[QUOTE="ninogui, post: 4513076, member: 591208"] Hi there, a quick question regarding time correction, manual settings: I am now running active 3 way mode from the head unit (in a 2 way speaker front stage, the sub has its own amp), in which the rear rca´s are connected to the tweeters, and the front rca´s to the mid bass/mid range drivers (according to the manual). - the manual explains the timmings formulae and calculations, etc, but on the unit itself the variables are cm or in. I yield better sound staging results entering higher cm or in. (at driving position) on the front left tweeter and mid range, then a lower value for the front right ones, the even a lower or 0 value for the sub location. Is this correct, or should it be the other way around.? and if it is correct, which should be for instance the cm value for the front left tweeter and mid drivers; [B]1-[/B] the distance from the front lefts to the subwoofer (the farthest driver in the car) [B]2-[/B] the distance from the front lefts to my ear [B]3-[/B] the distance from the front lefts to the subwoofer minus the distance from the front lefts to my ear strangely enough the best results come from the third option. would someone care to explain.? its a bit confusing what should i be based upon. greets [/QUOTE]
