There are only a few different things that make a speaker sound different, and they all show them selves in the frequency response. If running active, there is no reason to "match" speakers. All you need are speakers that can play within the range that you need them to. Even a basic DSP will allow you to set the crossovers to optimize the response, level match individual speakers to each other, and EQ the significant problems.

I seriously doubt that most car audio companies spend a whole lot of time "matching" their speakers. They simply give the designer a mid and tweet and say, "give me a crossover for these." The crossover just sets the filters and level matches the tweeter with a resistor/L pad.
