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.
Power and Control for Every Performance
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.
2400W Class D amplifier with 133 dB max SPL
18" bass reflex driver reaching down to 29 Hz.
DynX DSP with 4 presets (3 crossover frequencies plus cardioid)
Adjustable delay line up to 10 meters for larger setups
Switchable polarity for flexible system alignment
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.
Rugged Design, Seamless Integration
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.
18 mm laminated plywood cabinet with protective corners
Four ergonomic aluminum handles with rubber grips
Stackable design with built-in grooves for stable setups
M20 pole mount for flying your mains above the sub
Dual combo inputs + XLR outputs for flexible connectivity

The ICOA SUB18A is equally at home in clubs, on tour, or in permanent installs: always ready to rumble, never overcomplicated.
Bring the Thunder with the LD ICOA 18A
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.
