B218 High-Performance Subwoofer | The Ground-Stacking Benchmark for Professional Reinforcement

Core Transducer Architecture: Massive Acoustic Power, Pristine Transient Resolution

B218Integrate dual 18-inch long-excursion transducers co-developed with B&CSpeakers Italy, pairing each driver with a 4-inch voice coil to yield a massive 4000 W music power capacity per transducer.

Ensure long-term mechanical reliability under maximum thermal loading through waterproof cones and triple-roll surround geometry.

Utilize a high-flux neodymium magnet structure and dual-spider suspension to expand linear displacement, sharpening transient response and delivering dynamic, uncompressed sub-bass that accurately resolves low-frequency musical detail.

Arraying Versatility: Cardioid Directivity, Precision Soundfield Control

B218 Build cardioid subwoofer arrays in multiples of three enclosures by physically reversing one cabinet and loading dedicated system DSP cardioid presets.

Control low-frequency directivity actively to reject rearward acoustic radiation, reducing boundary reflections to concentrate sub-bass energy forward into the target audience zone for enhanced soundfield punch and immersion.

Cabinet Architecture: Industrial Durability, Ergonomic Stacking

B218 Construct the cabinet using high-density multi-ply birch plywood to fuse high structural firmness with superior acoustic damping. A tough black PU coating covers the chassis, providing impact resistance for demanding indoor and outdoor setups.

Minimize airflow resistance and port noise using a reinforced front steel grille with oversized perforations, eliminating mechanical vibration noise at extreme SPL to safeguard audio purity.Equip ergonomic handles on the side panels for easy physical handling. Interlock top runners with bottom rubber feet to secure stacked configurations against displacement, while side-mounted rubber feet allow flexible horizontal or vertical placement.

Apply across event centers, theaters, clubs, performing arts halls, lounge bars, and high-end KTVs to power live concerts, electronic parties, and cinematic sound effects.Combine seamlessly with full-range enclosures like RL2、RL4、RX12 under matched factory presets, delivering full-spectrum tonal integrity and an immersive acoustic experience.
