Product Information

Upgrade the Audio, but Keep the Car Looking Stock

Focal’s IFBMW-C 4” coaxial speakers are sure to please even the most rabid BMW fanatic. Many people realize the pros of upgrading the speakers in their cars, but are afraid of what the end result might look like. Never fear: Focal has not only designed a killer-sounding speaker for your car, they also made it fit behind the factory speaker grilles with little-to-no modification to your car’s speaker wire. The new Focal speakers can even run off of the factory-installed amplifier, but if you’re looking for even better sound, we suggest a small amplifier to get the job done even better.

Please note the “BMW Model Fit Guide” that is a few paragraphs down!

Aluminum/Magnesium Tweeters Get the Details Just Right

High frequency response is handled by a pair of aluminum/magnesium inverted dome tweeters. This metallic blend allows the tweeters to hit ultra-high frequencies without that “sizzly” sound that accompanies inferior metal tweeters. One other feature of note is the inverted dome nature of the tweeter. This helps the tweeter send the high frequencies in a wider pattern in comparison to other tweeter designs (traditional dome tweeters, for example). This will allows a better blend to occur between the woofers and tweeters so you can get some rich, clean sound from your new speaker kit.

Polyglass Woofers

The woofer cones in the IFBMW-C kit are made of a blend of materials to give you an incredible-sounding result: Polyglass. What’s Polyglass? Well, I’m going to tell you about it now. Polyglass is the outcome of molten glass balls being adhered to a pulp woofer cone. This helps not only in the rigidity of the woofer, but also improves the bass response – especially at louder volumes.
