ECHO MAX SERIES 10" Dual 4 Ohm Subwoofer - 1,000 Watts RMS Power Handling (SW10D4)

The SW10D4 is a 10-inch dual 4-ohm subwoofer built around a 3-inch black-coated high-temperature voice coil rated at 1000W RMS, making it a strong match for high-output single or multi-sub builds. Its aluminum die-cast basket, vented backplate, and extended pole piece work together to manage heat and maintain clean output under sustained stress. This is a driver engineered for linear performance and thermal endurance, not just peak numbers.

• 1000W RMS / 2000W Peak — handled by a 3.0" (76.5mm) black-coated high-temperature voice coil
• Aluminum die-cast basket eliminates resonance for cleaner low-frequency reproduction
• Extended pole piece with bumped backplate ventilation promotes rapid heat dissipation during high-power operation
• Double-stacked ferrite magnets at 115 oz deliver strong, consistent motor force
• Composite 3K glass fiber cone with massive ridge-strengthened surround for extensive linear displacement
• Custom copper terminals accept up to 4 AWG speaker wire for low-resistance connections
• Dual 4-ohm voice coil wires to 2Ω or 8Ω, offering flexible amplifier matching
