i watchin all the profreesional comments on this here threar
X_Factor, rememeber, fs should not be used to gauge speaker resopnse
I think what went wrong with it was the box design was done on WINISD and d freq response looked good. But when placed in the car, it was a different story.
correct is right, ever speaker,every car every box is different, and thus will sound diferent
in the evo, you will have a peak out to around 50-55hz, but also a natural cabin gain around 42-45hz
so you can afford to tune lower,(if it's ported) to get a maximally flat response
also from what i've seen and used, the prs line from pioneer it a great line, very afforadable as compaired to other brands
a very simple set from pioneer, but it will be pricy-
pionner 880prs/800prs
PRS-D4200F amplifer
TS-C720PRS 2 way component kit
TS-W12PRS sub
now thats a very nice system, that if used correctly can be very competitive in competition
