Specific speakers and speaker sets for the BMW 1 (F20, F21), manufactured between 2011 and 2019 (2nd generation). The speakers have the same dimensions, mounting and connectors as the factory speakers, which allows for easy installation and integration into the existing system. We recommend Audison speakers, which are the most advanced in terms of sound and also offer a complete sound solution using a top-of-the-line amplifier with a DSP processor, without any intervention in the original car wiring.
