A Technology-loaded Powered PA Sub
The LD Systems ICOA SUB 18 A is a top-notch powered PA sub with enough juice to tackle a wide range of live sound scenarios. Armed with a 2,400-watt Class D power amp, the ICOA SUB 18 A churns out a 133dB maximum SPL. Its 18-inch woofer, which is bolstered by optimized bass reflex ports, yields earthshaking low end all the way down to 29Hz. The ICOA SUB 18 A's baked-in DynX DSP ensures distortion-free sound, even with the volume cranked, and you get four application presets to ensure perfect balance with the rest of your system. This outstanding subwoofer also supplies you with switchable signal polarity and an adjustable delay line for up to 33 feet. You'll also appreciate the ICOA SUB 18 A's four stacking grooves that facilitate secure installations, as well as its M20 thread and four aluminum handles.
