[QUOTE="squeak9798, post: 1504237, member: 555320"] It's not always that simple to determine something like that. That theory assumes that all of the drivers are equidistant from your ear (which is hardly ever the case in car audio). Also, phase is not constant. For a first order lowpass crossover (for example), the driver's response is shifted 45 degrees at the xover frequency and only the xover frequency. Plus those slopes don't account for the driver's natural rolloff....you might have a 12db/oct electrical slope, but a 24db/oct acoustical slope because of the driver's natural rolloff. [/QUOTE]
