ZRX-S18P – 18-Inch Professional Powered Subwoofer


We designed the Gemini ZRX-S18P Extreme Subwoofer for flexibility and performance in a variety of applications. With a powerful 3 digital amplifier and a lightweight durable painted enclosure the ZRX-S18 is at home in a club, at a party or anywhere easily transportable low frequency reinforcement is needed.


An Immense 3,400W Class D digital powered amplifier cuts through crowds while maintaining that polished performance quality the pros crave. The 18” woofer has a 3” high temperature voice coil with a tremendous amount of excursion to deliver extreme heart pounding bass below 38Hz at over 132dB of SPL. The ultra-rigid cabinet includes integrated side handles and a pole mount for adding any type of power top.


The ZRX-S18P meets any performance requirement. It includes a complete set of connections, including full range left and right inputs and pass-throughs, as well as a set of high pass outputs crossed over at 120Hz for flexibility. We didn’t stop there. The ZRX-S18P includes a powerful 24bit/96KHz DSP with presets for live, monitor and DJ plus controls for phase, master volume, and a peak limiting LED. For any venue this subwoofer is the perfect fit.
