So focal utopia 4 way active, no. 7 + 21wx sub off a pioneer p99rs. All set up, been going for a few months, my install has the mid and tweet above dash near A pillars, and mid/bass in bottom of doors with sub in boot. It all sounds great, got it TA'd pretty much right in front of my face, however, when I reverse phase the tweet and mid above dash, everything becomes very, very centred, to the point where i feel like i can reach out and touch the band. Buuut, i feel like it looses all transition between the door speakers, is this purely because it makes the above dash speakers respond first, then the doors are a sort of mild echo a split second later? so in return im kind of cancelling out the natural transition between the speakers? I feel I loose the nice wide stereo image and blend but gain crazy pinpoint accuracy, also mid and tweet sound harsher when reversed, not as warm, much sharper (not really in a good way) Which is best do you think? The pinpoint accuracy is fantastic, there are no floating frequencies, but the field feels very narrow and a bit harsh. And why is this effect happening? FYI everything is crossed with a 36db slope with no gap between crossover points as I want NO overlap in sound between speakers for absolute detail and direction control.
