PowerBass S-1204D 12" dual coil subwoofer

The PowerBass S-1204D is a 12-inch car subwoofer built for enthusiasts who want deep bass from a single driver. It handles 300 watts RMS and 600 watts peak power with a dual 4-ohm voice coil configuration. The wool and paper cone combines with a 142 oz motor structure to deliver output down to 31 Hz. This model suits sealed or ported enclosures in daily-driven vehicles.

Proprietary DDC coated cone and cooling vents

The cone uses a proprietary DDC coating over pressed wool and paper for rigidity and reduced resonance. A pressed 4-layer large roll foam surround supports controlled excursion up to 9.5 mm Xmax. The 2-inch vented BASV voice coil former and perimeter aero-vent cooling vents dissipate heat during extended play. Chrome push terminals and a rubber mounting gasket simplify wiring and sealing against the baffle.

Check enclosure volume and amplifier matching

Verify your enclosure provides the internal volume required for a 12-inch driver with a 5.5 inch mounting depth and 11 11/16 inch cutout diameter. The dual 4-ohm coils allow wiring to 2 ohms or 8 ohms, so confirm your amplifier is stable at the chosen load and can deliver up to 300 watts RMS. The 88 dB sensitivity rating means moderate amplifier power will produce strong output. Ensure adequate electrical system current for the selected impedance.

Questions about this item

How often will the foam surround on the 12" wool woofer need replacing?

The pressed 4-layer large-roll foam surround is built for long-term durability; no scheduled replacement interval applies under normal use.

What thermal limit appears first when the dual 4-ohm coils run at 300 W RMS continuously?

The 2-inch vented BASV voice-coil former and perimeter Aero-Vent cooling vents are designed to dissipate heat so the 142 oz motor structure stays within safe operating temperature.

How much heat and noise does the 142 oz motor produce during all-day playback?

Aero-Vent cooling vents and the vented voice-coil former keep the motor cool, while the non-resonance DDC-coated steel basket minimises mechanical noise at 87.5 dB SPL.
