Add powerful low-frequency sound reproduction to your PA setup with the LD Systems ICOA SUB 18 A, a powered 18" bass-reflex subwoofer with DynX DSP processing, well suited for DJs, singer-songwriters, and rock or party bands, as well as for lectures and multimedia presentations.

The subwoofer features a 2400W Class-D amplifier, which drives the 18" woofer and reproduces frequencies as low as 29 Hz with a maximum SPL of 133 dB, plenty of volume to cover up to 200 patrons. DynX DSP offers three crossover frequencies (80, 100, and 120) and a cardioid mode, which is great for controlling stage volume when using multiple subwoofers. You can fine-tune the subwoofers performance with the polarity-reverse switch and the acoustic delay, which offers a delay line for up to 33.3'. The rugged housings made of 18mm laminated wood can be stacked, while the M20 thread on top lets you mount the main speakers using a speaker pole. A power cord is included.
