The ICOA PRO SUB 21 A combines massive bass performance with a smart and roadworthy design. The 3 kW 21ʺ high-performance subwoofer with bass reflex design delivers huge, accurate and powerful bass range with its specially developed 21ʺ neodymium woofer - ideal for mobile DJs, clubs, live events, festivals and permanent installations.

The centerpiece of the ICOA PRO SUB 21 A is the extremely powerful 21ʺ woofer with a 4.5ʺ neodymium motor. Thanks to its long throw design and precisely tuned suspension, this subwoofer delivers unexpectedly tight, dry and accurate low bass.

The powerful Class D power amplifier delivers up to 1500 W RMS (3000 W peak) and 136 dB max SPL, providing huge reserves and reliable low bass performance. Four extra-large, flow-optimized bass reflex ports provide rich low end down to 29 Hz.

The modern SysCore DSP with FIR/IIR filters and advanced limiters guarantees distortion-free sound and safe operation even at very high volumes.

With 4-band PEQ, delay function (up to 50 m) and three selectable crossover frequencies (80 Hz, 100 Hz and 120 Hz), the subwoofer can be flexibly adapted to different setups. Preconfigured presets are already available for low-latency monitoring and cardioid applications.

You navigate through the intuitive menu via the one-button color screen or the free ICOA PRO app (iOS/Android). All settings can be adjusted quickly and wirelessly via the app, and multiple speakers can be linked together. A stereo setup with up to two tops and four subs, including direct music streaming via Bluetooth 5.1 and TWS, can be created in seconds and ready for use in the app. A status LED on the front of the subwoofer provides easy identification and indicates if the limiter is activated.

Two XLR inputs, two XLR outputs and a powerCON Loop-Thru connection allow for uncomplicated system wiring and flexible expansions.

Integrated stacking cutouts and two M20 flanges allow the subwoofer to be safely stacked horizontally or vertically and flexibly incorporated into any setup.

The 15-18 mm birch plywood cabinet is deliberately kept compact and has the same dimensions as an 18ʺ model. With a width of only 562 mm, the subwoofer fits perfectly into standard vans (Mercedes Sprinter, Fiat Ducato, Ford Transit and VW Crafter) as part of typical transport solutions (Sprinter case/TRANSflex in addition to subwoofer).

This space-saving design, combined with a rugged polyurea coating, makes the ICOA PRO SUB 21 A the ideal choice for touring and installation applications.

Eight ergonomic handles provide a firm grip on all sides and facilitate set-up and tear-down. The optional ICOA PRO SUB CB swivel board makes transport over long distances significantly easier.

The ICOA PRO SUB 21 A sets a new standard with its compact design, powerful low bass performance and state-of-the-art SysCore® DSP. With its impressive "headlining punch" it is the perfect tool for demanding, professional applications such as live events, club installations and mobile DJ setups.
