Unleash the power of live sound with the LD Systems Icoa Pro 21 A, a dynamic 3,000-watt powered subwoofer expertly engineered to elevate any live performance. This sub delivers an impressive 136dB maximum SPL through its 21-inch woofer, which features an ultra-strong neodymium motor and a 4.5-inch voice coil for fast, tight response. Furthermore, SysCore DSP ensures distortion-free sound, even at maximum output. It includes two XLR inputs, two XLR-Thru outputs, and a powerCON loop-through connection for seamless integration. Additionally, this state-of-the-art subwoofer offers six application presets, including low-latency and cardioid functions, along with a 4-band EQ and adjustable time delay, while the free app facilitates remote adjustments via your smartphone or tablet. The Icoa Pro 21 A offers easy transport with its eight ergonomic handles, and you can install it quickly using its two M20 threads and stacking grooves. Built to last, the Icoa Pro 21 A features a robust polyurea-coated birch plywood cabinet and a shock-resistant grille.

State-of-the-art SysCore DSP

Thanks to the LD Systems Icoa Pro 21 A’s SysCore DSP, which provides advanced limiters and temperature and voltage monitoring, you can expect distortion-free performance — even at rafter-shaking volumes. The Icoa Pro 21 A also includes six intuitive application presets, including low-latency and cardioid functions, along with a 4-band parametric EQ for fast, user-friendly sound adjustment and adjustable time delay up to 164 feet. When we ran the Icoa Pro 21 A through its paces here at Sweetwater, we were especially impressed with its free app, which allows for remote adjustments via your smartphone or tablet.
