The Orion HCCA181SPLX stands at the very top of extreme bass performance. Specifically, this 18 inch dual 1 ohm SPLX competition subwoofer is engineered for overwhelming sound pressure levels. As a result, it delivers crushing low-frequency output designed for the most extreme SPL builds. With 7500W RMS and 30000W peak power, it is built for competitors who push systems to the absolute limit.
Additionally, the dual 1-ohm voice coil configuration supports ultra-low impedance wiring. Because of this, the subwoofer pairs perfectly with high-voltage, competition-grade amplifiers. Therefore, the HCCA181SPLX is ideal for record-focused SPL vehicles, extreme demo builds, and full-scale bass walls. Upgrade your system with Orion Hcca Subwoofer and powerful HCCA SPLX WOOFERS
To survive massive power and cone movement, the HCCA181SPLX uses a moisture- and UV-resistant glass fiber paper cone. Moreover, it features a reinforced NBR foam surround designed to handle violent excursion. Together, these components maintain stability and control under extreme conditions.
At its core, the subwoofer uses a huge 4-inch high-temperature voice coil. As a result, it manages intense heat during long competition runs. In addition, a 690 oz triple-stack ceramic magnet motor structure delivers enormous motor force. This design maximizes output efficiency while maintaining control at extreme power levels.
