< p> Premium cars deserve premium sound – the basic speaker setup in BMW vehicles does not meet the expectations of ambitious music lovers in many cases. For all those, the tailor-made MATCH UPGRADE speaker systems offer the perfect alternative that opens new horizons of sound. The 2-way coaxial system UP X4BMW-FRT.3 with car-specific baskets provides much better precision and dynamics across the whole frequency combined with a fantastic treble resolution thanks to its 13 mm silk dome tweeter. Especially in combination with one of our DSP amplifiers, e.g. the BMW-specific UP 7BMW, these speakers reveal their full potential in respect of dynamics. See ″manuals″ for compatibility< /p>
