PW8D2 - Echo Pro 8 Inch Subwoofer - 800 Watts Power Dual 2 OHM Voice Coil, 2" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Impp Cone

The PW8D2 is an 8-inch dual 2-ohm subwoofer built for compact installs that demand real output. At 400 watts RMS with an 800-watt peak, it punches well above its size class. A high-flux ferrite motor and 4-layer copper voice coil keep it performing cleanly under sustained load, not just in short bursts.

• 4-layer high-temperature copper voice coil for extended high-output operation without thermal rolloff
• High-flux ferrite motor delivers authoritative low-frequency reproduction down to 32 Hz
• Polycarbonate spider suspension engineered for precise cone control and responsive transient tracking
• Advanced airflow cooling system manages heat during prolonged high-power use
• IMPP cone material balances rigidity and mass for accurate bass at this driver size
• Dual 2-ohm voice coil supports 4-ohm series or 1-ohm parallel wiring configurations
• 50 oz. magnet provides the motor strength needed to hit rated RMS consistently
