Powerbass S-1004 10" Subwoofer

Powerbass S-1004 10" Subwoofer is a 10-inch, single-4-ohm driver designed for small sealed or ported enclosures, delivering 275W RMS (550W peak) with an oversized motor structure for high-power handling and reliable bass during heavy passages.

• Size & Impedance: 10-inch driver with a nominal 4-ohm impedance to match a wide range of amplifiers and enclosure options.
• Power Handling: 275W RMS / 550W max, enabling strong bass output when paired with a suitable amplifier while maintaining headroom for dynamic transients.
• Cone & Coating: Proprietary DDC-coated paper/wool cone for stiff, low-distortion motion and durable operation under demanding bass signals.
• Surround: Large roll foam surround provides linear cone movement and controlled excursion for louder, cleaner bass.
• Voice Coil: 2" BASV voice coil former with vented coil cooling for better heat dissipation during extended bass duties.
• Basket & Cooling: Non-resonant DDC-coated stamped steel basket with perimeter aero-vent cooling to reduce mechanical noise and temperature rise.
• Enclosure Compatibility: Optimally designed for small sealed or ported enclosures, offering flexible integration in compact builds.
• Frequency Response & Sensitivity: 33 Hz – 500 Hz frequency range; 1W/1M sensitivity of 86 dB, indicating practical output potential with a capable amp.
• Physical Specs: Cutout diameter 9 1/8" (230.1 mm); mounting depth 5.25"; Xmax 9 mm; motor structure 116 oz; Sd 330.06 cm²; Vas 43.8 Ltr.

Benefits: In a compact two- or three-seat car audio system, the S-1004 excels in small sealed or ported enclosures where space is at a premium but strong bass output is desired. The 33 Hz lower limit and 9 mm Xmax support solid bass fundamentals and musical sub-bass without excessive enclosure size, while the 4-ohm voice coil and 275W RMS rating pair well with a wide range of amplifiers to deliver controlled, loud low-end performance. The robust cone, vented coil cooling, and non-resonant basket help maintain reliability and reduce distortion under demanding bass passages, making it a practical choice for enthusiasts building a compact, high-value bass subsystem.
