Description
The LD Systems ICOA SUB 18 A is a powered 18-inch PA subwoofer for live sound setups that need solid low end. It suits DJs, bands, venues and fixed installations that need bass support for main speakers. It is built to handle reinforcement work rather than full-range playback, so it fits systems where the sub is doing the low-frequency heavy lifting.
It uses a Class D amplifier rated at 600 W RMS and 2400 W peak, with a maximum SPL of 133 dB. The 18-inch woofer has a 4-inch voice coil and ferrite magnet, and the frequency response reaches down to 29 Hz depending on the preset. It includes Excursion Limiter, peak limiter, thermal overload, over-voltage and over-current protection, plus two balanced XLR and 6.3 mm jack combo line inputs.
In practice, this sub is used alongside active or passive tops in PA systems to add weight and impact to drums, bass and backing tracks. It can be part of a DJ rig, band setup or installed sound system. The box includes one ICOA SUB 18 A subwoofer.
