Some speakers can get loud, but real music lives in the bass. The LD ICOA 18A is a powered 18" subwoofer built to make your set hit harder, cleaner, and deeper. With 2400 watts of Class D power, it doesn’t just add boom; it frees up your mains, giving you more headroom and clarity across the entire mix. Whether you’re pushing a band, a DJ rig, or a multimedia event, this LD subwoofer 18A brings the chest-thumping presence that turns sound into an experience.
The LD ICOA 18A gives you both raw power and the control to shape it to the room. Its DSP presets, crossover options, and cardioid mode let you dial in everything from chest-thumping club sound to subtle reinforcement for a conference.
With this kind of versatility, the LD ICOA 18A isn’t just a subwoofer; it’s the foundation that makes your whole mix sound tighter, clearer, and more powerful.
The LD subwoofer 18A was built for the road, with a housing tough enough for touring and features that make setup simple. From stacking grooves, every detail is designed to get you in and out of gigs without slowing you down.
The ICOA SUB18A is equally at home in clubs, on tour, or in permanent installs: always ready to rumble, never overcomplicated.
If your shows need more punch, more depth, and more presence, the LD ICOA 18A is the sub that brings it. Add one to a small system for instant authority, or scale up with multiple subs in cardioid arrays to control the room’s low end. However you run it, it’s the piece of gear that makes your whole system sound pro.
