| # Speaker Project # Prototyping the Crossover

> > > We now have a final impedance and frequency response for the potential tweeter and the same for the woofer. We use the measured impedance in the box for both driver and the measured on-axis response for the tweeter (gated appropriately). We use the spliced / merged frequency response of the woofer (merge the nearfield woofer and port then splice the gated response).

> > > At this point we care about the crossover and the sound. Crossover design, more than any other part of speaker design, is an art as much as a science. You will find that literally an infinite number of crossover produce a chart that looks good. They all sound different and you want to pay attention to what makes them sound different / better. Here's the way I do it...
