Orion HCCA151SPL – 15 Inch Dual 1 Ohm SPL Subwoofer | 5000W RMS Extreme Bass Power

The Orion HCCA151SPL is a 15-inch dual 1-ohm SPL subwoofer engineered for extreme sound pressure levels, built for competition-style builds and record-breaking bass. It handles 5000W RMS (20000W peak) so you can push serious power with high-output amplifiers.

• 15 inch dual 1 ohm SPL competition subwoofer: dual 1-ohm voice coils enable ultra-low impedance wiring, maximizing power transfer from high-output competition amplifiers.
• 5000W RMS / 20000W peak power handling: withstands sustained and brief high-power bursts essential for extreme SPL runs without clipping or thermal bottlenecks.
• Massive 4" high-temperature voice coil: designed to endure intense power and heat, maintaining performance during prolonged competition sessions.
• Moisture- and UV-resistant paper cone: durable cone material that resists environmental aging while handling aggressive cone movement.
• Reinforced NBR foam surround: supports massive cone excursion and helps keep control during extreme bass demands.
• Polypropylene dustcap for added cone strength
• 690 oz triple-stack ceramic magnet: provides enormous motor force to drive high SPL output at low frequencies.
• Cutout diameter: 383mm / 15.07 inches
• Mounting depth: 306mm / 12.05 inches
• Overall diameter: 422mm / 16.61 inches
• Frequency Response: 21 Hz – 100 Hz
• Sensitivity: 86.02 dB
• Optimized for competition-style enclosures: engineered to maximize SPL output in purpose-built, high-power setups.

In a real car audio build, the HCCA151SPL excels in SPL competition vehicles, extreme bass demo builds, and multi-subwoofer bass walls. Its combination of ultra-low impedance wiring, massive power handling, and a robust motor and cone assembly delivers high output while maintaining cone control, making it well-suited for high-voltage, high-power systems that demand serious bass presence.
