Our RBN subs are designed to deliver FULL power and deep sound where it matters most. Constructed of heavily braced 18mm birch plywood, the RBN sub is perfect for installations or portable applications where audio quality, reliability and efficiency are of the utmost importance. Incorporating the latest digital signal processing technology, the RBN subwoofers feature two XLR/1/4″” combination inputs, a 3.5mm input, and a mic/line level selection. Each input features digital infrasonic high-pass filters, a 9-band graphic EQ and delay. Each output features a sophisticated compressor/limiter and fourth order highpass/low-pass filters for crossover output. Internal temperature monitors combined with a variable speed cooling fan, plus level and clip indication, ensure reliable performance even during the most demanding conditions. Internal presets built into the DSP allow users to quickly select the speaker’s application via the LCD on the rear of the enclosure.
