Designed for ground stacked applications, SUB 900 is the perfect choice whenever a powerful lower extension is required.

A 900 W RMS Class D Digipro G3 power amplifier ensures advanced efficiency as well as forcible sound pressure levels up to 134 dB.
SUB 918 is enabled for real time monitoring and remote control via RDNet protocol and Aurora Net software (Windows and Mac), allowing advanced subwoofer configurations alongside with perfect low-end matches with dBTechnologies’ full-range systems enabled to RDNet communications.
