Sub 300

Designed to perfectly complement high-performance multi-channel setups in smaller to medium sized rooms, the Sub 300 brings true Dynaudio sound quality and real deep bass augmentation to any audio-video system in a relatively compact and most convenient to use package.

The Sub 300 utilizes a high-tech 10" woofer with a pure aluminium voice coils and a powerful magnet system.
It is powered by a 250 Watt amplifier featuring the Dynaudio CEC circuit, and is integrated into the characteristic metal baffle in a fairly compact cabinet fitted with a downward-firing port to deliver even deeper bass extension. The airflow-optimized port was specifically designed for noise reduction by minimizing air turbulence.

Dynaudio also provided the Sub 300 with the full feature set of remote control functionality with all adjustments for selecting level, phase, cross-over frequency, or extended bass mode, and the four individual subwoofer setting memory presets.

The back panel contains RCA and XLR inputs and outputs, the master/slave switch, and the memory protect switch as found on the Sub 500 model.
