i'll be getting an Audio Control Model 11 in the mail shortly....
it's a center channel processor....
i'm sick of trying to get any height out of my center image and well....kinda ghetto'd in a center channel today, and was very pleased with the results....
i have 2 spare channels on one of my amps...so i bridged them to a 2" tangband driver sitting in the middle of the dash...ran it from 175hz up to 20k....tweets on the left and right of the dash doing 5k and up....css wr's in the kicks running ~200-5k....
helped quite a bit....but some things that are supposed to be all the way to the left or right....are creeping towards the middle....me no likey
so....that model 11...separates out all the things that are common to the left and right channels....and outputs them to a center channel....and also sends the left and right signals out.....hopefully next week i'll see how it does....
your HU might take it....what kinda speaker are you using for your center?
