ROCKFORD FOSGATE Power 13" T2 Single 1-Ohm Subwoofer

$999.99 USD $1,249.99 USD

The Power T2S1-13 subwoofer features 13-inches of effective radiating cone area and a single 1-ohm voice coil for ease of wiring.

This subwoofer is not just another made with off-the-shelf parts, we wanted something better, and we knew our fanatics demand this as well. Since the original Power T2 subwoofer was designed by one of the leading loudspeaker engineers in the world, there were some lofty goals that had to be reached. Work was done from the ground-up to out-perform it's previous family members, while incorporating valuable feedback from our great network of Rockford Fosgate dealers. They wanted it bigger and badder with dual everything, and we feel that goal was crushed.

Why 13-inches?  Well, this is a combination of the cone and surround assembly described as the "total effective radiating area".  Since this model is so massive, we incorporated dual spiders for exceptional travel of the cone assembly. The motor structure operates very linear for exceptional sonic quality and the IDHS heat-sink gives the subwoofer impressive power handling capacity. Top it off with proprietary input terminals for large gauge cables to efficiently deliver the needed voltage, and this subwoofer is ready to drop the doom!

WARNING: Use caution when installing this subwoofer. It's heavier than Atlas holding a globe on his shoulders.

Secures directly to the top of magnet structure to improve system efficiency by reducing both distortion and back EMF (Electo-Magnetic force). Also radiates heat to reduce voice coil temperature.

The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position. 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.

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%.

Anodized Aluminum Voice Coil Former
Anodized Aluminum Voice Coil Former

Two things generally happen when voice coils heat-up.

  • They can generate heat close to the melt-down temp of their adhesive bonds which leads to eventual failure.
  • Voice coil dc resistance increases and reduces SPL output.

Solution... Rockford Fosgate subwoofers use aluminum formers or voice coils for their excellent heat dissipation and SPL capabilities unlike many other plastic substitutes.">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.

Stitched Tinsel Leads
Stitched Tinsel Leads

Multipoint 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.
