B 18 WP
B 18 WP is a weatherised passive subwoofer engineered for permanent outdoor installations where reliable low‑frequency qualitiy and long‑term protection are essential. Pairing marine‑grade construction with an IP‑rated design and installer‑friendly mechanics, it delivers deep, controlled bass and integrates seamlessly with SE outdoor systems such as M3 MAX WP.
- All‑weather passive subwoofer engineered for outdoor use (IP 55 rating)
- Marine‑grade enclosure with durable coatings and multi‑layer protective grille
- Flexible deployment: stackable or flyable with dedicated accessories; secure on‑ground options
- Seamless system integration with SE weatherised tops and amplifier presets for fast, consistent results
- Available in black and white
Purpose‑built for open‑air venues, B 18 WP brings SE low‑frequency performance to environments where the weather is part of the brief. Its outdoor‑grade enclosure, protective grille architecture, and water‑smart porting work together to resist dust, rain, and spray while maintaining clean airflow and consistent acoustic behaviour. A robust driver and carefully tuned vented system deliver deep, musical low end with reduced artefacts around tuning, ensuring impact without muddiness.
Integration is straightforward. Dedicated amplifier presets simplify protection and voicing, while the cabinet’s clean industrial design and compact footprint help it blend into architectural surroundings. Connectivity is routed through a weather‑resistant rear panel with sealed cable entry for dependable operation season after season.
For system designers, the B 18 WP supports both stacked and flown configurations via accessories, with provisions that keep ground stacks secure and stable. It partners naturally with M3 MAX WP and other weatherised SE loudspeakers, enabling both straightforward reinforcement and directional low‑frequency arrays. From theme parks and cultural‑tourism theatres to plazas, resort spaces, and open‑air stages, B 18 WP provides even, confident bass coverage with the resilience outdoor installs demand.
