LD System ICOA PRO SUB 21 A 3000W 21" DSP Subwoofer,136dB SPL,29Hz Low-End Power
The ICOA PRO SUB 21 A combines massive bass performance with a clever and roadworthy design. The 3 kW 21ʺ high-performance subwoofer with bass reflex design delivers 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 centerpiece of the ICOA PRO SUB 21 A is its extremely powerful 21ʺ woofer with a 4.5ʺ neodymium motor. Thanks to its long-throw design and precisely tuned suspension, this 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) and 136 dB max. SPL, providing enormous reserves and reliable low bass performance. Four extra-large, flow-optimized bass reflex ports ensure a rich low end down to 29 Hz.
The modern Sys Core 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.
The intuitive menu is navigated using the color display with one-knob control or 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 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 power CON 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 built into any setup.
The 15−18 mm birch plywood cabinet has been deliberately kept compact and has similar dimensions to an 18ʺ model. With a width of just 562 mm, the subwoofer fits perfectly into standard vans (Mercedes Sprinter, Fiat Ducat, Ford Transit and VW Crafter) as part of typical transport solutions (Sprinter case/TRANS flex 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 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 Sys Core® 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.
