SUB 918 features a single 18” woofer housed in a solid bass-reflex cabinet. The 900 W RMS Digipro G3 Class D amplifier ensures both maximum efficiency and significant sound pressure levels.
 The system is enabled for RDNet communication for complete real-time monitoring and control via Aurora Net software (available for Windows and Mac), which allows for advanced sub configurations and perfect matching with dBTechnologies full range systems enabled for RDNet control.
 All 900 Series subs also feature onboard controls for attenuation, polarity reversal, and delay up to 4.5 ms in steps of 0 (while maximum delay via Aurora Net is 21 ms). A second rotary dial allows you to adjust the crossover frequency from 70 to 110 Hz.
 The sturdy wooden cabinet has a limited weight (41.8 kg) and is equipped with 2 integrated handles on the upper edges, while the rear panel offers the possibility of mounting a wheel kit for even easier transportation. The sub's design allows for vertical or horizontal use, and for this reason the cabinet is equipped with 2 M20 cups for standard pole located on the top panel and on the side.
