BASSBOSS DJ18S-MK3 18" Powered Subwoofer

When deep, physical bass is non-negotiable, the BASSBOSS DJ18S-MK3 delivers club-level impact from a surprisingly compact enclosure. Designed around a long-excursion 18" neodymium woofer with a massive 4.5" copper-wound voice coil and powered by a 2500W Class-D amplifier, this premium powered subwoofer reaches down to 27Hz (±3dB) with authority. Producing up to 132dB peak SPL (half-space, 1m), it’s engineered for modern music styles that demand energy well below the typical 50–100Hz range. Despite its output capability, the DJ18S-MK3 weighs just 110 lb., making it easier to deploy than many traditional high-output sub systems. From large DJ events and touring rigs to high-impact club installations, this active subwoofer is built to move serious air without requiring serious heavy lifting.

High-Output 18” Design With Advanced Amplification

At the core of the DJ18S-MK3 is a vented, direct-radiating enclosure tuned for high sensitivity at extremely low frequencies. The neodymium motor structure increases efficiency while reducing weight, allowing the system to deliver greater output than comparable ferrite-based designs. Its 2500W amplifier features a globally compatible auto-sensing power supply (100–240V AC), with full output available above 110V. High peak-output voltage delivers strong transient impact, while sustained output remains smooth and controlled for demanding sub-bass passages. Passive cooling through an external heat sink and airflow from the port minimizes noise, while dual blower fans engage only when needed to maintain thermal stability in high-output environments.

Intelligent DSP With Comprehensive Protection

The all-new MK3 DSP platform operates at a 96kHz sampling rate and integrates high-pass and low-pass filters, phase alignment, equalization and multi-stage limiting. Five levels of protection monitor thermal load, excursion, clipping and long-term compression to help prevent driver damage without compromising transient response. Up to 100 presets can be stored internally, with eight accessible directly from the rear-panel pushbuttons for quick recall without a connected computer. The Ethernet interface enables connection to ControlBASS software, where multiple cabinets can be grouped for coordinated level control, preset management and real-time monitoring of signal levels and temperature. Each cabinet includes a two-port EtherCON switch, allowing simple daisy-chaining across a single network line.

Built for Outdoor and Touring Reliability

The MK3 introduces Neutrik powerCON True1 TOP IP65-rated waterproof power connectors for secure, weather-resistant operation. Waterproofed cones, a fully isolated input section and rugged construction support reliable performance both outdoors and indoors. The CNC-machined 18 mm birch plywood cabinet features extensive internal bracing and dado joinery for maximum structural integrity. A high-pressure bonded polyurea coating protects the enclosure with a rugged, waterproof textured finish, while a perforated powder-coated steel grille safeguards the driver. Integrated handles, a 35 mm pole socket, rubber feet and included locking 4" swivel casters make transport and deployment straightforward in real-world production environments.

Seamless System Integration and Phase-Coherent Performance

As part of the BASSBOSS ecosystem, the DJ18S-MK3 integrates seamlessly with the company's tops and additional subwoofers. Any BASSBOSS powered sub can be combined with another BASSBOSS sub, and outputs will sum coherently for phase-aligned reinforcement. Likewise, any BASSBOSS powered sub and powered top combination will maintain phase coherence through the crossover region when physically aligned. This ensures consistent frequency response without cancellations or gaps, regardless of preset selection. Setup is streamlined because cabinet, transducer, amplifier and processing are engineered as a unified system.

Deep Bass, Smart Control and Professional Confidence

With output down to 27Hz, 2500W of clean amplification, advanced DSP management and rugged IP65-rated power connectivity, the DJ18S-MK3 stands as a purpose-built solution for bass-intensive applications. It delivers the punch and depth required for modern electronic music while maintaining the precision and reliability demanded by professional touring and installation environments. Whether deployed as a standalone sub or as part of a larger BASSBOSS system, it provides powerful, coherent low-frequency reinforcement with intelligent control options. For those who demand authoritative extended low end without compromise, the DJ18S-MK3 subwoofer delivers serious performance in a compact, road-ready format.
