Our take on the Focal IFBMW-S

by Dave Delamere
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.

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.

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

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


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.

Custom-fit speaker upgrades from Focal

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...

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.
Ease of installation, high quality of audio
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!
Free next day in delivery in VA. Plug & play and relatively quick DIY install. Great sound from existing OEM amplifier. Rich tonal quality.
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.
