(dB Tech ViO-X315)
15-Inch 3-Way Powered PA Speaker
The dBTechnologies VIO X315 is a high-output 3-way powered PA speaker designed for professional touring, concerts, live sound reinforcement, and fixed installations. Featuring a 15-inch neodymium woofer, a coaxial mid/high-frequency compression driver, and a 1400W RMS Digipro G4 Class-D amplifier, it delivers up to 137dB maximum SPL with a frequency response of 37Hz to 18kHz (-6dB). Its advanced FIR DSP processing, 90° x 50° controlled coverage, RDNet network connectivity, and versatile mounting options provide precise sound reproduction for standalone PA systems, high-output fill speakers, and professional sound installations.
dBTechnologies VIO X315 Competitive Differences

dBTechnologies VIO X315 Description
The dBTechnologies VIO X315 combines a true 3-way acoustic design with high-output amplification to deliver powerful, full-range sound reinforcement from a single active loudspeaker. Its 15-inch neodymium woofer features a 4-inch voice coil for strong, controlled low-frequency reproduction, while the coaxial mid/high-frequency compression driver uses separate 4-inch and 2.5-inch voice coils with a 1.4-inch high-frequency exit. This configuration reproduces critical midrange and high-frequency content with precision, making the speaker particularly effective for vocal intelligibility, instrument separation, and detailed musical performances. With a frequency response of 37Hz to 18kHz (-6dB) and up to 137dB maximum SPL, the VIO X315 offers substantial full-range output for professional audio systems.
The speaker's coaxial mid/high-frequency assembly is positioned behind a rotatable 90° x 50° horn designed with approximately 5° of downward acoustic tilt. This configuration provides controlled sound dispersion and helps direct acoustic energy toward the audience, reducing unnecessary sound spread into surrounding surfaces. The horn-loaded mid/high-frequency section improves acoustic efficiency and directivity across the critical vocal and instrumental frequency ranges. Its combination of coaxial transducers and controlled horn coverage provides consistent sound imaging for front-of-house applications, fill speakers, and distributed sound reinforcement.
Powering the VIO X315 is a 1400W RMS Digipro G4 Class-D amplifier with four amplification channels and dedicated DSP processing for the individual speaker components. A 32-bit digital controller and 24-bit/96kHz AD/DA conversion work with linear-phase FIR filters to optimize the system's frequency and phase response. The full-range switch-mode power supply incorporates Power Factor Correction (PFC) to support stable operation across varying mains conditions. Passive convection cooling eliminates the need for an amplifier cooling fan, while peak, RMS, and thermal limiting provide protection during demanding performances.
Integrated RDNet connectivity allows detailed remote control and monitoring through dBTechnologies Aurora Net software. Users can monitor amplifier conditions, adjust input attenuation, configure high-pass filters, apply equalization, manage individual speaker components, and store system presets. Advanced processing provides access to delay settings up to 560ms and up to 16 EQ filters for accurate alignment and venue-specific tuning. An onboard System Test function checks transducer operation, while the front identification LED helps technicians locate individual loudspeakers in larger installations. The rear panel also includes a USB service connection for firmware updates and a modular expansion slot supporting optional digital audio networking upgrades.
Built for touring and permanent installation, the VIO X315 features a rugged black wooden enclosure with three integrated carrying handles, twelve M10 threaded rigging points, and a 36mm pole-mount socket. Balanced XLR input and link connections simplify audio distribution, while PowerCON TRUE1 input and output connectors support power linking between compatible loudspeakers. The speaker can be used as a standalone full-range PA, a high-output front-fill or side-fill cabinet, an under-balcony loudspeaker, or part of a distributed delay system. Its combination of extended bass response, controlled directivity, advanced DSP, and flexible mounting makes it suitable for concerts, outdoor events, theaters, auditoriums, and professional sound reinforcement installations.
