21" Powered Pro-Sound Subwoofer | 1500W RMS | Bluetooth 5.1 receiver | Massive bass performance | Clever & roadworthy design | Wireless App control | SysCore DSP with FIR/IIR filters | 2 x mic/line inputs | 2 x line outputs | 'Truewireless' Stereo

The ICOA PRO SUB 21 A is a 21ʺ high-performance subwoofer with bass reflex design and Bluetooth, delivering a massive, precise and powerful bass range with its specially developed 21ʺ neodymium woofer − ideal for mobile DJs, clubs, live events, festivals and permanent installations.

The ICOA PRO SUB 21A subwoofer boasts an extremely powerful 21ʺ woofer with a 4.5ʺ neodymium motor. The long-throw design and precisely tuned suspension unexpectedly delivers a tight, dry and precise low bass.

The powerful Class D power amplifier delivers up to 1500 W RMS (3000 W peak) and 136 dB max. SPL, providing 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 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.

An intuitive menu is navigated using the colour display with one-knob control. Alternatively, the free ICOA PRO app enables all settings to be adjusted quickly and wirelessly, 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 created 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 indicates if the limiter is activated.

Two XLR inputs, two XLR outputs and a powerCON Loop-Thru connection enable simple system cabling and flexible expansions.

Integrated stacking recesses and two M20 flanges enable this Pro Sub to be safely stacked horizontally or vertically and flexibly built into any setup.

The compact 15−18 mm birch plywood cabinet has been thoughtfully designed with a width of just 562 mm, to fit 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, combined with a robust polyurea coating, makes the ICOA PROSUB21A the ideal choice for touring and installation applications.

Eight ergonomic carrying handles provide a secure grip on all sides and facilitate setup and dismantling. The optional ICOA PRO SUB CB castor board makes long-distance transport considerably easier.

The ICOA PRO SUB 21 A sets new standards 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.
