Dual 18-inch Subwoofer Speaker is a high-power, passive low-frequency reinforcement system engineered for large-scale applications requiring extreme bass depth, high output, and unparalleled energy delivery. With dual 18-inch drivers and optimized acoustics, it dominates sub-bass reproduction for immersive audio experiences in professional environments.
Key Specifications & Features:
Dual 18-inch Drivers: Two 18" high-excursion LF units (4Ω impedance) generate massive air displacement, delivering ground-shaking bass from 28Hz to 400Hz (±3dB).
High-Output Performance: 1200W continuous power (2400W peak) and 107dB sensitivity achieve a crushing 135dB peak SPL @1m, ideal for high-energy sound reinforcement.
Industrial-Grade Build:
18mm High-Density Plywood Cabinet: Minimizes resonance and distortion while ensuring structural integrity.- Damping & Absorption: High-density fire-resistant acoustic foam suppresses internal reflections for clean, punchy bass.
- Durable Finish: Textured water-based black coating resists scratches and wear in demanding environments.
Pro Connectivity: Dual NL4 connectors enable parallel wiring for multi-cabinet arrays, simplifying large-system integration.
Portability: Compact design (dimensions not specified*) and optimized weight balance facilitate transport despite its powerful output.
Applications:
Large Outdoor Events & Festivals: Command sub-bass across massive crowds with unparalleled SPL and ultra-low extension.
Nightclubs & EDM Venues: Drive relentless bass energy for electronic music, hip-hop, and high-energy performances.
Cinema & Theater Systems: Enhance blockbuster soundtracks with seismic low-frequency effects (LFE) and precise transient response.
Stadiums & Arenas: Deploy as part of a distributed bass array for uniform coverage in expansive spaces.
Tour Sound & Mobile Rigs: Robust construction withstands rigorous touring while delivering consistent performance.
