DC Audio PS3 18" Subwoofer

Hand built in the USA, the DC Audio PS3 18" Subwoofer is engineered for extreme bass in sealed or ported boxes—and is capable of open-air installations for aggressive, outdoor-rich car audio setups.

• Power Handling (RMS/Peak): 1250 Watts RMS / 2500 Watts peak — supports high-bass dynamics without clipping when driven by a capable amp in an appropriately sized enclosure.
• Mounting Depth: 9.50" — determines how deeply the driver sits in the enclosure or mounting surface, impacting fitment in tight spaces.
• Outside Driver Diameter: 18.50" — overall diameter that affects enclosure cutouts and fitment in large openings.
• Mounting Hole Diameter: 16.75" — cutout size required for a proper, sealed installation with a gasket.
• VC Diameter: 3.0" — voice-coil diameter influences heat handling and coil winding area under high excursion.
• Displacement:.22 ft — the amount of air moved per stroke, contributing to low-end output for this 18" driver.
• Ohm Options: d1/d2 — dual impedance options to suit different amplifier loads and wiring configurations.
• Sd: 1217 cm — effective radiating area, impacting bass extension and enclosure requirements for predicted response.
• Motor & Frame: FEA-optimized, triple-stacked motor with fully CNC-machined components; cast aluminum black frame with no invert mount, plus a 2.5 mm aluminum shorting ring for precise control at high excursion.
• Ventilation & Build: Rear gap venting and pole vent help manage pressure and heat under heavy bass demands, supporting consistent performance in demanding installs.
• Other construction: Rubber mounting gasket, rubber magnet cover, chrome spring-loaded push terminals, and a 3" hi-temp custom voice coil wound on a black anodized former for durability and reliability.

In real-world builds, the PS3 18" excels in large sealed or ported enclosures and open-air installations, delivering deep, controlled bass with high headroom. Its 1250W RMS rating, substantial displacement, and dual-impedance options simplify amplifier pairing, while the rugged frame and vented motor design stand up to demanding environments like motorcycles, Slingshots, and side-by-sides. Built by hand in the USA, this driver provides the combination of raw bass capability and long-term reliability that serious enthusiasts demand.
