LD System ICOA PRO SUB 21 A 3000W 21" DSP Subwoofer,136dB SPL,29Hz Low-End Power

If you're ready to take your sound reinforcement to a truly professional level-where every beat hits harder, cleaner and deeper-the LD Systems ICOA PRO SUB 21 A is the subwoofer that transforms your entire setup. Designed for those who refuse to compromise, this powerhouse brings arena-grade bass into a cabinet compact enough for touring, club installs, and high-pressure mobile DJ events.

This isn’t just “more bass”-it’s precise, controlled, low-frequency energy that stays tight even when pushed to extremes. The heart of this beast is a custom-engineered 21" neodymium woofer with a massive 4.5" voice coil, delivering incredibly fast response and jaw-dropping punch. Whether you're driving a festival crowd or loading a club dance floor with deep, atmospheric lows, the ICOA PRO SUB 21 A gives you that chest-thumping presence professionals demand.

Powered by a 1500W RMS / 3000W peak Class-D amplifier and capable of hitting 136 dB SPL, this sub delivers enormous headroom-and it stays fully controlled thanks to the cutting-edge Sys Core® DSP with FIR/IIR filters and advanced limiters. The result? Zero distortion, even when you’re rattling the room at 29Hz.

For audio technicians and engineers, the flexibility is unmatched:

• 4-band PEQ, 50m delay, and preset options including cardioid modes
• Three crossover choices (80/100/120Hz)
• Wireless configuration via the ICOA PRO App with Bluetooth 5.1 & TWS
• Seamless linking of multiple subs and tops

Built for the real world, the birch plywood cabinet features polyurea coating, stacking grooves, M20 threads for poles, 8 ergonomic handles, and optional castor board-everything you need to deploy quickly and confidently. And despite housing a 21” woofer, its clever compact design slides perfectly into standard touring vans.

The ICOA PRO SUB 21 A isn’t simply a subwoofer-it’s a statement. A standard-setter. A low-end weapon engineered for professionals who want their sound to dominate the room, the stage, and the crowd.
