Powerbass 3XL-1510D 15" Subwoofer

The Powerbass 3XL-1510D is a 15-inch dual 1-ohm subwoofer built for high-power ported bass applications, delivering 1500W RMS and up to 3000W peak with a robust triple-stacked motor and DDC architecture for deep, controlled low-end. It’s aimed at serious car-audio enthusiasts who demand real wattage, durable construction, and precise bass in a portable footprint.

• Dual 1-ohm nominal impedance: Enables flexible wiring options for multi-amp or single-amp setups, helping tailor load for optimal amplifier stability and control.
• Power handling: 1500W RMS / 3000W max: Supports sustained high-power bass in a tuned ported enclosure while preserving excursion and linearity under demanding peaks.
• 15" pressed/paper cone with DDC coating: Combines strength and lightness for wide excursion with reduced cone resonance, improving mid-bass clarity at high output.
• High Roll NBR surround: Maintains cone alignment during long strokes and high excursions, contributing to controlled low-frequency extension.
• 3.5" vented HD BASV voice coil former: Large-diameter coil with venting supports heat dissipation and sustained power handling during bass-heavy sessions.
• Non-resonance DDC coated cast aluminum basket: Rigid, non-resonant frame to minimize coloration and mechanical noise, enhancing overall clarity at high SPL.
• XTRA large triple stacked motor structure (BL 17.86): High magnetic flux for strong control of the cone, enabling tight transients and deeper bass in sealed or ported enclosures.
• Square spring-loaded nickel-plated push terminals: Secure, corrosion-resistant connections with reliable, repeatable wiring harnessing.
• Ventilation and cooling: Aero-Vent voice coil cooling vents: Improves thermal management during extended bass energy, reducing thermal compression.
• Optimally designed for ported enclosures: Specifically tuned to maximize output and efficiency in tuned ported boxes, delivering powerful low-end extension.
• Frequency response: 25 Hz – 450 Hz; Fs 29.4 Hz: Capable of deep bass onset with a strong bottom end, while maintaining usable output into the upper bass range.
• Cutout diameter: 14.06 in (357 mm): Requires a precise mounting hole size, ensuring a secure fit in compatible enclosures.
• Magnet size: 370.23 oz: Substantial magnet mass contributes to high control and dynamic response under demanding low-frequency content.
• Voice coil size: 3.5 in: Large diameter supports extended linear excursion and improved cooling for high-power operation.
• Mounting depth: 11.2 in: Requires sufficient trunk or enclosure space; compatible with deep-install audio builds.
• Sensitivity (1W/1M): 87.27 dB: Indicates how efficiently the driver converts power to measurable SPL; pairs with appropriately matched amplifiers for strong output.
• Overall size: 15 in: Large-diameter woofer designed for substantial bass production without excessive footprint.

In a properly designed ported enclosure, the 3XL-1510D delivers deep, dynamic bass with high power handling and robust cooling, making it well suited for SPL-focused builds and high-output daily driving alike.
