Samson SARS1800A 18" Active Subwoofer

High-Powered Subwoofer for Live Sound and Fixed Installations
The Samson RS1800A is a professional-grade 1000-watt active subwoofer featuring an 18-inch woofer with a 4.5-inch voice coil. Designed for mobile DJs, live performers, and venues that demand tight, extended low-end response, this subwoofer integrates easily into existing PA systems and enhances the low-frequency performance of any audio setup. Whether you're building a portable rig or outfitting a permanent space, the RS1800A delivers clarity and power exactly where it counts.

Massive Low-End with Precision and Control
The RS1800A is equipped with a high-output 18-inch woofer that’s driven by a powerful Class D amplifier. Its large voice coil ensures detailed response across the sub-bass range, providing the kind of deep, resonant sound that fills dance floors, concert halls, and houses of worship. The frequency range and dynamic headroom make this an ideal choice for sound professionals who want to reinforce the bottom end without distortion or muddiness.

Clean Audio Routing with Professional I/O Options
To meet the routing needs of modern sound systems, the RS1800A offers balanced stereo XLR inputs, balanced XLR full-range outputs, and stereo high-pass outputs. These allow seamless integration with satellite speakers, mixers, or additional subwoofers. The high-pass outputs filter out the low frequencies sent to top cabinets, preserving their clarity while the subwoofer handles the heavy lifting.

Adjustable Audio Tuning for Any Room or Setup
With a variable crossover control and a polarity switch, the RS1800A lets users tailor the output to match the acoustic characteristics of the room and align with the rest of their system. Fine-tune your frequency response for everything from punchy live band performances to immersive theater sound. These flexible settings make the RS1800A easy to configure whether you're touring or setting up in a fixed location.

Road-Ready Design with Long-Term Durability
Built to withstand the rigors of constant use, the RS1800A features a robust wooden cabinet with internal bracing and a protective epoxy coating. It also includes a standard 1 3/8" pole mount socket, allowing you to securely mount a top speaker for a clean, space-saving setup. The cabinet’s structure ensures focused sound projection while remaining rugged enough for transport.

Built for DJs, Worship Leaders, Installers, and Engineers
Whether you're running sound for a large church, mixing a club show, or building a mobile DJ system, the RS1800A subwoofer provides the bass you need to get the job done. It adds serious depth and dynamic impact to your mix, helping you bring out the full potential of your audio system without compromises.
