PW15D4 - 15-inch Dual 4-ohm Subwoofer

The PW15D4 is built for sustained high-output performance, delivering 800 watts RMS through a dual 4-ohm configuration that gives installers flexible wiring options for a wide range of amplifier setups. Its 4-layer high-temperature copper voice coil and active airflow cooling system are engineered to maintain thermal stability under extended, demanding use.

• 4-layer high-temperature copper voice coil for sustained thermal performance during prolonged high-power operation
• High-flux ferrite motor delivers authoritative low-frequency reproduction from 27 Hz to 250 Hz
• Dual 4-ohm voice coil allows series (8Ω) or parallel (2Ω) wiring to match a variety of amplifier configurations
• IMPP cone with polycarbonate spider suspension provides controlled excursion and accurate transient response
• Advanced airflow cooling system reduces heat buildup to protect the voice coil at peak loads
• 168 oz. magnet assembly with a 3-inch voice coil supports the high-flux motor structure for tight, controlled bass output
