American Bass King Series 12" Subwoofer

The KING 12" Subwoofer from American Bass is built for extreme bass and durable, high-power performance in demanding car-audio builds. It features a regal textured finish die-cast basket, carbon cone foam surround, and a 4.5" high-temperature flat-wire voice coil crowned with a carbon fiber dust cap for rugged, high-output operation.

• RMS Power: 6500 W — continuous power handling for sustained bass without thermal stress.
• Max Power: 15000 W — peak power capability to reproduce dynamic bass transients.
• Impedance: D1 / D2 — dual-impedance configuration for flexible amplifier matching.
• Sensitivity: 82.3 dB — efficiency indicator to gauge output with a given input.
• Voice Coil Size: 4.5" high-temperature flat-wire coil — improved heat dissipation during heavy-duty use.
• Magnet Size: 613 oz, triple-stacked — strong magnetic field for precise control and deep bass.
• Basket Type: Cast — rigid frame to minimize flex and support high excursion.
• Direct Cooling System — active cooling to sustain performance under high power.
• Dust Cap: Carbon fiber dust cap — enhances stiffness and heat resistance at the cone apex.
• Surround: Carbon cone foam surround — controlled cone movement and durability.
• Yoke & Terminals: Black anodized T-yoke, double black spider, 4GA copper push terminals — robust construction and secure wiring for high-power wiring.
• Mounting Depth: 11.02 in — depth required in the installation cavity.
• Cutout Size: 11.34 in — mounting hole diameter needed for installation.
• Ported Box Volume: 3.75 ft³ — enclosure size optimized for vented alignment and output.
• Recommended Amp (Pair): VFL Comp 8K — suggested amplifier pairing for high-demand setups.

In a real car build, this subwoofer excels in a vented enclosure around 3.75 ft³, delivering high-output bass with solid control. The combination of a massive triple-stacked magnet, heat-tolerant voice coil, and direct cooling supports aggressive power delivery, while dual-impedance wiring and rugged terminals simplify integration with powerful amps. The carbon fiber dust cap, carbon cone foam surround, and cast basket contribute to durability and consistent performance in demanding installations when paired with an 8K-class amplifier.
