Match UP X4BMW-FRT.1 – 2-way coaxial upgrade speaker for BMW
The Match UP X4BMW-FRT.1 is part of Audiotec Fischer’s MATCH UPGRADE speaker range, vehicle-specific replacements aimed at BMW owners for whom the basic factory speaker setup is not enough. It is a 2-way coaxial system developed exclusively for BMW vehicles and supplied as a pair for direct replacement of the original speakers.
Car-specific baskets and connectors make installation straightforward, and the system is tuned for more precision and dynamics across the full frequency range. A 13 mm silk dome tweeter supplies high treble resolution. Included inline crossovers allow operation on the OE radio, while the full dynamic potential is reached with a DSP amplifier such as the BMW-specific MATCH UP 7BMW.
