Action-S218 is a high-power passive subwoofer system that incorporates 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, improving the system’s overall performance as a result. 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. For long-term optimal performance of the Action-500 passive versions, the system can only be a complete sound system when rounded out with our amplifiers and processors with stored presets and limiters. Features:

• Passive two-way system
• Birch plywood enclosure
• Durable ISO-Flex paint to withstand the most demanding environments
• Recommended processor: DSP-226
• Recommended amplifier: PA series
