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

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

The powerful Class D power amplifier delivers up to 1500 W RMS (3000 W peak), 136 dB max. SPL and therefore enormous reserves and reliable low bass performance. Four extra-large, flow-optimised bass reflex ports ensure a 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 extreme levels.

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

The intuitive menu navigation is carried out via the colour display with one-knob control or with the free "ICOA PRO" app (iOS/Android). All settings can be adjusted quickly and wirelessly via the app and multiple speakers can be paired with each other. A stereo setup with up to two tops and four subs, including direct music streaming via Bluetooth 5.1 and TWS, can be set up and ready for use in the app in just a few seconds. A status LED on the front of the subwoofer enables easy identification and provides information on the intervention of the limiter if required.

Two XLR inputs, two XLR outputs and a powerCON loop thru connection enable uncomplicated system cabling and flexible expansions.

Thanks to the integrated stacking recesses and two M20 flanges, the subwoofer can be safely stacked horizontally or vertically and flexibly integrated.

The 15-18 mm birch plywood enclosure is deliberately compact and resembles the dimensions of an 18" model. With a width of just 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 next to subwoofer).

This space-saving design in combination with a robust polyurea coating makes the ICOA PRO SUB 21 A the ideal choice for touring and installation operations.

Eight ergonomic carrying handles provide optimum support from all sides and facilitate assembly and disassembly. Transport over longer distances is made considerably easier by the optional ICOA PRO SUB CB trolley.

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