Match UP C42BMW-FRT.2 – 2-way component upgrade speaker system for BMW
The Match UP C42BMW-FRT.2 belongs to the MATCH UPGRADE speaker line from Audiotec Fischer, a family of vehicle-specific replacements for factory BMW speaker systems, which the manufacturer notes often leave enthusiastic listeners unsatisfied. This set is a two-way component system made exclusively for BMW vehicles, intended to replace the OE front speakers with a direct-fit solution.
Car-specific baskets and connectors allow the drivers to go into the original positions with little effort, while the system tuning targets more precision and dynamics across the whole frequency range. A 25 mm silk dome tweeter is responsible for finely resolved highs, its level can be set in three steps, and the separate crossover includes a bridgeable high-pass filter so the set can be run optimally from a DSP amplifier such as the BMW-specific MATCH UP 7BMW.
Key Features
- BMW-specific design: developed exclusively for BMW vehicles as a replacement for the factory speakers.
- Car-specific baskets and connectors: simplify installation in the original mounting locations.
- 2-way component layout: separate tweeter and woofer with a frequency response tuned for the application.
- 25 mm silk dome tweeter: coated silk dome for detailed, finely resolved treble.
- Coated paper woofer cone: handles the mid and low frequency range of the system.
- 3-step tweeter level: adjust the treble output to personal taste or the vehicle’s acoustics.
- Separate crossover with 12 dB slopes: 12 dB/12 dB filter slopes for tweeter and woofer.
- Bridgeable high-pass filter: lets the crossover be adapted for perfect operation with a DSP amplifier.
- DSP-ready: reaches its full dynamic potential with a DSP amplifier such as the MATCH UP 7BMW.
- System compatibility: can be combined with other MATCH UPGRADE components.
Drivers & Construction
The kit consists of two MATCH UP S1BMW-FRT tweeters with coated silk domes and two MATCH UP S4BMW-FRT.2 mid-woofers with coated paper cones, each mounted in a basket shaped for BMW mounting positions. Two crossovers and tweeter mounting accessories are part of the set.
Acoustic Performance
- Power handling (system): 60 W RMS / 120 W max.
- Impedance: 4 Ω
- Sensitivity: 90 dB (1 W / 1 m)
- Frequency response: 100 Hz – 25,000 Hz
Crossover
The passive crossover is a separate unit with 12 dB slopes for both the tweeter and woofer paths and a 3-stage tweeter level adjustment. Its high-pass filter can be bridged, so when the speakers are fed by a DSP amplifier the filtering can be handled by the processor instead.
Installation Notes
- Tweeter: outer diameter 43.3 mm (1.71″), installation diameter 41 mm (1.61″), installation depth 9.6 mm (0.38″).
- Woofer: outer diameter 119 mm (4.69″), installation diameter 80 mm (3.15″), installation depth 27 mm (1.06″).
- Vehicle fit: the page specifies BMW vehicles only; check the manufacturer’s BMW speaker compatibility chart for the exact model and version (FRT.1, FRT.2 and FRT.3 differ in woofer basket dimensions).
- Recommended amplification: MATCH DSP amplifiers, for example the BMW-specific UP 7BMW.
