Focal BMW component speaker system

The Focal component system directly replaces the factory BMW speakers.

A custom sound system upgrade for your BMW

You want to upgrade the factory speakers in your BMW, but you're not interested in making modifications to your vehicle to get better sound. Focal's IFBMW-S system provides you with a huge improvement in sound quality by letting you replace the BMW's front door tweeters and woofers with a set of custom speakers that fit right into the factory locations and plug into the existing wiring. Once these speakers are installed, you'll experience more clarity, punchier midrange, and more detailed bass lines — without having to cut new holes or run new wiring.

Focal BMW component speakers

The woofers and tweeters mount directly to the BMW grilles; you also get mounts in case your BMW didn't have factory tweeters.

Includes most everything you need to complete the install

This package comes with almost everything you need to improve the sound in your car dramatically. You'll find a pair of 4" Polyglass woofers, each in a custom frame that mount to your door perfectly — no adapter needed. You'll clip the two aluminum inverted dome tweeters directly to the factory tweeter grilles. Don't worry if you don't have the factory tweeters — Focal provides you custom tweeter mounts just in case. This system comes with BMW speaker plug connectors, so they plug right into the factory speaker wiring. You'll also find most of the tools needed for the installation in the box.

Sounds great with factory power

Focal designed this set of speakers to deliver superb sound, even when powered by the BMW radio. But this system handles up to 40 watts RMS, so an aftermarket car stereo or an external amplifier will make these speakers sound even better.

Product Highlights:

  • custom speaker system includes two 4" woofers, 2 tweeters, and installation parts
  • fits select 2006-up BMW 1-Series, 3-Series, and X1 models
  • 4" Polyglass woofer with butyl rubber surround
  • aluminum/magnesium inverted dome tweeter
  • in-line crossovers (4,000 Hz @ 18 dB per octave)
  • 4-ohm impedance
  • 5-40 watts RMS power range (80 watts peak)
  • frequency response: 85-22,000 Hz
  • sensitivity: 90.5 dB
  • warranty: 1 year
  • Our 60-day money-back guarantee

Focal IFBMW-S on a 2011 328

Written By Brian, Minnesota on Monday, June 29, 2015

Crutchfield Customer Review (What's this?)

There area a perfect fit for the 06-11 3 series sedan, and seem very well made. Having a set of Focal tower speakers in my home system made me think these would make a significant improvement - probably had lofty expectations. The clarity is improved over stock, however they are noticeably lower efficiency and create an imbalance with the OEM rears. If I shift the fade more to the fronts, the sub-woofers loose some power (they are best when fade is neutral). A local installer said that the MATCH may be a better choice as they are more efficient and all four corners are replaced. Too much work to remove and return.

Pros: clarity direct fit

Cons: require more power than BMW amp provides.

Crutchfield Customer Review (What's this?)

These fit perfectly, they are well made, and sound fantastic. I installed them in my 2008 E90 M3 sedan without any issues. Very, very happy with the results. For the rears, I used Focal Integration ISN 100. The ISN 100s are a poor buy compared to these... the woofer is much lighter weight in the ISN 100 and whimpier. While the tweeters look the same, they have different part numbers. If I were to do it again, I would be tempted to use these IFBMW-S in the front and rear. They aren't designed to fit the rear, but the woofer has the same bolt pattern. If you did try to use IFBMW-S in the rear of a 3-series, you would have to come up with a way to mount the tweeter. That would be the catch, but compared to the price of the ISN-100, it would be worth the effort.

Pros: Fit, quality, sound

Cons: Price

Focal Integration IFBMW-S

Written By Does not fit all 3 Series, California on Thursday, January 22, 2015

Crutchfield Customer Review (What's this?)

Unfortunately does not fit many 3 or 4 series cars - the driver (magnet) is too deep and the window hits the speaker when you lower the window. Be very careful when ordering

Focal IFBMW-S on a BMW 335M

Written By Jerry, Puerto Rico on Tuesday, March 25, 2014

Crutchfield Customer Review (What's this?)

Focal is The Best sound you can buy. super clear tweeters, Excellent Mid make the different in you car. The quality of construction is Superior . Custom fit for the BMW.

Pros: Excellent Sound. pure fidelity.

Cons: Price......

Superb Product

Written By Shawn, Lynchburg, VA on Sunday, March 23, 2014

Crutchfield Customer Review (What's this?)

Superb product. However, I own an X1, and figuring out how to install in the X1 was a little "do it yourself". Given, it is intended mostly for the 3 series, but it fits the X1 perfectly. Releasing the BMW connector was a little difficult as well, and some hints on that would have been helpful. If you've ever had a car door apart though, this won't be much trouble.

Pros: Ease of installation, high quality of audio

Cons: Cost, figuring out the install

Much Better than OEM

Written By TC, VA on Saturday, February 08, 2014

Crutchfield Customer Review (What's this?)

First, Crutchfield is a class act organization from which to purchase and I appreciate their level of customer service.

The IFBMW-S is a great OEM replacement option if you want the installation to remain stealth and keep the existing BMW amplifier. From a look and feel perspective, the size and weight of the IFBMW-S vs. the OEM Harman Kardon speaker conveys it's superior quality and potential. It's truly a plug & play system and once installed, the sound quality is amazing - much more definition and vocal quality. Clean, no distortion listening at the highest volume levels. I just replaced the front door speakers and may do the rear doors and deck at a later date, but no rush as I'm satisfied for now. I am definitely new Focal fan!

Pros: Free next day in delivery in VA. Plug & play and relatively quick DIY install. Great sound from existing OEM amplifier. Rich tonal quality.

Cons: Focal tweeter not a perfect replacement fit in existing tweeter location in F10 M5. Slight modification to tweeter housing made it work. Door panels are not as easy to remove and reinstall, but that's nothing against the product. Make sure to look up YouTube video to assist you with the installation.

Product Research


Polyglass Cone: The woofer cone has a cellulose pulp base and is coated with a uniform deposit of hollow glass microballs. The addition of the Polyglass layer significantly increases the cone's rigidity without adding much weight. This combination takes advantage of the accuracy and neutrality of the hard outer surface, but maintains the superior damping characteristics of the cellulose pulp.

Surround: The woofers' rubber surrounds are resistant to ultraviolet rays, temperature extremes, and humidity, adding to the system's reliability and longevity.

Inverted Dome Tweeter: Each tweeter uses an inverted aluminum dome, producing a broad sound stage. If the BMW factory system has separate tweeters, the Focal tweeters mount behind the factory grille. If the factory system does not have separate tweeters, use the included custom housings to mount the Focal tweeters.

Crossovers: The included speaker wire has in-line crossovers for the woofers and tweeters. The crossover slopes are 18 dB/octave and the crossover point is 4 kHz.

Product reviews from the Crutchfield Labs

Russ, a Crutchfield employee, didn't like the lack of bass and poor high-frequency clarity in the "premium" system of his 2008 BMW 335i. He decided to try the Focal IFBMW-S and IFBMW-C custom-fit...
