The ACTION-S18A is a self-powered subwoofer with a direct radiation configuration designed for powerful and extended bass reproduction. Equipped with an 18-inch driver (model 18FW4) featuring a 3-inch dual voice coil and a 20 mm wide sandwich design, the system offers optimized performance and higher output. Additionally, it includes an innovative forced convection circuit that lowers the operating temperature of the voice coil, thereby improving reliability during prolonged use.

The Class-D amplifier with 1500 W peak power delivers exceptional performance, achieving a maximum sound pressure level of 134 dB. The system features DAScontrol™ technology, allowing the variable low-pass filter to be adjusted between 35 Hz and 125 Hz, along with other key parameters via the 24-bit DSP, providing flexibility for various audio applications.

The ACTION-S18A is made from high-quality birch plywood and is finished with a durable ISO-Flex coating, making it resistant to demanding conditions. With M10 mounting points and a robust construction, it is ideal for PA configurations that require solid and reliable bass reinforcement.
