Description.
Add depth and impact to your PA system with the Montarbo R15S active subwoofer. Designed to complement Montarbo B and R Series loudspeakers, this 15-inch subwoofer reinforces the low frequencies that smaller full-range speakers can struggle to reproduce, giving music and live performances a fuller, more powerful sound. It's a great choice for DJs, bands, mobile entertainers and venues looking to build a capable sound system without unnecessary complexity.
The R15S combines a 15-inch low-frequency driver with a 4-inch voice coil and 500W RMS amplification, reaching a maximum SPL of 130dB. Its frequency response extends down to 45Hz at -10dB, providing a solid bass foundation for dance music, live instruments and general sound reinforcement. A Class D amplifier and passive cooling design help keep the system efficient and practical for extended use.
Built-in DSP gives you useful control over how the subwoofer integrates with your main speakers. You can adjust the level, select the crossover frequency and switch polarity to help achieve a more balanced system. Stereo inputs allow you to connect both left and right signals directly, while the LINK/XOVER output can route the signal to your main speakers or link another subwoofer, reducing the need for additional processing equipment in straightforward setups.
The R15S is housed in a sturdy multilayer wooden cabinet with a protective polyurea finish, making it suitable for regular transport and professional use. An integrated M20 pole mount allows a full-range speaker to be positioned above the subwoofer, while the side handles make handling more manageable. For anyone looking to add powerful, controlled bass to a portable PA system, the Montarbo R15S is a practical solution for live sound, DJ setups and small to medium-sized venues.
A good PA system needs a solid low-frequency foundation, and that's exactly where the Montarbo R15S comes in. This 15-inch active subwoofer adds depth and impact to your sound system, taking the pressure off your full-range speakers and giving music and live performances more weight. We particularly like the wooden cabinet construction shared across the R-Series, offering a robust, professional finish that's built for life on the road as well as regular installation use. It's a great addition for DJs, bands and venues looking to get more out of their PA system.
