A flyable active subwoofer, equipped with a 18” neodymium woofer and crafted to complete with impressive low-end frequencies and vigorous SPL VIO L210’s accurate, phase coherent wave front.dBTechnologies developed a horn loaded design, while maintaining the size of a front-loaded sub cabinet, resulting in a double advantage: smaller dimension (and weight – only 45,1 kg) and a remarkable lower frequencies response even at a long distance.This makes this sub the perfect low-end extension of VIO arrays whenever a particularly long-throw is needed.The system’s acoustical plus points are boosted by Digipro G4® 1600W Class D amplifier, the last generation of the Digipro amp technology which strongly contributed to the success of many dBTechnologies’ professional powered series. Equipped with PFC (Power Factor Correction) and SMPS , VIO S118 is highly resistant to line voltage fluctuations.Digipro G4 pre-amp features a slot module allowing system monitoring and control via RD Net. Furthermore, the system is ready for future upgrades with DanteTM digital audio transmission network: in facts, VIO S118 also features a NFC system and a LED on the front grille.
