LD Systems ICOA 15A 15" 300W Active PA Speaker

Versatile 15" 300W RMS Active Coaxial PA Speaker With Horn-Loaded Woofer, Rotating BEM-Optimised CD Horn & DynX DSP For Full-Range, Satellite & Monitor Applications – LD Systems ICOA 15A.

The LD Systems ICOA 15A is a professional 15" active coaxial PA speaker delivering 300W RMS (1,200W peak) and 128dB maximum SPL, designed as a genuine all-rounder for full-range, satellite and floor monitor applications across live music, DJ, entertainment and dance school environments. The coaxial driver design combines a 15" horn-loaded woofer with a 1" HF driver and a large rotating BEM-optimised CD horn, providing consistent 90° x 50° dispersion in any orientation — deployable vertically as a main PA or satellite speaker, horizontally in suspended systems, or at 55° as a floor monitor without any compromise to the dispersion characteristics. The horn-loaded woofer delivers outstanding bass reproduction extending down to 48Hz, allowing DJs to perform full sets without the need for a separate subwoofer.

DynX DSP provides four application presets, a 3-band EQ and a delay function for precise sound optimisation to any venue environment, accessible via a rotary encoder and LC display on the rear panel. Two combo XLR/6.3mm jack mic/line inputs with individual gain controls and a 3.5mm TRS line input provide flexible source connectivity, and an XLR mono mix output allows signal pass-through to additional speakers. A 36mm dual-tilt stand attachment with selectable 0° and 5° tilt angle and six M10 flying points provide comprehensive mounting options for any installation or live performance scenario, and the shock-resistant front grille and four ergonomic aluminium handles with rubber grips ensure practical durability and safe handling during regular transport and setup.

Coaxial Design With Horn-Loaded Woofer & Rotating BEM Horn

The ICOA 15A’s coaxial driver configuration places the 1" HF driver concentrically within the 15" woofer, with both drivers sharing the BEM-optimised rotating CD horn for consistent point-source dispersion across the full 90° x 50° coverage pattern. The horn loading of the woofer provides exceptional bass efficiency and extension down to 48Hz — delivering the kind of full-range low-end performance that makes the ICOA 15A capable of covering DJ and live music applications without the need for additional subwoofer support. The rotating horn allows the cabinet to be repositioned vertically or horizontally while maintaining optimal dispersion orientation.

DynX DSP – 4 Presets, 3-Band EQ & Delay

DynX DSP provides comprehensive on-board signal processing for precise performance optimisation in any acoustic environment. Four application presets cover the most common deployment scenarios for fast and confident setup, a 3-band EQ allows fine tonal adjustment to suit different venues and source material, and a delay function enables accurate time alignment in multi-speaker configurations. All controls are accessed via the intuitive rotary encoder and LC display, providing a straightforward and professional operator interface in demanding live and installation environments.

Flexible Deployment & Robust Construction

The ICOA 15A is designed for genuinely flexible deployment across a wide range of applications. The 55° monitor angle provides an ideal floor monitor position with the shock-resistant grille protecting the drivers from stage-level impact, the 36mm dual-tilt stand flange with 0° and 5° tilt accommodates different acoustic environments when pole-mounted, and six M10 flying points enable secure and professional hanging installation. The polypropylene cabinet is lightweight yet durable, and four aluminium handles with ergonomic rubber grips provide safe and secure carrying during setup and breakdown.
