### Essential Information About the Wharfedale Delta X218B Passive Subwoofer


- Dual 18-inch high excursion drivers for massive bass reserve and a maximum SPL of 138 dB.
- Flexible wiring: 4-ohm parallel mode or discrete 2 x 8-ohm mode via NL4 connectors.
- Touring construction with "Rhino Rock" coating, 1.5 mm steel grille, and 4 integrated handles.
- 100 dB sensitivity (2.83 V/1 m) and response starting at 30 Hz for live sound, DJ, and installation use.


### Heir to the Delta Series, Redesigned for the Road


Derived from the Delta lineage, the Delta X218B builds on a proven architecture by adding optimized components and a redesigned crossover for increased power handling and reliability. This dual 18-inch model stands as the heavy subwoofer solution in the range, designed for contractors and demanding stages.



### For Whom and Which Venues?


Designed for contractors, clubs, live stages, and DJs, the Delta X218B excels when dense and controlled bass is required. Used alone to reinforce a compact system, or stacked (coupling two or four cabinets per side) for more ambitious shows, it delivers impact and foundation without sacrificing mix clarity.



### Key Features and Acoustic Advantages



#### High-Efficiency Dual 18-Inch Drivers


Its two 18-inch drivers with 4-inch voice coils deliver considerable energy while maintaining a smooth response. The 100 dB sensitivity facilitates use with a wide range of modern amplifiers.



#### Flexible Wiring, Ready for Your Amplifiers


The NL4 terminal allows two modes: parallel for a 4-ohm load (powered by a single powerful channel), or discrete for two 8-ohm loads (separate powering of each speaker). This flexibility simplifies integration into existing amplification racks.



#### Tour-Ready Construction


Its 18 mm cabinet features a highly durable "Rhino Rock" textured coating resistant to shocks and scratches. The 1.5 mm steel grille effectively protects the drivers, while the four side handles facilitate road handling.
