I've been trying to find this information but I haven't seen anyone doing this or example on anyone doing this.

Traditionally it has always been component speakers, 6.5 inch with tweeter at around 2.5-3khz crossover.


What if we mix and match full range speakers with 6.5inch speakers? the 6.5 inch maybe can crossover at 800hz while the full range will play from 800Hz to 20,000Hz.
With this you bring more of the frequency up to the dashboard and let the 6.5 inch only handle the lower frequency.

Assuming both are using DSP active , has anyone compared the sound quality for both setup ? Component set vs full range speakers + 6.5 inch.

With this the 6.5 inch can focus more on bass performance while the full range on vocals.
