VTX B18 是 JBL Professional 推出的下一代单只 18" 低频扬声器，专为搭配 VTX 全频段扩声系统而设计。VTX B18 采用 JBL 新型 2288H 18" 低频单元，具有改进的线性响应、更高的灵敏度和超长冲程。2288H 基于 JBL 的差动驱动双音圈双气隙技术，相比传统单音圈设计，具有更好的散热性能、更低的功率压缩和更宽的动态范围。B18 配备 JBL 获专利的 Slip Stream™ 双喇叭口指数型低频导向孔设计，可改善气流并降低可闻噪声，即使在最大冲程时也不例外。VTX B18 采用与 JBL VTX A 系列产品相同的工业设计，宽度和悬挂硬件与 VTX A8 相同，允许两款产品在各种吊挂或堆放配置中配合使用。VTX B18 可部署在全向或心形指向配置中，支持多达 16 只音箱的阵列组合。
