Fitment Note

The DXO300+ is a line-level signal processor and does not power speakers directly. It should be connected to compatible amplifiers, powered speakers, or other downstream audio equipment.

In Stereo 2-Way mode, the incoming stereo signal is divided into low- and high-frequency outputs. In Mono 3-Way mode, the signal is divided into low-, mid-, and high-frequency outputs.

Crossover frequencies should be selected according to the specifications of the connected speakers, subwoofers, drivers, and amplifiers. Incorrect crossover settings can reduce system performance or place unnecessary stress on speaker components.
