A 21-Inch Driver That Redefines Compactness on the Road
Designed for tours and rental companies, the ICOA PRO SUB 21 A combines impactful infrasonic bass with a compact footprint. Its 15-18 mm birch plywood cabinet with a rugged textured finish withstands intensive use. At only 562 mm wide, it easily fits into the most common vans and stacks securely both horizontally and vertically thanks to molded stacking grooves.
Who Is It For and What Are Its Uses?
Ideal for mobile DJs, clubs, live stages, festivals, and fixed installations, this 21-inch subwoofer delivers a spectacular foundation while maintaining precise and fast response. Dedicated presets, including a cardioid mode, facilitate integration in stereo setups or subwoofer arrays, ensuring consistent low-frequency control in rooms of various sizes.
DSP, Control, and Simplified Integration
At the heart of the system, the SysCore DSP ensures clean sound protected by advanced limiters and thermal/electrical monitoring. The 4-band parametric equalizer and delay up to 50 m allow precise alignment of the subwoofer with any system. Three switchable crossover frequencies (80/100/120 Hz) optimize coupling with your tops. The user interface combines a color screen with a single encoder and the free "ICOA PRO" app (iOS/Android) for wireless control, networking multiple speakers, and quick creation of stereo configurations (up to two tops and four subs), with music streaming management via Bluetooth 5.1 and TWS. The front LED facilitates quick identification and limiter status at a glance.
On the connectivity side, two XLR inputs, two XLR-THRU outputs, and a PowerCON Loop-Thru mains output speed up cabling and system expansion.
