Innovative technologies allow the T1D215 subwoofer to perform like a larger woofer over the previous model. The T1 15” features dual 2-Ohm voice coils, 1,000 Watts RMS power handling, and includes a grille with integral trim ring.

The Power Series T1D215 Dual 2-Ohm subwoofer builds on innovative new Rockford Fosgate technologies. These bad boys have patented VAST technology that increases surface cone area up to 25%. The new FlexFit basket not only looks the part but it provides extreme flexibility for extreme installations. Clean, high tech and ready to set off car alarms, the T1D215 is here!

CEA-2031

Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils. Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards.

Stitched Tinsel Leads

Multipoint "periodic" stitched lead wire technique reduces the mass of each tinsel lead and spreads stress and strain over a greater area, significantly improving the reliability and performance of the subwoofer. These stitched tinsel leads withstand extreme duty cycles, fatigue and high current that is critical to robust design. Improved reliability and performance by reducing fatigue and possible shorting.

Klippel Verified

To adorn the ‘Verified with Klippel’ mark, the qualifying company’s loudspeaker engineering personnel must be trained and certified by Klippel prior to using the three separate Klippel systems to design, develop and test:

Klippel DA-2 (Designed)
Klippel PM-8 (Developed)
Klippel QC (Tested)

Rockford Fosgate has made the investment in Klippel to deliver the best possible subwoofers to our customers. Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.

VAST Surround - Subs

Rockford Fosgate's proprietary surround technique, VAST, provides up to a 25% increase in the speakers effective radiating cone area without complicated installation issues. This design alters the typical design and manufacturing technique by eliminating the large flat glue surface area (the landing), which allows the surround to be shifted for increased cone area. In turn, both nominal efficiency and maximum output capabilities are dramatically improved. The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area up to 25%.

FlexFit Basket - Subwoofer

The slot mounted frame pattern of the FlexFit basket utilizes slots (where feasible) instead of single screw sized holes. This allows slight adjustment of the speaker when mounted. The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
