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.

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

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。
 

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.
