【UP X4BMW-FRT.1 10cm Coaxial 2-Way Speaker Compatible with BMW 1/3/6/7 Series】

If you’d like a bit more high-frequency clarity and finer sonic detail from your BMW’s factory audio, but you want to avoid any major modifications, UP X4BMW-FRT.1 is an easy option to consider.

This is a 10cm coaxial 2-way type that can be replaced with ease for BMW’s OEM speakers. It’s also a model that’s relatively straightforward for adding/replacing units in models that don’t have a tweeter setup in the front, as well as for trading in the rear speakers. If you want to revisit the sound’s attack and the amount of information in the treble range without significantly changing the OEM feel or usability, it’s well suited to that.

The 13mm silk-dome tweeter produces delicate details while being less likely to feel harsh on the ears, letting vocals and instrument contours sound naturally. The 10cm midrange uses a lightweight yet high-rigidity paper cone and a neodymium magnet. With responsive sound, it’s the kind of speaker that makes it easier to hear clearer vocal placement and subtle expressions—even in music you already listen to all the time.

Compatible vehicles include 1 Series E81/E82/E87/E88, 3 Series E90/E91/E92/E93, 6 Series E63/E64, 7 Series E65/E66, X1 E84, X3 E83, X5 E70, X6 E71, and more. However, even for the same model, there are aspects that need confirmation depending on the model year and the specifications of the factory audio.

Speaker impressions can change not only by swapping the product, but also depending on the installation method, surrounding treatments, and how well it matches the OEM system. If it were me, I’d first check your current audio complaints and the vehicle’s specifications, then decide whether to start with the front or the rear. Let’s sort out together the best approach for how you normally listen—without forcing a complete replacement.
