Montarbo R18S – 18″ Active Wooden Subwoofer

The Montarbo R18S active subwoofers combine the rugged, stylish enclosures of their full-range counterparts with high-performance audio design. An M20 threaded pole mount allows for fast and secure installation.

Both models feature stereo inputs and a built-in crossover output, making them ideal for plug-and-play applications. For instance, in a PA setup with one sub and two top speakers, no external processor is required: feed the sub both left and right signals, then split the output directly via the onboard crossover. Additionally, the LINK output can provide a full-range signal to another subwoofer when needed.
