The ICOA PRO SUB 21 A combines massive bass performance with a sophisticated, roadworthy design. The 3 kW 21" This high-performance subwoofer with a 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 heart 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 unexpectedly tight, dry, and precise bass.

The powerful Class D amplifier delivers up to 1500 W RMS (3000 W peak) and 136 dB max. SPL, providing enormous reserves and reliable bass performance. Four extra-large, flow-optimized 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 reliable operation even at extreme levels.

With a 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 various setups. Preconfigured presets are available for low-latency monitoring and cardioid applications.

Intuitive menu navigation is available via the color display with one-knob control or with the free "ICOA PRO" app (iOS/Android). All settings can be adjusted quickly and wirelessly using the app, and multiple speakers can be paired together. A stereo setup with up to two mid-woofers and four subwoofers, including direct music streaming via Bluetooth 5.1 and TWS, can be created and used in the app within seconds. A status LED on the front of the subwoofer allows for easy identification and, if necessary, provides information about limiter intervention.

Two XLR inputs, two XLR outputs, and a powerCON loop-thru connection enable straightforward system cabling and flexible expansion.

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

The cabinet, made of 15–18 mm birch plywood, is deliberately compact and resembles the dimensions of an 18" model. With a width of just 562 mm, the subwoofer fits perfectly into common 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 PRO SUB 21 A the ideal choice for touring and installation.

Eight ergonomic carrying handles provide optimal grip from all sides and facilitate setup and dismantling. Transport over longer distances is made considerably easier with the optional ICOA PRO SUB CB dolly.

Thanks to its compact design, powerful low-frequency performance, and state-of-the-art SysCore® technology, the ICOA PRO SUB 21 A is ideal for use in commercial vehicles. The ICOA PRO SUB 21 A sets new standards in 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.
