XL-1244D 12-Inch Dual 4-Ohm Subwoofer | Safe and Sound

The XL-1244D is the dual voice coil version of PowerBass’s largest XL subwoofer, combining deep, powerful 12-inch bass with the wiring flexibility that dual coils bring. Rated at 400W RMS with an 800W maximum and reaching down to 26 Hz, its big cone moves a lot of air for serious low end. At Safe and Sound we have spent over 30 years building bass systems, and the XL-1244D is a flexible, great-value way to get genuine 12-inch impact into your vehicle.

Why choose the dual voice coil XL-1244D?

The XL-1244D’s two separate 4-ohm voice coils are its key advantage. You can wire them in parallel for a 2-ohm load or in series for an 8-ohm load, letting you match the subwoofer to your amplifier’s ideal impedance, or combine multiple subs to reach a specific load. If your setup is simpler and a single 4-ohm coil suits you better, its sibling the single-coil XL-1244 covers that, so it is worth matching the version to how you plan to wire your system.

Maximum bass from the XL range

With the biggest cone area in the XL line-up, the XL-1244D is the choice when you want the most output and the deepest extension. PowerBass designed the XL Series for extended low frequency response, and this 12-inch model digs all the way down to 26 Hz. A proprietary non-pressed paper cone with a DDC coating delivers smooth, natural bass with low distortion even at high output, while a large-roll Santoprene surround lets the cone move freely for real impact.

• 12-inch dual 4-ohm subwoofer, 400W RMS / 800W max
• Two 4-ohm voice coils for flexible wiring (2 ohm or 8 ohm)
• Reaches down to 26 Hz for deep bass
• Non-pressed paper DDC-coated cone for smooth, low-distortion bass
• 2-inch vented BASV voice coil former with Aero-Vent cooling

Built to stay cool, and to last

Bass puts heat through a voice coil, so the XL-1244D is built to manage it. A 2-inch vented BASV voice coil former, combined with perimeter and pole Aero-Vent cooling, keeps air circulating to keep temperatures down on long, loud sessions. The non-resonant polycarbonate and glass-fibre turbine-style basket supports dual stack magnets and an extended dome backplate for solid performance, and chrome push terminals ensure strong current transfer from your amplifier. It is happy in both sealed and ported enclosures.
