guarantees that the subwoofer will always be fully in control and that the sound will remain clean and clear, no matter how hard the subwoofer is driven.
窄槽式倒相箱体
　　窄槽倒相式是这些低音炮构造中独特的部分。设计用来加强侧面，使得整个箱体异常坚固。它还允许用更大的导管面积实现更低的频率调谐，与传统的圆孔相比，既高效率又低失真。
Speaker Level In
　　This subwoofer features speaker-level inputs, which is vital if your amplifier/receiver lacks a subwoofer line output.
　　The subwoofers also have both left and right line-level inputs (for stereo sources) plus a "loop-through" capability to allow the signal to be routed through to a second subwoofer.
