Description.
For sound systems that need serious low-frequency impact, the Montarbo R18S is an 18-inch active subwoofer designed to add depth and authority to live performances, DJ sets and professional PA installations. Built to complement Montarbo B and R Series loudspeakers, it strengthens the bass response of your system, giving music greater weight and helping live sound feel fuller and more engaging.
The R18S combines an 18-inch low-frequency driver with a 4-inch voice coil and 500W RMS amplification, with 1,000W peak power. Reaching a maximum SPL of 131.5dB and extending down to 41Hz at -10dB, it provides the low-end performance needed for bass-heavy music and demanding live applications. Its Class D amplifier platform and passive cooling design are well suited to regular professional use.
Onboard DSP makes it easier to integrate the R18S with your main speakers, with adjustable level, crossover frequency and polarity controls. Stereo inputs allow you to connect left and right audio signals directly, while the LINK/XOVER output can either pass the signal on or route it through the subwoofer's crossover to your full-range speakers. This flexibility helps simplify system setup without requiring a separate external crossover for straightforward configurations.
A robust multilayer wooden enclosure with a durable polyurea finish is built to withstand the demands of mobile sound reinforcement. The cabinet includes side handles and an M20 pole mount for positioning a full-range speaker above the subwoofer. Weighing 38kg, it offers substantial bass performance in a practical professional enclosure. For DJs, bands and venues looking to add powerful 18-inch bass reinforcement to a portable PA system, the Montarbo R18S is a capable choice.
For setups that demand serious low-frequency performance, the Montarbo R18S is a worthy addition to the system. Its 18-inch driver brings plenty of depth and impact to music, making it an excellent choice for DJs, live bands and venues looking to build a more powerful PA system. As with the rest of the R-Series, the wooden cabinet is a big plus for us, providing a tough, professional enclosure designed to handle the demands of regular use. Pair it with the R-Series full-range speakers and you've got the foundations of a capable, well-rounded sound system.
