Rockford Fosgate Power T1D412 12" Subwoofer with selectable 2 or 8 ohm impedance


Crowd-drawing bass beats

Rockford Fosgate engineered Power Series subs for ultimate high-power, high-volume bass. The Power Series T1D412 12" subwoofer features a responsive paper cone that's reinforced with the same Kevlar® fibers used in bulletproof vests — a hard anodized aluminum dust cap covers and protects the entire cone, showcasing the glossy Rockford Fosgate logo. The result? You get classic warm bass from a cone that's virtually indestructible.

Serial Numbers Are Recorded and Photographed Per Each Customer Order. Any product returned for any reason Must be returned in its original and serial number matching box / packaging.

More cone area = more bass

Rockford Fosgate uses their patent-pending VAST technique to attach the oversized rubber surround to the cone, increasing available cone area up to 25% so this sub can push more air for even bigger bass.

Extended excursion

A hefty cast aluminum frame provides a stable platform for extreme cone excursion, while an extended pole piece and bumped backplate allow the sub to hit deeper lows without "bottoming out." Special venting in the frame keeps the aluminum voice coils cool through heavy use for consistent bass performance over time.

Fuse-protected impedance selection

Rockford Fosgate outfits Power Series subs with their unique SWIFT™ terminals, which lets you build exactly the system you want — high-power or multi-sub — without complicated wiring. Just rotate the impedance selection jumper to safely choose between 2 or 8 ohms. If you're thinking about adding another sub down the line, this impedance selector simplifies reconfiguring your system.

The jumper is also fused to protect your sub from accidental overload. These subs work equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
