The AKRO Series ATS218 High-Output Dual 18-inch Active Subwoofer from Avante Audio was designed in the USA, Milan certified, and engineered for medium to large events, to run alongside the Avante Audio AKRO ATL328 line-array series.                                                                                                                                                    
The sub can be set up to form small to large arrays, depending on the venue or application. Composed of dual high-output 18-inch low-frequency woofers with four-inch voice coils and large port tuning, the high-efficiency Class-D switching power amplifier boasts 4800W total peak power, and has a PFC power supply, ensuring great headroom with very minimal distortion. Delivering an exceptional low-frequency response of 32 Hz to 120 Hz at -6 dB, it's equipped with comprehensive German-designed digital signal processing, allowing full system networking, remote monitoring/control including input level, EQ, delay, and low-/high-frequency compensation presets.
