It does. lol

See in the pic under DBO where it says "HP Freq"? That's the subsonic filter.

"Dynamic Bass Optimization (DBO): The Dynamic Bass Optimizer (DBO) is used to enhance low frequency reproduction in your vehicle. Conventional bass-boost circuits only increase bass at a fixed frequency, and cause the amp to consume considerable power. The DBO allows you to adjust the frequency (20Hz - 80Hz), as well as the boost level (up to 12dB), allowing you to fine-tune the bass in your system to optimize performance. The frequency control is a high-pass filter which can be used as a subsonic filter."
