Call For Price
The dBTechnologies VIO S118 is a professional 18-inch flyable powered subwoofer designed for touring sound systems, concerts, live events, and large-scale sound reinforcement. Featuring a 1600W RMS Digipro G4 Class-D amplifier, an 18-inch neodymium woofer with a 4-inch voice coil, and up to 139dB maximum SPL, it delivers powerful low-frequency output from a compact horn-loaded enclosure. Its integrated rigging hardware, RDNet network control, onboard cardioid processing, and adjustable DSP settings make it a versatile bass extension for VIO line array systems in both flown and ground-stacked configurations.
The dBTechnologies VIO S118 provides high-output low-frequency reinforcement for professional sound systems requiring powerful bass projection and flexible deployment. Its horn-loaded acoustic design combines an 18-inch neodymium woofer with a 4-inch voice coil and a powerful Digipro G4 Class-D amplifier rated at 1600W RMS and 3200W peak. Capable of producing up to 139dB maximum SPL, the subwoofer offers a usable frequency response beginning at 39Hz (-6dB), with the upper frequency limit determined by the selected crossover setting. Its horn-loaded configuration provides efficient low-frequency projection while maintaining a comparatively compact cabinet footprint.
The integrated Digipro G4 amplifier incorporates a switch-mode power supply with Power Factor Correction to maintain consistent performance under varying electrical conditions. A 32-bit DSP processor and 24-bit/96kHz AD/DA conversion provide precise control of system parameters. Rear-panel controls include input attenuation, selectable crossover frequencies from 60Hz to 110Hz, polarity inversion, and adjustable delay from 0 to 9.9ms in 0.1ms steps. An onboard cardioid preset allows the subwoofer to be incorporated into suitable directional bass arrays, while RMS, peak, and thermal limiting provide protection during high-output operation.
Network connectivity expands the VIO S118's functionality in complex professional sound systems. The factory-installed RDNet expansion card enables remote monitoring and control of amplifier and DSP parameters through compatible dBTechnologies software and network interfaces. Users can monitor system status, adjust settings, and perform diagnostics across multiple connected loudspeakers. The modular expansion slot also supports optional upgrades for Dante digital audio networking. An integrated NFC positioning system and front-grille identification LED help technicians identify individual modules during system configuration. The built-in system self-test provides a convenient way to check the electronics and transducer before and after performances.
Designed for both flown and ground-stacked applications, the VIO S118 features integrated rigging points that allow multiple subwoofers to be assembled into compatible array configurations. The system can be deployed with VIO L210 line array loudspeakers using dedicated rigging accessories, including the DRK-210 flybar and compatible FSA-VIO L210 or GSA VIO L210 adapters. These configurations provide flexibility for venue layouts requiring suspended bass arrays, stacked speaker systems, or cardioid subwoofer arrangements. Dedicated rigging components are required and must be selected according to the intended installation.
The cabinet is constructed from durable Multiplex plywood and finished with a black polyurea protective coating for resistance to wear during touring and frequent transportation. Four integrated aluminum carry handles, two on each side, facilitate handling, while an M20 threaded pole mount supports compatible speaker-pole applications. PowerCON TRUE1 input and output connectors allow power linking between compatible devices, and balanced XLR input and output connections simplify audio signal distribution. An included rear amplifier rain cover provides additional protection in challenging operating environments. With its high SPL capability, advanced processing, and modular rigging design, the VIO S118 is suited for concerts, festivals, touring productions, rental systems, and professional line array installations.
