[QUOTE="just call me KeV, post: 8805613, member: 656095"] The graphs for a speaker can show it's operating range. This is useful when picking out gear for your vehicle especially if you want to mix and match speakers. You can create overlapping frequency response for tweeters and midranges, midbass and subwoofers. Phase is as simple as positive to positive negative to negative. Sometimes during tuning we reverse the phase as it can add width or depth to the soundstage or raise it above dash level. This is not always necessary. We use pink noise and an real time analyzer to see where the peaks and nulls in frequency response when the speakers are all playing together. This is a tool we can use to see where our system is lacking or where the output is higher than we would like. This is from an rta app used while positioning my phones mic between my Focal headphones. Notice the response. If we had a large dip or peak in a certain freq. we would have a good step in adjusting it. We can do this a variety of ways including crossover points, eq, and even the specific speaker we are using.
