Our take on the Rockford Fosgate IBeam IB-200

by Dominic Devito
Rockford Fosgate

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Rockford Fosgate's IBeam tactile transducer gives you the kick of a good subwoofer, without having to crank your system up to a high level. The IBeam attaches to a hard surface in your vehicle, vibrating when it receives a low-frequency signal from your amplifier. You get the feel of powerful bass through your body without high-volume sound output caused by compressed air.

The compact IBeam doesn't need an enclosure, so you can mount it under your car seat or center console — great for small vehicles that just don't have room for a sub. It can handle up to 250 watts RMS, so you can use it in conjunction with a sub or all by itself.

Overview: The Rockford Fosgate IBeam (IB-200) is the next generation of high definition bass solutions. The Rockford Fosgate IBeam tactile transducer offers a new standard in vibro tactile performance. It delivers powerful deep bass and accurate broadband sound output that will improve the sound quality of any music with your home theater system or in your vehicle. It efficiently energizes the listeners auditory cortex without pressurizing surrounding air by transmitting information via bone harmonics and other direct stimulus routes. IBeam localizes bass and reduces "noise pollution" by increasing the portion of tactile sound as "felt" by only the listener. The IBeam provides a frequency Response of 20Hz to 800Hz.

Car Stereo Application: The IBeam's small size (approximately 7" wide x 2" tall x 4-1/4" deep; 3.5 lbs) allows installation in any vehicle and no enclosure is needed.

  • Installation: The IBeam can be powered by any 4-ohm stable amplifier that provides a minimum of 100 Watts RMS into 4-ohms. Amplifiers with 150 to 250 Watts into 4-ohms offer the best results. For best performance set your amplifier's low pass (LP) crossover between 100 Hz and 300 Hz. The IBeam features a pair of compression terminals that will accommodate 16 to 12 gauge speaker wire. The IBeam can be used with or without a traditional subwoofer.
  • Mounting: The IBeam can be mounted in any position and can be completely hidden. For best performance, the IBeam should be mounted to the underside frame of the seat. If your seat does not allow for proper mounting, the IBeam can be mounted under the center console.

Note: Where ever you end up mounting your IBeam, Make sure all surrounding items are mounted firmly and tight. If not, these items will rattle when the IBeam is working.

Home Theater Application: In addition to car stereo applications, the Rockford Fosgate IBeam can also be used in Home Theater applications.

  • Installation: The Rockford Fosgate IBeam can be powered by any 4-ohm stable amplifier that provides a minimum of 100 Watts RMS into 4-ohms. Amplifiers with 150 to 250 Watts into 4-ohms offer the best results. The Rockford Fosgate IBeam has a speaker-level input with a pair of compression terminals that will accommodate 16 to 12 gauge speaker wire. The IBeam has no built-in crossover; a low-pass crossover set between 100 and 300 Hz will offer the best performance. The IBeam can be used with or without a traditional powered subwoofer.
  • Mounting: Contemporary Home Theater Seats will generally accept direct attachment of the IBeam unit. Find a location on the seat bottom that allows solid attachment to wood structural members. The ideal spot is toward the center and rear of the seat bottom. If seat bottom mounting is not used, choose a location on the seat frame near the rear and center. Check for proper clearance from motors and seat adjustment mechanisms. Allow for air space between your IBeam and floor when mounted. In many situations the IBeam tactile transducer can be mounted directly using the 10 built-in mounting holes. The IBeam should be secured using all 10 mounting holes (minimum of 6).

Note: Never use the IBeam to support the seat. Contact your seat manufacturer to obtain their recommendations for vibro-tactile product mounting.

Overload Protection: The Rockford Fosgate IBeam stops operating when its overload protection is activated. Allow the unit's fuse to reset for 3 to 5 minutes and lower your amplifier settings.

A sub augmentation, not a replacement.

Written By mike, indiana on Saturday, August 28, 2010
These are great for augmenting your current subs. If you can hear your subs and want to
feel them more, then this is the better way as apposed to more amp power, more subs and
more others will be annoyed at hearing you thump or your trunk rattle.

Best method is to attach to a small board and anchor it directly underneath to your seat or
take the back seat cover off an anchor it to the springs in the back...you will really feel it hit
hard that no other subs under of 3000+ watts could do or multiples of subs.

Crutchfield Customer Review (What's this?)
I had one Ibeam-200 installed under the drivers seat in my 2008 Dodge Challenger SRT8 along with a Rockford Fosgate P300-1 amp in the trunk and what a difference it made............WOW!!! My vehicle has the standard 13 speaker Kicker audio system which includes a 10" 200 watt powered subwoofer in the trunk which was pretty good but when I added the single IBeam-200 under the drivers seat it was like my vehicle was parked front row , main floor at a rock concert!!! I plan on adding and additional 400 watt amp in the trunk with dual 10" Kicker powered subwoffers to compliment the 2nd Ibeam-200 that will soon be installed under the passenger seat. The only thing that I have to do yet is turn the gain down a bit on my P300-1 amp because even with the remote control adjustment pot set to zero the PTC overload protection feature that is internal to the Ibeam-200 will over heat and shut down for a couple minutes if I listen to music with very heavy base and have the tuner volume turned up a bit too loud. This thing under the seat feels like a disney theme park simulator ride with the remote control pot at max and it may only work at max for a couple minutes with the P-300 amp remote maxed out and the gain pot on the amp set at max.

Rockford Fosgate IBeam IB-200

Written By Keeram, Houston,Texas on Tuesday, September 22, 2009
First of all if you live in Texas and you have one of these. you need to leave. Down here we need real music with real bass. If you cant hear your mid bass then your mid bass sucks. Get some real subwoofers. What the heck is the point of vibrating the car to get the same feel? If this is the direction of car audio subwoofer technology, then I don't want any part of it. I guess I'm going to have to stock up on real woofers so that I don't run out. I returned this the same day I purchased it.

Crutchfield Customer Review (What's this?)
i was skeptical about these, but decided i would try one out. I had one JL 10 in a sealed box in my trunk, and replaced it with a free air 8" in the rear deck beacuse i didnt want boomy bass that drowned out my midbass up front. the 8 gave me the sound of low end, but not much of the feel of low end. I just hooked up one of these Ibeams today and all i can saw is WOW. these things hit! i have one mounted under my driver's seat and now it feels like i have 2 12's in the trunk, except for that its TIGHT. Theres no rattle, they dont drown out your midbass, and it sounds/feels exactly like a really good subwoofer setup. if youre looking to add a lot of clean tight impact to your setup, these will work great.

These perform VERY well if you understand exactly what they are supposed to do. These do not produce sound. They produce the feeling of the bass that would come from a subwoofer. I ran 2 off of a Rockford P300-1 mono amp in a customer's 2007 Dodge Viper that had NO room to effectively do a typical subwoofer that is able to be heard AND felt. We ran some VERY high end speakers in the doors that can produce the sound of bass VERY well without distortion, but just didnt have the feel of the bass. With one of these mounted underneath each seat, directly to the seat frame, it is IMPRESSIVE! My customer is VERY happy. They even "fuzz" the rearview mirror a lot when you listed to the system. Very cool piece. Highly recommend for the person that actually knows what to expect from these and how to set them up correctly. Good job Rockford! We are actually ordering another 2 of these to add to his Viper. 2 will be under each seat to the frame, and another mono amp. Pretty excited to "feel" the difference. By the way, these are VERY compact! You should be able to fit them under pretty much any seat out there. Vipers don't have much under-seat space, and we could actually do 4 to each seat frame if we wanted.
