【Subwoofer for BMW FOCAL ISUB BMW 4｜200mm flat subwoofer that fits in the factory space】

With the factory audio in your BMW or MINI, you want a bit more depth in the bass. When you turn the volume up, you can hear it well enough, but at your usual volume the entire music feels a little light.

That’s where the FOCAL ISUB BMW 4 comes in.

Developed specifically with replacement of the factory-installed subwoofer in mind, this 200mm flat subwoofer. Designed to fit within the vehicle’s OEM speaker grille, it strengthens the low frequencies without changing the overall interior look and feel.

Rather than simply making the bass louder, the added thickness in the mid-bass range—the foundation of music—helps vocals and instrument sounds feel less thin. As a result, you can enjoy music more easily across genres such as rock, pop, jazz, and classical.

In particular, it’s a subwoofer that’s easy to consider for those who don’t want to spoil the look of the factory audio, or for those who want to feel changes in sound while avoiding large-scale modifications.

Add musical thickness while keeping the original look

The ISUB BMW 4 is designed to house the unit within the factory speaker grille, without requiring drilling holes in the vehicle or major interior modifications.

Unlike installing a box-type subwoofer in the trunk, it helps you avoid sacrificing the cargo space and aims for a more seamless, less “aftermarket” finish.

However, depending on the vehicle model and grade, wiring methods, interior processing, and whether dedicated parts are available may differ. Even with the same product, the sound cohesion after installation can change depending on the vehicle specifications and the combination with your existing audio system.

At LOGON, we review the vehicle specifications and your current sound conditions, and we’ll help you sort out together whether it’s better to proceed with the ISUB BMW 4 by itself or to consider the front speakers and an amplifier as well.

If it were me, I would confirm the connection with the front speakers and adjust it so that the whole music naturally becomes thicker, rather than just making the bass stand out. If you’re going to add a subwoofer, I’d like to aim for a finish where, when you listen to your usual tracks from the driver’s seat, you don’t just feel “more bass,” but also feel that “the music is coming together.”
