True Power You Can Feel

The T1D212 Power Series 12" Subwoofer by Rockford Fosgate has a peak power rating of 1600 watts and a RMS rating of 800 watts. This sub will produce some ground shaking bass and is constructed with a kevlar fiber reinforced semi pressed paper cone and a VAST santoprene rubber surround. This woofer is also equipped with Inductive Damping Heat Sink, this helps radiate heat to reduce the voice coil temperature and keeps the sub operating at a safe operating temperature when pumping out high amounts of SPL. Add some bumps in your trunk and enhance your cars stereo system with this Power Series Subwoofer.

 
Rockford Fosgate Swift Terminals

SWIFT: Selectable Woofer Impedance Fused Termination

Making installation faster and easier, Rockford Fosgate developed SWIFT terminals. This system allows the nominal impedance of voice coils to quickly be configured in a Series or Parallel wiring configuration. Removing and inverting the center plug, a Series or Parallel wiring configuration is accomplished. The removable jumper also provides fused protection in severe overload conditions.

 
 IDHS Inductive Damping Heat Sink

IDHS: Inductive Damping Heat Sink

By securing the Inductive Dampening Heat Sink (IDHS) to the top of the magnet structure, Rockford Fosgate is able to improve the efficiency of their drivers. This is accomplished by reducing the amount of distortion and back Electro-Magnetic Force (EMF). The IDHS also radiates heat to reduce the temperature in the voice coil.

 
Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

 
CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

 
Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

 
Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.

This is my first sub ever and I have it in a ported box powered by a Kenwood KAC-9105d amp running at 2 ohms and 900 watts in an extended cab s10. i only have the amp turned up half way and its hard to sit in the truck. For the little extra cash it is totally worth it

I purchased this sub and have it installed into a 1.75" cubic ft. ported box in my Honda Prelude. I am pushing it with a Rockford Fosgate T1000.1 amp @ 1ohm. This sub is as advertised. (very loud!!!!). I replaced 2 Alpine R12's with this one sub and it produces as much bass. I did have my Alpines in a sealed enclosure though. Overall very VERY pleased!! I would recommed Rockford to anyone!!! Also I wasn't unpleased with my Alpines they were GREAT!! I'M just a ROCKFORD guy!!!

I have 2 of these subs in my car now in a sealed box to max recommended specs with an old school power 800a2 to each sub. These hit just as hard as the ported 12" l7s I had in there but sound so much better all the way around! They are tearing my grand am apart! And the new switch for the ohm independence is great and easier to use then wiring both coils. Couldn't be happier with these monsters.

Ordered this RF subwoofer with a RF P700-1BD. Already had made a custom fiberglass vented enclosure. This combo pounds. I have it installed in a Dodge Ram 1500. I am definitely very pleased with the customer service and that my large order was here in 3 days. Awesome!!!!

This is my review of the Rockford Fosgate T2D2 12" subwoofer. This speaker gave me good bass response on all levels. I put it in a 3 cubic foot ported box. It was a pretty loud speaker and hard hitting. I would recommend this sub to anybody looking for a hard hitting sub.
