Just wondering how much time you spent listening to the speakers in the location you are making those panels for? When I was trying to determine the optimal setup for my system, I found the best performance occurred with the speakers up off the floor and slightly tucked under the dash. Also, the angle and location of my kicks don't intrude nearly as far into the footwell as yours seem to, although mine are for 5.25" coincident drivers and not a 7" component set...
