Product Description

ROCKFORD FOSGATE POWER T1D412 - Dual 4-Ohm Voice Coils, 800 Watts RMS

 

The Power Series T1D412 Dual 4-Ohm subwoofer builds on innovative new Rockford Fosgate technologies. These bad boys have patented VAST technology that increases surface cone area up to 25% so the T1D412 performs like a much larger woofer over the previous model. 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 T1D412 is here!

 

Innovative technologies allow the T1D412 subwoofer to perform like a larger woofer over the previous model. The T1 12” features dual 4-Ohm voice coils, 800 Watts RMS power handling, and includes a grille with integral trim ring.

IDHS™ Inductive Damping Heat Sink

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.

 

 

 

 

VAST Surround - Subwoofers

U.S. Patent Patent Pending

The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area without complicated installation issues. The result provides up to 25% more effective radiating cone area for the same model speaker.

 

VAST™ significantly increases a 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.

A hypothetical comparison of a 2004 Power T1 subwoofer vs. a VAST™ example:


The new patent-pending VAST™ technique is a result of combining a unique design concept with precise manufacturing to provide up to 25% more effective radiating cone area.
 

 

 

 

Stitched Tinsel Leads

Improved reliability and performance by reducing fatigue and possible shorting.

 

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.

 

 

 

 

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.

 

Two things generally happen when voice coils heat-up.

  1. They can generate heat close to the melt-down temp of their adhesive bonds which leads to eventual failure.
  2. 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.

 

 

 

SWIFT™ Terminals

Allows nominal impedance of voice coils to quickly be configured in a Series or Parallel wiring configuration. Also provides built-in fusing for protection from voltage transients.

 

Removing and inverting the center plug, a Series or Parallel wiring configuration is accomplished. The removable impedance selection jumper also provides fused protection in severe overload conditions.

 

 

 

 

Flex Fit Basket - Subwoofer

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

The Flex Fit frame utilizes slots (where feasible) instead of single screw sized holes. This allows slight adjustment of the speaker when mounted.

 

 

 

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 damand, not instantaneous power handling, that over time, can damage voice coils.
