highs at 6.5khz-
3" at 315hz-6.5hz

it's a '99 expedition
tweeters are in the sails.
3" in the upper mid doors
6.5 low in the doors.
i would like to switch the locations all together to optimize pathlength differences and sound stage. all opinions are valued.
i'm seriously considering replacing the old door panels and building an infinite baffle in the door like glass suggested, maintaining a stock appearence.
also would like to throw the 3" up on the dash along with the highs, but i'm still trying to figure out how to go about this.
i'm in chicago, so i don't think the kicks would be too great an idea.
thanks |

The crossover points are about right, I'd bump the midbass HPF up to around 50 or 60, though. The bigger question is the slope. I'm guessing you're running active x-overs, and I'd try a 12db/oct slope all around for starters, if that doesn't work for imaging, I'd go higher order if you were to keep the drivers spaced out. 12db/oct is a good, natural slope for a car. And of course, you would have to move the x-over points between the drivers closer to each other depending on slope, which will also depend on the type of crossover used.
As far as install, I'd personally do the midbass in door, midrange driver in a kick panel, and tweeter up in the A-pillar or sail panel. |
