The LD Systems ICOA SUB 18 A active subwoofer pumps out serious bass whilst creating greater headroom and a clearer sound by relieving the burden of high-energy bass impulses from the main speaker. This results in less intermodulation distortion. Even at higher volumes, the sound doesn't get muffled. Voices and instruments stay crystal clear.

The built-in powerful Class D amplifier with 600-watt RMS 2400-watt peak) output has integrated DynX DSP presets. Crossover frequencies of 80, 100 and 120 Hz let you finely balance your ICOA SUB perfectly with your system. Signal polarity can also be reversed and the SUB offers a delay line-preset for distances up to 10 metres.

Expand your system in the future with the addition of ICOA SUBs which can be operated in parallel, giving you more and more power. By using two (or more) subs, you can also take advantage of the cardioid-preset. Simply position the additional subwoofers next to your ICOA SUB facing to the rear and enable the cardioid-preset to get a quieter and controlled low-end at the back while still keeping the punch at the front. This is the perfect way to control noise levels for neighbours or to resolve feedback issues when subs are placed in front of the stage.

Whether you’re playing to a dance floor or just want to add some oomph to a multimedia presentation, the ICOA SUB18A can deliver as much bass as you want, to get people rocking or simply boost audience engagement.

The rugged housings made of 18 mm laminated wood can be stacked, while the M20 thread on top lets you mount the main speakers using a distance pole. The ICOA SUB18A is ideal for use with the ICOA 15A.

Rubber covered aluminium grips offer security whilst transporting the SUB and corner protectors guard the edges during setup. Optional rollers can be fitted to the rear to simplify transportation.

Whether you're a DJ, singer-songwriter, rock or party band, the ICOA SUB produces the perfect bass to complement your live music. Lectures and multimedia presentations also benefit from its clarity and powerful presence.
