SUB650是为高水平音箱系统而生的。强劲的前冲式设计采用一只爆炸性的12英吋长冲程单元。SUB 650被安装在完全密闭的腔体里，从而远离了管口噪音。SUB650给你非常精确、牢牢受控的声音重放。对于设法重现现场音乐会和电影院的动态感受的发烧友和音乐鉴赏家而言，SUB650是理想之选。来自BASH放大器的650W峰值功率，24Hz到200Hz的频率范围，这些都让SUB650成为低音炮里的顶尖。

　　因为SUB650能下潜到令人难以置信的24Hz，我们采用了可变的“边界增益补偿”电路，确保与家庭环境的整合适配。SUB650增加了一个12V触发输入，在特制安装应用中尤其有用。
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.
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.
