ACTION-S218A is a high-power active subwoofer system that incorporates a 3200 Wpeak amplifier and two 18FW4 speakers with a 3” coil and 20 mm winding depth, double layer and sandwich to boost system power, as well as a new forced convection circuit that works to reduce the effects of coil heating. 
 
 
As part of our company culture, all our systems are developed under a single philosophy: to deliver the highest possible quality in terms of both materials and overall system design. In the ACTION-500 series we use the same birch plywood as our touring systems for a tight, natural warm sound found nowhere else on the market.
