Add powerful low-frequency sound reproduction to your PA setup with the LD Systems ICOA PRO SUB 21 A, a powered 21" bass-reflex subwoofer with SysCore DSP processing, well suited for live events, club installations, and mobile DJ setups.The subwoofer features a 3000W Class-D amplifier, which drives the 21" woofer and reproduces frequencies as low as 29 Hz with a maximum SPL of 136 dB, plenty of volume to cover midsize applications. SysCore 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 164'. The rugged housings made of rugged birch wood with a polyurea coating can be stacked, while two M20-thread pole cups (top and side) let you mount the main speakers using a speaker pole.
