Orion HCCA181SPLX – 18 Inch Dual 1 Ohm Extreme SPL Subwoofer | 7500W RMS Bass Power

The Orion HCCA181SPLX delivers 7,500 W RMS and up to 30,000 W peak from an 18-inch dual 1-ohm SPLX sub, built for extreme SPL competition builds and ultra-high-power systems.

• 18 inch dual 1 ohm extreme SPL subwoofer: Large diameter and dual voice coils provide flexible impedance options, enabling ultra-low impedance wiring for demanding, high-current amplifier setups.
• 7500W RMS / 30000W peak power handling: Specifies continuous and peak capabilities, designed to sustain intense dynamic bursts common in SPL competitions.
• Massive 4” high-temperature voice coil: Engineered to manage heat during long competition runs, helping maintain performance and reduce thermal limitations.
• Glass fiber reinforced paper cone for extreme strength: High stiffness and durability to resist deformation under violent excursion, preserving control at high output.
• Reinforced NBR foam surround for violent excursion: Built to withstand large cone travel while maintaining stability and linear motion.
• Polypropylene dustcap for added cone stability: Adds rigidity to the cone center, helping maintain consistent cone shape under extreme SPL.
• Huge 690 oz triple-stack ceramic magnet: Provides substantial motor force for precise control and high output at extreme power levels.
• Designed specifically for SPLX-level output: Tailored engineering to maximize performance in SPLX-style setups and enclosures.
• Optimized for extreme competition-style enclosures: Enclosure compatibility designed to extract maximum SPL in competition builds.
• Dual 1-Ohm DVC configuration: Flexible wiring options and impedance tuning to meet demanding amplifier requirements and power delivery.
• Non-pressed paper cone and NBR rubber surround: Combines traditional cone material and surround for precise sound reproduction while managing extreme power levels.

Benefits: In a high-output, multi-sub, or bass-wall installation, the HCCA181SPLX is built to survive massive power and cone movement while maintaining control and clarity. It suits record-focused SPL vehicles, extreme demo builds, and high-voltage, ultra-high-power systems, where impedance flexibility and robust mechanical design are essential for achieving extreme bass levels without compromising stability.
