The VIO S118R is an active bass reflex subwoofer designed to complement the VIO line array systems (L208 and L210) in the low frequencies. Unlike the horn-loaded S118, the S118R utilizes a bass reflex configuration to deliver a deep, warm, and extended low-end response down to 32 Hz, making it perfect for applications requiring impactful sub-bass.
Equipped with a premium 18" neodymium woofer with a 4" voice coil. The bass reflex cabinet design ensures efficient air movement for a punchy response. It also features a dedicated Cardioid Preset button on the rear panel, automatically processing the sound for inverted stack configurations to cancel rear output.
Powered by a massive 1600W RMS Digipro G4 Class-D amplifier with Power Factor Correction (PFC) for stability against voltage fluctuations. Advanced features include:
| Max SPL | 139 dB |
| Frequency Response (-10dB) | 32 Hz |
| Controller / AD/DA | DSP 32 bit | 24 bit/96 kHz |
| Dimensions (WxHxD) | 720 x 520 x 695 mm |
