About: Rockford Fosgate T3S1-19 Power 19" T3 Single 1-Ohm Superwoofer

The Power T3S1-19 superwoofer has a whopping 19-inches of effective radiating cone area for deep bass and features a single 1-Ohm voice coil for easy wiring. This is the largest, most powerful loudspeaker Rockford Fosgate has ever built! The Power T3S1-19 can rightfully be classified as a superwoofer due to its whopping 19-inches of effective radiating cone area! That's right... we don't need no stinkin' 18" subs ... this is for genuine Car Audio Fanatics that want to go BIG like Mannie Fresh. We're talkin' Real Big bass and Real Big power handling in a Real Big ride.

The Power T3 19" subwoofer incorporates technologies never before seen in car audio, like the Injection Molded Foam Surround, making the foam strong and durable like a rubberized material. The Edge Wound voice coil allows the windings to be very close with no air gaps so it stays cool for high power handling capacity. We also engineered a very efficient "Push/Pull" voice coil design with a huge Neodymium magnet for a very efficient motor assembly.
