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.

Ridiculous

I have owned these for about four months. Do not buy them if you ever plan on buying something of lesser grade/value in the future. Nothing will ever be good enough again. Wire them @2 ohm in a ported box. I have 2000 watts going to each sub. There's a good chance you may wet yourself with excitement. These subs will flex your roof, windows, doors, etc if wired and installed correctly. I would highly recommend these speakers to anyone even remotely considering. They brought my faith back to the RF product. Back when everything was under rated for competition. You will spend a pretty penny or two on them, but spend it knowing you will never need another sub. Fap fap fap fap.

WOW

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!!!!

Amazing sub

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

Insane!!!

I have two of these in a Birch wood ported box, hooked up to a 1501bd Fosgate power amp, and these slam!!!! The bass is insane! I have the entire trunk covered with Second Skin spray deadener and two layers of Dynamat Extreme, and still the panels vibrate. For the price, you can't go wrong.

Bumpin Hoopty

I love the hell out of this sub. It hits hard!!! High or low bass. My rear view mirror, not very handy they when you got the bass hittin like it does. Sometimes the dude mirrors too. Made my box to specs, wrapped it, & now i can't wait to drive anywhere & everywhere. Friends say its hard to breath. I guess I'm just used to it. Buy this sub!! You won't be disappointed.

Rockford Thunderlude!!

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!!!

Great sub

I've got this sub in a custom center console box for the back of an extended cab f-150. I'ts getting about 2.65 cubes after displacement of the sub and the port. But as far as the sub goes its slams for 1 twelve under 1000 rms. I've got it runnin on a db drive. 1000.1 and it keeps up with all kinds of music. I just wish the sub itself hit the mids a little better. Other than this i think this sub is a pretty good value and I would recomend it.

wow

This sub definatly is worth the cash, even though the T2 looked really nice as well, but a little more costly and id need a upgrade on a amp.
Anyways I built the high output box for this sub and it does really well, of course make it out of 3"4 MDF!

This sub rumbles and shakes my whole truck, i am under watting the sub by a few watts with a kicker sx600 amp and finally after understanding everything it sounded better even though i could have probably gotten a pro to make it sound better, but what the hell id rather know all the things myself for future upgrades.

if you do happen to use the high output box i found it sounding rather better with settings for 63LPF with 24 slope and HPF of 25 with 24 slope and center frequency about 47. i usally listen to rap, produces great lows; i was stunned.
