Description
The Montarbo R Series includes four full-range wooden cabinets from 8″ to 15″, along with dedicated 15″ and 18″ active subwoofers. Designed for professional audio applications, the R Series delivers powerful sound pressure levels with exceptional clarity, particularly in the vocal range. Advanced FIR filter processing ensures linear phase response and precise, transparent sound reproduction.
Each full-range cabinet features four easily selectable EQ presets, offering flexibility for a variety of applications—including use as stage wedges. The system includes two input channels with independent level controls: one mic/line combo input and an additional line input. A switch on the output channel allows users to choose between a direct link signal or a mixed output from both channels.
The enclosures are built from multilayer wood with a durable polyurea finish. Their clean, modern design is complemented by flush-mounted aluminum side handles, combining professional aesthetics with practical portability.
