Match by Audiotec Fischer Stage 4 DSP & Speaker Upgrade Package for BMW E93

You dont even need to program the DSP as there is 1000's of pre-done setting for most cars, simply download the setting for your model and load it via the micro SD car slot and you are ready to go. 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.
