PW8D4 - Echo Pro 8 Inch Subwoofer - 800 Watts Power Dual 4 OHM Voice Coil, 2" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Impp Cone

The PW8D4 is an 8-inch dual 4-ohm subwoofer built for installations where compact size cannot come at the expense of output. Rated at 400W RMS with an 800W peak, it delivers controlled low-end reproduction down to 32 Hz through a combination of high-flux ferrite motor design and active thermal management. This is a purpose-built driver for builds that demand reliable, sustained performance in a smaller enclosure footprint.

• 4-layer high-temperature copper voice coil sustains peak output over extended listening sessions without thermal rolloff.
• High-flux ferrite motor generates the magnetic force needed for accurate, authoritative bass reproduction across the full 32–600 Hz range.
• Polycarbonate spider suspension provides consistent linear excursion and improved responsiveness at all drive levels.
• Advanced airflow cooling system actively manages heat buildup, protecting the voice coil during high-demand use.
• IMPP cone material balances rigidity and low mass for accurate transient response.
• Dual 4-ohm voice coil allows flexible wiring configurations — 2-ohm parallel or 8-ohm series — to match a range of amplifier outputs.
