SUB 250有非常平坦的频率响应，与传统的低音反射式超低音相比，它能以一种非常有力的方式播放低频信号，频率响应一直延伸到150Hz。这点很重要，因为许多超低音炮的频率输出在100Hz左右陡降（有些型号更低），这样它们就很难与小音箱匹配。

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。
\SUB 250 driver
At the heart of this powerful subwoofer is a long-throw super driver, capable of moving large amounts of air with incredible speed and precise control. The 8in driver feature Ø 38mm/1.5in four-layer voice coil. The heavy magnet systems feature a vented pole piece in order to avoid over/under pressure behind the dust cap (mechanical damping) when the cone is moving. This unit is an important part of the reason why the subwoofer offer top specifications and peak performance.
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.
相位和截止频率控制
连续可调的电平、相位和截止频率控制装置使它更易调节低音炮，使其真正适合市场上任何音箱，也使低音炮可放于不同位置及根据个人爱好调节。
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.
