Overview

The T0D412 12" 4-ohm Dual Voice Coil subwoofer mimics the performance and design from its older Power Series brothers. The T0 subwoofers feature VAST technology that increases surface cone area up to 25% so it performs like a much larger woofer. The FlexFit basket not only looks the part but it provides extreme flexibility for extreme installations. Clean, high tech, and high power handling characteristics let this subwoofer wear the torture-tested "Power Series" badge!

Anodized Aluminum Voice Coil Former
Anodized Aluminum Voice Coil Former

Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.

Damn!

Was running a single 12 p3 on 400 rms, and I found this t0 online. Bought it secondhand, subs still stiff, flipped the fuse to 8 ohms so to only run 400 rms to it. And WOW!!!! Sub is amazing! ATLEAST 3xs more bass than the p3. I love it!!!!
