【BMW Dedicated 2-Way Coaxial Speaker BLAM BM 100 NC | Naturally Upgrades OEM Sound Quality】

BLAM BM 100 NC is a 10cm coaxial 2-way speaker designed exclusively for BMW.
If your factory speakers sound a bit muffled, you want the vocals’ contours to be a little clearer, but you don’t want to change the system drastically—this is the kind of speaker that suits BMW owners.

This model features a coaxial 2-way configuration, combining a high-frequency unit within a 10cm speaker. With a style close to an OEM replacement, it’s easier to bring out information content and separation in the mid to high frequencies.
The magnet uses neodymium, and the design makes it easy to handle even within limited mounting space. In cars like BMW, where mounting-space and OEM-system constraints exist, the advantages of such a dedicated design are especially noticeable.

In terms of sound changes, rather than making everything flashy, the image is that the vocals, guitars, cymbals, and sense of air in the music you normally listen to move slightly forward. It’s a speaker that should be easy to choose if you want to keep the OEM character largely intact while making the sound a bit clearer and more enjoyable.

However, on BMWs, compatibility and installation details may vary depending on model year, trim level, and OEM audio specifications. How you choose also depends not only on the speakers, but on the connections with the OEM amplifier and woofer, the condition of the doors, and whether you plan to further develop the system with DSP and an amplifier in the future.

At LOGON, we don’t decide recommendations by looking at the product alone. While confirming your actual vehicle specifications and your listening preferences, we also propose the necessary installation details.
Even if your direction isn’t fully decided—such as “I want to start with a speaker replacement first,” “I want to improve BMW’s OEM sound quality a bit more,” or “I want to fine-tune the sound while avoiding major modifications”—that’s completely fine. Let’s think together about the best way for your car.
