Powerbass XL-1040T 10" Shallow Mount Subwoofer

The Powerbass XL-1040T is a 10" shallow-mount subwoofer engineered for high-power bass in compact spaces, built for enthusiasts who want strong output from a tight install. It features a proprietary one-piece injection-molded flat cone for accurate, efficient bass and is designed to perform best in a small sealed enclosure.

• Size and impedance: 10" shallow-mount driver with a single 4-ohm nominal impedance.
• Power handling: 350W RMS / 700W max, enabling substantial bass output without overheating in a suitable enclosure.
• Frequency response: 35 Hz – 500 Hz, covering the mid-bass range for impactful in-car music reproduction.
• Sensitivity: 88 dB (1W/1m), indicating efficiency in in-vehicle listening environments.
• Mounting depth: 3.4" mounting depth, facilitating installation in tight spaces.
• Cutout diameter: 9 5/16" cutout, aligning with standard shallow-mount mounting provisions.
• Voice coil: 2" voice coil with a vented KSV former for robust power handling and cooling.
• Cone and surround: Proprietary single-piece injection-molded flat cone with a high-roll Santoprene surround for controlled excursion.
• Basket and cooling: Perimeter aero-vent voice coil cooling vents and a non-resonance polycarbonate/glass fiber basket for rigidity and heat management.
• Magnet and construction: Inverted ferrite magnet with a 116 oz magnet size, paired with chrome push terminals for secure wiring.
• Additional design notes: New PBX logo dust cap and 2.0" vented voice coil former contribute to overall reliability in a compact form factor.

In a real car audio build, the XL-1040T excels in small sealed enclosures where space is at a premium. Its shallow depth, 4-ohm voice coil, and 88 dB sensitivity deliver solid output with efficient amplification, while the flat cone and Santoprene surround maintain linear, low-distortion bass as the enclosure limits would otherwise introduce excess pressure. The vented coil former and aero-vent cooling help manage heat under sustained power, making it a practical choice for tight under-seat or rear deck installs that demand authoritative mid-bass without compromising cabin space.
