Description
Compact authority with design intelligence—the CELTO IWAC118S packs serious low-end punch in a lightweight, high-output bass reflex design optimized for the IWAC series.
This versatile subwoofer complements IWAC210 arrays in touring, installations, theatres, clubs, and multifunctional venues needing tight, musical bass extension.
Real power handling with premium 18" driver delivers clean reproduction down to the low 30s Hz with impressive efficiency.
Integrated rigging allows flown or ground-stacked configurations, including mixed arrays with IWAC210 for seamless system integration.
Heavily braced Baltic birch plywood cabinet with PolyUrea finish ensures vibration-free performance and touring durability.
Flexible connector layout and preset options support cardioid, end-fired, or standard deployments for controlled directivity.
Easy stacking and transport features make it ideal for rental companies and mobile productions.
