DC Audio RS 12" Subwoofer

The DC Audio RS 12" Subwoofer is a purpose-built bass machine in the RSm2 line, engineered for extreme low-end authority with a forced cooling design that uses radial venting around a solid pole to move 100% of the internal motor air across the coil.

• Extremely rigid non-pressed paper cone assembly: Minimizes coning flex under high power for tighter, more controlled bass.
• Multilayered polymer foam surround: Supports linear cone travel and reduces distortion at deep excursions.
• Polypropylene dust cover with DC logo: Protects the motor chamber while adding minimal acoustic damping.
• Triple Stiff 8"OD semi cup progressive roll spiders: Keeps the voice coil centered during heavy bass peaks and high excursion.
• Dual Extra heavy duty interweaved tinsel lead wire: Handles high current with durability for demanding amps.
• Cast aluminum black frame / no invert mount: Rugged, thermally stable chassis with a straightforward mounting orientation.
• FEA analyzed and optimized motor assembly – Fully CNC machined: Precise tolerances and optimized magnetic gap for consistent performance.
• Rubber mounting gasket: Assists with vibration isolation and installation sealing.
• Chrome spring loaded push terminals: Secure, easy-to-use electrical connections for reliable high-power operation.
• Dual 1.0 or 2.0 ohm 3" Hi-temp voice coil: Impedance flexibility with elevated temperature resistance for sustained power handling.
• Dual 220mm Y35 magnets: High-strength magnet structure enabling strong motor force and controlled excursion.
• 12" mounting depth / cutout / outside diameter / voice coil diameter / displacement / power handling / enclosure guidance: Mounting depth 7"; Cutout 11"; Outside diameter 12.5"; VC diameter 3.0"; Displacement 0.17 ft³; Power handling 1800W RMS / 3600W peak; Sealed box 1.0 ft³; Ported box 1.5 ft³.

The RS 12" excels in high-power car audio builds where enclosure size and reliability matter. Its forced-cooling design helps sustain performance, while the large displacement and robust motor/coil assembly deliver authoritative bass in a 12" footprint. The enclosure recommendations provide clear paths for sealed or ported configurations that suit aggressive urban setups or dedicated SPL installations.
